How thick are the Disco 2 rubberised shock tower retainers compared to the isolators? (Yes I know I could take a wheel off and have a look at mine but I can't be bothered )

Dave you are repeating yourself

With a 2.5P 4th gear might be for use only going downhill with a following wind as well Dave What's the overall diameter of those?

I measured the isolators I had (new and used) with calipers and the new ones were 10mm, the ones that I had been sitting on for a while were down to 9mm so I am working on the basis of 18mm lift for the pair, which is exactly the increase in height at the front bumper from original spec to now, having emptied all the cr&p out of the back of the 90 this evening and measured the unladen height. Having been away for a good run today and bounced it up over a smallish mountain there seem to be no problems at all, though the gear lever resonance is still there at a certain speed the vibration you could "feel" has pretty much disappeared so I think it'll be staying the way it is - its a much better ride than either the original spec (with LR dampers) or the HD springs with gas dampers, I am pleased with the result I think the next thing might be to put them on the bottom of the back springs as well.

Digger90 could put one of them rings on his roof and use it to pull the truck cab back into place I wind my plasma round the spotlights if I need to get it out of the way for a moment - try doing that with wire rope B)

Gary, mine were about £5 each, can't remember exact price. I did immediately notice after swapping back yesterday that the combination of the Monroe gas shocks, the original 175lb springs and the rubber on both ends of them did make the front end ride much better, more like a Discovery in fact a bit more more body roll is noticeable (this is mostly due to the fact that I have a Brownchurch industrial cattle grid on the roof which does nothing for the C of G...) but this is to be expected when swapping from 225lb springs down to 175lb, it is no worse than it used to be with these springs before the isolators were fitted, in fact a little better I think with the increased damping of the Monroes which are a lot stiffer than the std shocks. I think the OME springs most people use are usually about 240lb rating so that is why your ride will be a little choppy, I noticed the difference going from 175lb to 225lb and another increase again would have been too much for me. cheers Stephen

Assuming a 300Tdi with serpentine belt? If you get WD40 on the belts I can tell you it WILL squeal like hell because it was one of the 1,138 things I have tried over the years to stop belts squealing (and 1,137 of them made it worse!) In the long term it might affect the rubber but I doubt whether it would be too serious - you'd chuck them away because of the noise first!

Watching the thing in action it is clear there is a lot of thermal inertia when you nail the throttle to the floor and keep it there (the "peak change rate" is probably about 20 deg per second and I'm sure the EGT goes up quicker than that - when you back off suddenly the displayed EGT keeps rising for a few seconds), but equally once it gets close to the max on sustained full throttle it more or less stops moving, from 600 to 609 probably took 15-20 seconds as did the previous peak I achieved of 603 a few weeks earlier. I see where you're coming from with the argument and I'll pass it on to Ian who makes the kit, I guess the display has to be properly calibrated to the TC so it isn't a case of just finding one and changing it. Any comments/perhaps we should start a separate thread on this subject & it could later be added in to the one that is now in the tech archive?

A series 2 one is older...?

If there was anything like as much rubbish in the boot of your Merc as there was when you dropped my KittyGripper off, I'm not surprised

Might look into that Budgie, but for the time being I'll see if I get a problem with things as they are.

I recently installed the Thermoguard EGT kit and am very pleased with it. The min/max function is good as it means you don't have to watch it all the time to know what peaks it is reaching. My highest so far is 609, that was after about a minute and a half full throttle up a steepish hill in 4th.

One problem I did find - doesn't bother me but would do if I fitted much longer shocks - is that the draglink hits the steering guard when you drop the left side right down: Is this why many of the 3 link folks appear not to use steering guards? I hadn't thought of it before, I just happened to notice while I had it all to bits. The vibration is much less than before - if I hadn't been looking I might not have particularly noticed it - and I ain't taking it all off again to check if removing the isolators gets rid of all vibration besides which it would then be too low again and that would be no good either. I think I'll leave it as it is, though when I crossaxled it this afternoon I found that the tyres (these are only 265/75R16s) are rubbing on the top of the wheelarch boxes at the back so now I need something to lift the back end up. Bah!

Monroe Adventurer gas ones fitted the other week I don't think they dislocate on full droop but I haven't really looked I went away this afternoon for a crash around on some rough ground and got a couple of "twangs" but when I looked there was nothing amiss ... so it might be OK. The spring can't fall off anyway due to the shock going through the middle of it, I am just a bit worried the isolator on the bottom might pop out and end up mashed half way out between the spring & plate. Still got a bit of a vibration from somewhere though even now its lost an inch at the front The one good thing is the ratchet ring spanner I bought - I wish I'd discovered those years ago!!!

Just changed the front springs on the 90 back to the originals to see if that cures the prop vibration, but to raise it a little over what it was I have fitted the ANR2938 rubber isolator rings (usually found on the top of Discovery rear springs) on the top and bottom of each spring - this raises it about 18mm over std. (9mm per isolator) and it now looks about like it should - very slightly lower at the front than the back. But one thing that occurred to me when fitting them is that the "lip" that seats the spring on the isolator is much smaller than the one on the spring plate - so it is possible that on full articulation, the spring may unseat at the bottom more easily. It isn't a problem where the isolators are used in the original place (top of a rear spring) because the spring mounting bracket retains the spring, and the "lip" is just to keep the isolator in place. Is anybody using these things on the bottom at the front, and have you had any problem? I have put them on anyway, and will see what happens, just interested in any feedback.

Another way would be to move them outwards, say about 6 or 8 feet outwards and into a skip I already have my coat thanks, and I left the door open on the way in ready for a quick escape Stephen (leaf spring lover by Royal appointment)

Phew a narrow escape then

Nige I found this and this which would seem to indicate NTC8572 are wot u got...

Nige Just a thought but there can't be many 200 Discoverys that would have any paint at all left on the springs ... the black stuff or the coloured stripes

I think they are Discrubbery rears prob the NTC8572 mentioned which go on the back of a very old Disco, I don't think any of the Discos have dual rate springs on the front and they certainly do on the back cos I had a set on my old old 90, was also what I was looking for to put on the back of the new 90 but none available here ATM

I don't mean to be pedantic but "somebody" calls it LAL. Land Rover - who make it - call it LRC659 - and if I was ordering a Land Rover paint I think I'd call it what Land Rover call it That site has a lot of good info on it but it appears not all of it is right - I noticed something else that was wrong too (only a typo, but...)

I guess it would only increase the ooooomph if you also adjusted the fuelling? Might make the TD last longer than they sometimes do though...

We've had 3 and all the pumps were also mounted in the tank, a combined pump/pickup/gauge thing IIRC I agree - in the battery box prob not a good idea!

Damn, foiled... I thought you were going to come back with "What picture?"

Nige, you stick out like a sore thumb - that photo I have of you, your hat is on the right way round Come on get a grip!
