Just had to do a frong and rear bearing on my p38. The noise was bad but no play but once the bearings off the car they were eell notchy. Your really need somebody to drive it while you change position in the car to find the noisy one

Ive had a few people sat in the back and they all say its coming from both sides
Now i cant see both bearings going at the same time
Plus it makes a real racket with the smallest of inputs ie. At 70mph it does it with just the small inputs to just to stay in the lane (ie. no weight shift)
And i had the caravan on the back the other week and it made no differace at all
Im thinking diff and the vibrations are coming up the mounts on both sides? but if anyone wants to meet me and come for a spin to diagnose your more than welcome

Pinion bearings show themselves on the overrun. Like a motor winding down. Weight shift does not change the note. Wheel bearings are a constant noise that changes with weight shift. If you have a mechanics stethoscope and lift the rear end get someone to spin the wheels and put the probe on the hubs in turn, you should be able to hear which side is knackered,

I keep being told wheel bearings so Is there any other bearing hiding in the back end?
Just thinking if its not too much of a big job i might just have both bearings changed to eliminate them
Eather that or theres a guy on ebay selling a whole back axle for £70 would that be a big job? At least i know ive replaced the problem then

diff consistis of 4 bearings 2 for the pinion that normally show noise on overrun first ,and 2 carrier bearings that would show noise under load (and possibly show in the oil ),its is normal for wheel bearings to be worse when cornering as weight goes more to one side ,you can get stiff ujs in props that dont show play but can be felt ,is your v/c seized

A stiff uj and a sezed vc would show all the time wouldnt it? Not just whilst turning
I would be happy to say wheel bearings but the amount of steering input required is so small there is no weight shift like you would expect with a wheel bearing also adding weight to the back (caravan couple of weeks ago and 10bags of plaster last week) makes no differance

most things are worse under load ,and sometimes symptoms arent as youd normally expect but until it goes bang or you rule out stuff your never going to know,you could feel for play in diffs both backlash and diff gears front and back ,same with t/box ,try it with front prop off,drain a little oil out and check it

Was just about to say that James. He has been told what to look for and how to do it. Time to stop arguing the toss and go look.

Short of coming and doing the job for you, there is not a lot else we can do from a sketchy description. We can only suggests what it maybe from what you tell us based on experience. Do you not know a good mechanic who could take a look for you?
