Hello,
My local indie has just replaced the front disks on my 2.5 at 72K.
They were pretty well rusted on, and quite a lot of force and application of
FBH (hammer) was apparently used.
I have now noticed a slight whine from the final drive area at around 2800
rpm in fifth (approx 80mph). Any idea if/what may have been damaged? I
would have thought that the final drive area was pretty robust. Or maybe
the whine is from the new balancer/alternator belts. But I doubt it. Or
wheel bearing?
Any suggestions? How is the "end float" on the drive shafts controlled on
these machines?
This is difficult to handle, as it is probably around twenty hours work to
strip down and check. And is it worth it? However, a similar whine (from
100k) on the final drive of my Peugeot 405 developed into the demise of the
differential bearing at around 225K...
P.S.

Have to agree with the general points in answers on that other forum.
Been there & tried hours of bashing to remove a dodgy stuck brakedisc (rear) - result was a rumbling wheel bearing - when brakes finally sorted and car tooked out for test drive.
I believe the driveaxles on the XM is much like the BX design - a spring is fitted as endfloat control inside inner CV joint - constantly forcing the axle outwards.
On RHS long axle a support bearing is fitted in engine mounted housing.
I don't think diff or support bearing would be impacted by the bashing on the disc - the energy have to be taken up by the wheel bearing & hub mounts.
I would not take this as bad workmanship - but lack of experience at the garage. They should have informed you that the wheelbearing would most likely have to be replaced - due to the stuck disc problem.
Now you have to pay extra time again to get at the wheelbearing - removing the new disc - could have been sorted out in 1 go at first.

My disks fell off when I removed the screws ???

When I replaced my Xantia's discs, the o/s fell off, the n/s was well rusted on. Lump hammer wouldn't move it. Had to resort to turning the blow-lamp on it.
