Morning! I'm not doubting what you say about weight transfer but the range of movement is huge. With it in access mode, that corner is just off the bump stop. In 'normal' mode, it's actually higher than the other three corners. Pretty curious... and I'm not sure it can wholly be explained by...

Hi The rear right air spring is consistently at the wrong height being either too low or too high. When the whole vehicle raises up or down, that corner moves along in sync with the rear left. When using the diagnostic tool to raise or lower just that corner though, you can hear a solenoid...

Mission successful! That was fun :) To re-assemble, I put a piece of wood under the vehicle to provide a smooth flat surface. We then simply heaved the axle back into place whilst sat on two trolley jacks. It was then possible to tinker around with the height / angles to get the radius arms...

I am now properly equipped... You live and learn. My colleague who was giving me a hand to whom I boldly stated "everything is definitely metric" will not let me live this down I'm sure...

Yes, I just discovered that whilst putting the nuts and bolts in my shopping basket. What a muppet I am! Thanks!

The process I used in case anyone is interested was as follows:- Raised the vehicles up and propped under the side members. Axle stands under the axle Disconnected everything that needed disconnecting except the propshaft Used two trolley jacks under the axle, then removed the axle stands...

Finally got round to doing this. Got both axles off today. That was fun! There's a lot more gear lash on the old diff than the new one so I think I'll swap them before refitting. On the 'bad' one, you can turn the flange about 6mm either way before either wheel hub moves. On the 'good' one...

Hi I'll need harder stuff than brews to do this I think. I'm not particularly mechanically inclined as may be obvious from my dumb questions! I'd reached the grand old age of 42 before I took a spanner to a vehicle. I do like working on the RR because everything is massive - there aren't that...

Yep - obvious when someone says it to you!

I don’t think I have the ability to lift it high enough to clear the chassis if I leave the wheels on. Was thinking of making a couple of dollies.

Just thought of a negative... The donor vehicle has 258000 miles on it and the target vehicle only 88000. So I’d be transferring over a potentially knackered diff / driveshafts...

I shall photograph the proceedings! I hope I’ve not missed anything but it really does look massively more straightforward - an order of magnitude perhaps - than doing the individual repairs. Anyone know roughly what a complete front axle weighs?

Hi I need to change all the swivel hub bearings which is a beast of a job and I really didn't enjoy it last time. It was a real struggle and that was with expert help as well. The dilemma is that I have a donor vehicle which has brand new discs/pads/calipers/swivel hub bearings/CV...

Will do - thanks. I have a feeling the issue may be something to do with the pressure sensor. The system is holding air just fine - I can leave it weeks and it doesn't drop at all. Despite this, the compressor seems to be running a lot more than it should be. I've got a donor vehicle which is...

Cheers - I accept all the points you make. The bigger problem I've got is the swivel hub bearings which is a rotten job :(
