OT, but a measurement system being soulless & boring? May I enlighten you with the newly-revised SI units, where the Kg (and other units) is no longer a lump of metal but defined by universal constants? Nothing soulless & boring about this, but a profoundly glorious science at work: https://www.bipm.org/en/measurement-units/ the imperial measurement systems is best thrown in the rubbish bin

psi? do you live in the 15th century perhaps? 🤣

Well, those aren't that low-profile: standard size on the RRS is 275/40 IIRC. In the dunes, I dropped to 0.8 bar all around, and the road tyres float very nicely on the sand at that pressure. For the other outings, I stayed on road pressures (2.3F/2.5R), since the terrain was quite hard. So far I've avoided doing very rocky trails due to having road tyres. Once I put on some ATs, that'll change 😁

Thanks @FridgeFreezer, and that was on open ground. You should hear it in town, children and dogs run away scared 🤣 Thanks @deep! Indeed, having done LRE courses almost every year since 2008, it has gradually been 'dumbed' down because it has to start catering for the Evoque, and now the Velar, etc. We go mostly because it's free every time we get a new LR. The last video was a club outing, and I must admit that I did get stuck on one obstacle, no matter what line I took. That same obstacle was also very problematic for a brand new D5, but he managed to clear it due to a few cms more clearance. I may have been able to if I had 275/55R20 tyres, which would have given me 1cm more. but yeah, I bought it to drive fast and to go off-road 😎

Ok, it's been a while, and this is what the new child had been up to since I last posted this clip: Mods: Replaced the rear lights with Glohh ones and replaced the resonator & centre silencer with straight pipes https://www.youtube.com/watch?v=FLAwx9AIVIs https://www.youtube.com/watch?v=C7oh_Kfx4M4 And been on a couple of outings: https://www.youtube.com/watch?v=aAYEInU9BRs https://www.youtube.com/watch?v=P8LTHvQ3LTc

Had a fun time at Land Rover Experience today https://youtu.be/kw2dsVBgmUw

unfortunately sending it back to the UK is not really an option. I will take it to the chap who imports them, he probably has more experience with working with diffs

with the rear prop removed, all noises/vibrations are gone, so it's definitely something on the rear diff/axle

gents, another update on this ongoing saga: after the new crownwheel + pinion were fitted, the droning noise was still there, so the indie took out the ATB and fitted the original diff, and claimed the noise(s) were gone. Picked up the landy just after lunch and noticed that between 0-60kmh, there is a high-pitched whine coming from the rear, similar to the jet whine you can hear when a plan is about to land. Above 60kmh, the whine disappear, and once I get up to 80kmh+, there is still a loud droning noise + vibration coming from the rear. I'm now at a loss regarding this issue (and I'm pretty sure so is my indie), so any recommendations on how to tackle this issue will be much appreciated. thanks!

these might come in handy for some Range Rover/Sport L320/L322/L494 Workshop Manual: http://bit.ly/2iH7jgG

Yeah, it is likely, as this was the first ATB they had ever worked with... if this was their fault, that's the first time in 10 years/4 vehicles that they might have messed up...

Just got an update from the workshop: they fitted a new crownwheel + pinion and the problem is gone, plus one of the bearings was not sitting properly (not too sure about the exact terms). the original diff was replaced by LR after about a year of ownership, so not sure if that was not done properly, and after 9 years it finally went over when the ATB was installed? my indie says now that the droning noise from the diff is gone, there's a 'squeaky' noise that's appeared, and he thinks there's a bearing in the gearbox that needs inspecting

Just spoke to my indie and he says all the adjustments were done during the fitment... so he's going to take it out and inspect it. I kept the original diff, so we have the parts if the diff carrier needs to be replaced.

Thanks Dave, will get him to check that asap! Sorry, my mechanical knowledge is zilch, so I thought the runout & backlash were the same thing.

Thanks, Car was serviced on Monday, diff oil was changed after 1000km on the ATB - no noticeable particles. I removed the rear prop and had it tested, no issues. All tyres were balanced today as well, to rule out tyre wear. Ashcroft say it's probably the backlash on the crownwheel & pinion.
