Well I think thats the end of the P38! I think this all started with a leaking throttle body heater plate gasket. A couple of days ago the temp gauge kept twitching about all over the place. So had a good look under the bonnet and found the heater plate to be leaking. Replaced the heater...

Thank you for your valued and knowledgeable input. I will now just change the MAF on the basis of this and see what improvements are made. I assume that a simple disconnection of the battery for a few hours is not enough to reset the adaptive values? On my E46 M3 the car had to be connected...

Thanks for the advice. I have been experimenting with the MAF sensor being connected and then disconnected. The car seems to be better with it disconnected, however it is only a mild improvement, the revs still seem to be struggling to rise with it disconnected. I will replace the MAF as it...

Been noticing a little hesitation in some rev ranges so decided to put the code reader on the car. Had 3 codes stored. System too Lean Bank 1 System too Lean Bank 2 And there was also a code which I did not read fully which mentioned O2 sensor. However that code has cleared itself. Now I...

Noise from diffs is pretty much gone now. Happens occasionally. I would just like to say thanks to those that have contributed to this thread, you have helped me out a lot. So thanks :)

Just a little update. The wandering has pretty much disappeared from the car now after the wheel and tyre change to 16's. The steering damper has a little play so this will be replaced forthwith. which should improve things even further. The noise from the diffs has improved with different...

I did think this maybe the tyres, but surely they would make noise at all times, not just while de-accelerating? I would have thought that more movement in the tyre wall would amplify any wandering, but then I am certainly no expert in chassis dynamics.

Yes, this forum and other Range Rover forums have been very helpful, as with most automotive forums, they are invaluable when it comes to solving problems etc. I have some mechanical knowledge so not completely in the dark! I have updated one of the other threads with regard to the ride with...

Well what can I say. I have today had 4 brand new 16" alloy wheels with 4 brand new General Grabber UHP 225/65/16 fitted to the P38. The ride of the car has been transformed. There is still a slight wander on certain road surfaces, so I think some bushes still need to be changed. But the ride...

Again, I appreciate all of your valued input. The car is going to Devon 4x4 to be sorted as after pondering for a while I have come to the conclusion that I cannot carry out the work myself due to lack if correct tools. New wheels and tyres going on today so will report back about the...

Thanks all for your responses. Seems there are a few avenues to explore. However, I have since taken the car to Devon 4x4 who will be undertaking the work to put it right as to be honest I simply dont have the correct tools to carry out the job in the proper manner. Probably best to just pay...

Thanks for the info. But can I clarify a few points before I take a spanner to the car! Which nut is this, the one on top of the box with the hex screw in the centre of it? I take it you mean to adjust the hex screw clockwise? Can you expand a little on this please, when you say pre-load...

Thanks for that inforamtion. I will be chaning the radius arm bushes, but not sure if I should go Poly bushes as someone has said its a bad idea. But you seem to be happy with the Poly bushes? Which ones did you fit? Interesting way of doing the ball joints buy putting them in the freezer...

Thanks all for the offers. I have purchased a new set of 4 16" allow wheels off eBay at a low price, never expected to win the auction at that price. I will have to get new tyres put i was going to replace them anway. Thanks again for your help chaps :)

Thanks everyone for your valued input so far. WSLR, I have a few further question for you, if you could expand a little on some of what you have written, that would be great! Regarding the bushes, I have read in a few different places that replacing the bushes for Poly bushes has improved...

It seems not DoZZa, you are the only one who has this problem with the two P38's you have had in the last 12 months!!!! I have a solution.... Sell the bloody thing!!!!

Yes, sorry a P38 I agree, finding the worn part is the best course of action. But I am getting fed up with it. All I have done for the last 2 days is read countless posts on countless forums about this poxy problem which it seems a lot of RR's suffer from. Yet no one seems to have a solution...

Hi all, I my quest to rid my car of its tramlining/wandering I am going to try a set of 16" wheels and tyres to see if this helps the problem, as I have read it may well be as simple as changing to a 16" wheel! I have cash waiting to buy 16's with good tyres if you have any. Or I may swap my...

Does anyones P38 NOT tramline/wander?

Interesting, did not think of the radius arms. Damper seems straight forward to replace, radius arm bushes look like a different animal!
