  1. Hmmmm, I dunno, Rover didn't exactly invest in the brand like Tata have. At least a defender replacement is currently on the cards and whether or not we like the thing from a defender perspective, there's a chance for a few UK or Slovakian jobs. I just don't understand why they don't spend more on quality engineering instead of using quality marketing to replace it.How hard is it to convince the bean counters that building in reliability will ultimately be good for the balance sheet? I saw the attached image on social media, it seemed to fact check ok.
  2. Quite a few did that for the new Mercedes pickup and pulled out when it was actually released. It's a good example of parts bin engineering not working out for a premium brand. I think we're all in agreement that based on current prototype evidence that the defender replacement will just be the illusion of a utility vehicle, but we can live in hope that they make something useful until we're actually proved otherwise.
  3. Revisiting the centre bearing idea, as it's an intrinsic part of the whole thing to minimise as much as possible the propshaft angles. Does anybody know if the UJ in a series front axle is compatible with any of the propshaft UJ's? I'm thinking it wouldn't be too hard to make a bearing housing using the back of a pinion flange to hold one of the bearings as with my original design using transfer box bits. I've chucked all my series stuff out in the dim and distant past as I never saw anything useful in a series axle, kinda regretting it now. Alternatively, using a CV joint in a similar way could work as well, and if I could find matching CV joints that would work even better. There are loads of cars listed in various cv joint catalogues as having 24 spline cv's or shafts, does anybody know if any share the same diameter as the landy ones? I have no idea if it's somehow a standard size?
  4. Doh, I just noticed the title, can an admin change it to wide angle please, there's nothing wise about anything I'm doing. Thanks.
  5. It was the ends that were of particular concern as there's nothing to stop it moving to the side. The sections on the side could also use a brace as they're a long way from the one triangle at the very back. It'll probably end up carrying heavier things than you plan on right now so maybe worth adding the belts and braces now. Good plan though.
  6. Thanks for the suggestions but I need 6 shafts so was just going to knock them up myself. We get conned in the land rover world by having especially short travel joints, I don't think I've come across any UJ in any application with less travel. . The actual UJ is the same in a wide angle joint, it's just the yokes that are different. They won't actually see much load at significant angles as when the axle is hanging, it's light, it's more to avoid any binding. CV joints would be better as I've got some compound angles happening and flanges coming out of parallel. Has anybody successfully used a cv joint from something in a propshaft? I hate to bang on the Toyota drum but they have 35º as standard, It would be cheaper to modify Toyota shafts and make Toyota compatible diff flanges than buy 6 props. I need to conjure up some flanged centre bearings too. I made the thing below from bits of old transfer cases but I couldn't weld the halves together as there's so much oil in the aluminium it's like welding an oily sponge, soaking it in acetone achieved nothing at all. Any suggestions for a really short centre bearing? I'm wondering about using a cv joint and hub from something now, are there any useful bits in a free lander or later independent stuff with handy splines you can put a flange on?
  7. Curiously I've already used them to make a shaft in the past, I wonder why I didn't manage to think of that myself!! I went on to break that shaft about two years later and when I called them for a new bit they were very apologetic that it broke despite me telling them I smashed it on a rock. Thanks.
  8. I need to make a bunch of propshafts for my 6x6 build, where can I get these or equivalent wide angled flange yokes in the UK? These are 1310 but there are 1350 and 1410 yokes with the same bolt pattern that would work as well. Any info much appreciated. I just got my time wasted by some guy on ebay for the last two months so would prefer first hand experience of a decent supplier.
  9. Now you have a mobile inspection pit, awesome!! I'd suggest to add a wee bit of triangulation there just to be safe.
  10. I think we all do and hopefully the engineers at JLR have been busy working on it as the memory of utility land rovers fades across multiple sectors. Modern compact engine mounted hydraulic pumps are easily fitted to any of the common pickups out there now so small hydraulic loads like winches and tippers for the likes of arborists can be easily catered for which used to be the sole domain of the defender. I'd love for the pto to be continued for heavy duty applications needing more than 20kw on the defender replacement but I think that really is wishful thinking as I guess the rear prop will be aligned with the mainshaft as on other JLR products and it would be unlikely they would have a pto equipped gearbox just for the tiny proportion of defender replacements that would order it. V8 land cruisers are awesome, especially the diesel ones. They have a sort of industrial charm about them regardless of how high spec you get and you can still get a brand new V8 common rail diesel without any emissions equipment at all for use in certain markets that still use high sulphur diesel.
  11. The picture with the roof tent is worth a thousand words and I fear anything I might say from here on would just be teaching you to suck eggs. Maybe having a packing checklist to go over might be of interest to some and having a contents list for your vehicle might go some ways towards how you fit it out. For example, do you store the high lift jack on the front, back or the inside? I'm sure we could generate some entertainment from that sort of discussion and maybe something useful could come of it? The only totally random comment I may have purely to further the discussion rather than serious intent might be that given you're going for a fairly radical plan for the roof, would you consider also losing the side panels and basing your build on a pickup instead? The side panels aren't really structural and would probably need modification anyway. You could build a demountable camper body that includes your design thus far but could be extended downwards, rearwards, sideways, etc that it unfolds into something larger than what a 90 is. Your landy is still a 'proper' one in that the windscreen folds down which could make for easier location when hooking the camper body on. Not to mention the opportunities to cruise about in Europe in your sporty convertible. You could keep your current roof and side panels safe in storage should you wish to return the vehicle to standard and possibly the only part you might need for aesthetics might be a tailgate. The picture I enclose is to show some really light jack legs which can also come in handy to level you up or lift you up if you're stuck on the beach. Alternatively some arrangement with a high lift could be employed. My jack legs are made from 50mm box section and were sufficient to lift my demount which weighs about a ton. for a light demount based on a 90, some really light aluminium legs would be sufficient.
  12. Firstly I'd say not to get caught up in building the ultimate overlanding vehicle. My friends spent a few months driving to Ireland from Afghanistan in a 1969 VW beetle and their biggest modification was new strings on the guitar. I'd say get your vehicle mechanically fit, just go and see where you end up. You can book the occasional airbnb or check into a hostel for laundry and a shower. Anything you actually need you can pick up en route and probably cheaper than in the UK. I also think you wouldn't waste any time or money by putting on a roofrack with a floor and go try it out in the uk or somewhere with a tent on top. The few extra minutes every day faffing with a tent as proof of concept will be nothing compared to the time and effort of the project you propose. Lessons learned could be incorporated in the proposed build. The proper roof tents have a very good resale value and might be worth reconsidering? You'd be up und running in days instead of months of preparation. Maybe just focus on what kit you're actually going to take with you and how you're going to live, even temporarily. For example, will you use a petrol stove and cook next to the vehicle? gas? Diesel? Dried food and hot water or fridge and perishables? If you do the fridge thing you might want to sort out a solar panel, they're cheap enough now anyway, you don't even need to fit it, just have a stand and set it up when you need it. You might want an awning on the side and a few somethings to sit on, a table really is handy, do you store it on the drivers side outside or carry it inside? You might want some tools and a few spare filters, maybe a belt at the most in Europe. Add a few clothes, boots, any hobby equipment you might have and you're getting full. Don't try to make your overlanding fit round the vehicle you happen to have right now, if you do get the overlanding bug you'll probably change it to something else.
  13. I had to edit the video really short as the 20mb forum limit was at odds with the original 16mb file size which was too big? This is my friend's disco 5 showing the use of traction control cresting a very gentle off camber climb. Like I said earlier, I'm not too familiar with the modern versions of traction control but I'm also not entirely ignorant of it either and try to keep myself up to date although luckily now I've got Fridge Freezer to keep me right on all aspects of land rover traction control (but obviously not differential locks or anything useful like rope tie downs or any other nasty utility type stuff). Sadly this car was written off a few months after this video when an electrical fault caused a fire and we didn't get the chance to play with it any more although a mornings play was enough to have a pretty good idea of its capabilities. I'd be interested in any observations anybody would like to make. IMG_8072.mov
  14. Exactly!! Common sense at last.... Subaru, audi and mitsubishi do some cool stuff too.
  15. I think you're the one who is a bit out of touch with reality but let's not get personal. I spend my entire working life working with fleets (150 vehicles minimum to secure a visit) of light and heavy off road vehicles, remind me what you do again? Your defence of traction control systems is commendable but either you aren't reading my posts or aren't understanding them. Firstly to save you reading back through my posts you didn't bother to read, I think traction control is good. The problem with traction control systems in remote area fleet management is THEY DO NOT HAVE THE DUTY CYCLE OR RELIABILITY to function for the life time of a vehicle and be cost effective in certain circumstances where it's use is required a lot. You've been told how users in the desert are required to turn it off, I was telling you about coal mines, you've been told about the D2's well known issues with tc and open diffs. Remove yourself from the urban environment for a minute and also from the extreme winch challenge two day or one week event type of activity which is almost more irrelevant than the urban one.Imagine now that you're an untrained driver driving an ambulance on unmade roads or a vehicle on a mine site etc, with no additional user input whatsoever compared to a vehicle without the system, now your brakes only last a month and you don't know why but you do know the parts wont be cheap if you can find them. Compare that scenario to either locking diffs or any version of an improved differential, be it ATB, limited slip, unlocking type, roller cam etc perhaps combined with TC and we can have an informed discussion. I mentioned the brabus unimog as it's an ostentatious obnoxious utility vehicle which will never do a days work and there are relevancies there to the new defender. I shouldn't have to spell that out. I am representative of the market, I've bought over 60 vehicles for various organisations, remind us how many did you buy?
  16. A lot of good points there, the best known and probably the only durable ATB out there is the torsen style, that with TC would be a solid performer but I suppose the cost would be a killer?
  17. There's nobody denying that TC ESP and ABS aren't useful attributes, as already said, it'll have them anyway because it's mandatory. My point is that to a bean counter those systems can be seen to negate the need for locker, and in the urban environment they probably could but I dispute the 99% claim, a typical customer could be the coal mine I was in, those vehicles weren't even road registered, Look to Land Cruiser registrations in Australia if you don't believe this, around 2/3rds of new vehicles are registered to companies, I don't have stats for the 70 series but I bet the global sales would reflect a similar picture. it comes back to the whole premium utility vehicle market argument. At least something like the Brabus unimog had the real deal under the obnoxious exterior. The defender replacement's on the back foot already with independent suspension in this segment, maybe the brakes will be magnetic or something that doesn't wear? We all know the defender couldn't get them because of the feeble half shafts and diffs, the newer ones aren't that much better. An L322 snapped it's front half shaft a couple of weeks ago in Edinburgh and couldn't even drive up the tilt bed. I'm not sure why not? With a decent drivetrain warranty claims wouldn't be an issue as with the hundreds of other vehicles on the road with lockers, They can put a sticker in the cab with the do's and don'ts for the ambulance chasers. The ctis will be a bit of a game changer but it looks like they're making it too complicated in a bid to dumb it down for the lowest common denominator.
  18. They have to due to European legislation. Mr Bosch spoke to his mates in Brussels about this new idea he had sometime before 2008 for electronic stability control which can also combine with antilock braking and traction control. I'm sure it was all to do with safety and nothing to do with anybody making money, a bit like speed cameras in certain places.I firmly believe it's the single and only reason the poor old defender ever got it, without EU legislation it would probably have had drum brakes and no abs!!
  19. I've seen it with my own eyes, two identical vehicles near Dubai in the UAE trying to get up a dune, one with traction control and the other with lockers.. The one using lockers got up, it just doesn't work trying to get up a dune or a hill by putting the brakes on. Defenders fitted with traction control in an opencast coal mine I worked at couldn't go a month before the brake pad back plates were grinding into the discs. There's a time and place for it for sure, maybe disabling it in low range or making it as simple as having it automatically disegage when you engage the diff locks gives the best of both worlds. Haldex is nice for occasional use but none yet made for automotive use has been industrial enough for a defender replacement There's a great video of a white evoque trying to get up a hill and the back wheels just can't turn and the fronts are spinning as the haldex can't transfer the torque. Diff locks by their nature DO apportion torque where they need it!! Differentials do the opposite and apportion it where it isn't needed. Traction control is 100% speed sensitive and not torque sensitive at all. There is no wheatstone bridge strain sensors or other torque measuring apparatus on any on road vehicle in the JLR stable yet that I'm aware of but I stand by to be corrected on this. Sure the traction control is programmed for steering input which may be of benefit sometimes but electronics doesn't win against mechanical in the rough and tumble of the real world. Another issue with traction control systems over diff locks is they force the user to more or less floor the accelerator making wheelspin and losing any chance you ever had of finding grip by backing off as you would with lockers and matching wheel speed with ground speed. You can't use traction control on the idle to creep over rocks in a controlled fashion and you're likely to be traveling much faster with traction control than lockers resulting in more accidents, breakages and injury. I should caveat this by saying I'm familiar with traction control on new Jap vehicles but maybe not JLR ones, the most up to date traction control I'm familiar with is my mates discovery 3. I have another friend with a disco 5 we took off road briefly before it spontaneously combusted due to a heated seat malfunction so I don't feel like I'm up to date to comment on current JLR, just traction control, in general, in my humble experience. One shouldn't be driving a defender in a manner that requires traction control and nanny aids to compensate for a driving style more suited to a sports car. There ought to be an element of driver training as with any machine which serves a purpose.
  20. Weight isn't so much an issue as ground pressure, in fact for most defender duties, heavier is better. Heavier vehicles tow trailers better, have better stability in high winds and crossing rivers, emergency pulling and winching etc. Almost any 4x4 truck over 4 tons say has vastly superior off road performance than a defender in most real world scenarios and requires less maintenance as the parts are sized appropriately. There's a reason that the first thing people do when building an off roader is put larger tyres on with lower pressures and more sidewall flex. Most challenge spec vehicles in the uk would be half a ton heavier than a standard 90. The real problem is when you build a vehicle as heavy as recent discoveries have been and put it on skateboard wheels (as most are), it sinks like a stone in soft ground, other than that, they make a fantastically comfortable tow vehicle and the heavy sprung mass compared to the unsprung mass gives a magic carpet ride on unsurfaced roads. Let's hope the defender replacement can be equipped with 37" tyres from the factory!!
  21. That would be genuinely useful off road and a really positive thing for the defender replacement but the cynic in me is wondering if it's just because the tyre pressures and rolling radii must be kept within stricter parameters for the accuracy of the traction control and abs to be maintained better than previously? I've used CTIS extensively on Russian equipment and it really is very good. All the Russian CTIS equipped vehicles also have diff locks, I hope that concept isn't lost on the defender replacement bean counters and that a fancy traction control system isn't seen as a replacement for diff locks. Taking it too far to measure things like tyre wear might also indicate that tyre choice could be very limited? Another reservation I have is JLR's poor reputation with making durable electronic things, look how complicated that CTIS controller is with ecu's and CAN, the Russians achieved something similar with four taps, a gauge and some driver training. Valves on the wheels could also close off the CTIS system if there was a fault. I hope the defender replacement has a manual backup for when the electronics let all the smoke out. The compressor needs to be another durable item which experience with previous airbag compressors thus far with the brand has not been that impressive. http://www.freepatentsonline.com/20180312017.pdf seems to be a fuller version but good find TSD!!
  22. Ah, that’s it for sure. Bet you don’t do that again! If it makes you feel better you won’t be the last to make that mistake. Now man up and get cracking on the truck so we can read all about it!!
  23. You didn’t even get a tan for all your suffering!! I don’t suppose you have one of those fancy phones that recognises you and does it work if you do?
  24. That's the thread with them in it if you go to page 5. I got some of each recently, both the narrow flanged ones RBK500220 and the wider non flanged ones RHF500130. Both have 16.3mm bolt holes and 54mm diameters and both types I have only have about 14º of angularity. I got them in anticipation of using them for the rear links on the 6x6 Volvo I'm building just now. They're an awkward size as it's not the ID of any handy tube so I'll need to turn some bushings to hold them. I don't see much advantage with the wider ones to be honest as they'll be harder to mount and at least the narrow ones can be spaced to suit a regular rod end mounting if these don't work out. You'll be pleased to know I fully intend to plagiarise your bendy over the axle link idea for my rear bogie links but I'm not near that stage yet, I'm pretty slow and just playing with the front just now.
  25. I wouldn't buy one without trying it on. Some are real b@$t@rds for biting your ears when you flip them up and down. That SIP one has the lighter shades for plasma cutting which is good but it uses batteries which I think is a pain. I'd go down to your local welding supply place or steel stockholder and see what they have in stock. Even that SIP does seem a bit nasty. Parweld, ESAB and Murex all do nice solar helmets at reasonable money. I can totally sympathise with your dose of arc eye, I've had it on more than a few occasions, I've lain there with cold teabags on my eyes pretending they make them feel better, welcome to the club, I bet many here have had it and have nodded sagely at your picture. It's unusual that you got arc eye through your lense, even when not working they're the equivalent in protection of a ye olde shade 15. UVA doesn't go through plastic or glass and the uvb will also be stopped. The protection isn't really the lcd screen. Were you wearing hi viz clothing or around reflective surfaces? Be careful when you get back into it that you don't repeat the same with your new helmet and it's shiny aluminium or a mirror or something doing it. You're also more likely to get a dose of arc eye from the side rather than directly looking at it which makes me also think it might have been a reflection. Really interesting build, keep the updates coming.
