My l322 has knocked out 2 prop centre bearings,it’s just the rubber that fails, infact the actual bearing is fine, just the mounting that collapses. when accelerating hardish it creates a loud banging like the bearing is knocking against the housing, no other noise or vibration, changed gearbox oil, which works fine, changed transfer box oil, which was low and blackish, very grateful for any ideas , thanks

Hi, welcome to the forum.
What year and engine do you have ?
There is an amount of backlash in the transfer box but there is a chain that can wear.
Do you have odd tyres as in wear from front to back / side to side- out of interest, this may not be your problem.

Hi, many thanks for the welcome and reply, much appreciated.
It’s a 2006 BMW ( td6? bit new to all this?) ive owned it for 15 months, it’s on 19” rims however when it arrived 1 of the rears was 18” although fitted with a higher profile tyre, I changed this straight away but maybe this has caused damage/ wear previously?It did knock very slightly shortly I bought it, but it could have been doing it previous as I was still getting used to it as a vehicle. I’ve recently fitted 4 new tyres as the others where shot, these seem to be wearing even and look ok, I’m reasonably competent with mechanics so not a complete beginner but no previous experience with l322.

Depending on the odd tyre profile that was fitted , that could have damaged the transfer box as the L322s permanent 4 wheel drive is sensitive to odd wear on tyres I believe from memory.
I rebuilt my transfer box although there was nothing wrong with it.
Saint or Benble would have more of an idea, I would only be looking it up.
The transfer box does vang under acceleration if the chain is bad, I’ll dig out my photos.

This is the transfer box chain
Hi, thanks for the photos,I’m just trying to narrow it down before getting the spanner’s out, the noise it’s making sounds for all the world like an exhaust knocking very heavily against the body, is the best way I can describe it. And no! the exhaust isn’t knocking against the body!! It bangs hard In quick succession when accelerating from standstill and again if you put your foot down, say to overtake when doing about 50mph. No vibration, gears work smoothly, just this heavy knocking and wrecking the prop centre bearing rubber moulding. Any suggestions anyone? Thanks

Are the UJ's OK? A partially seized UJ will flex the centre bearing.

There was a modification for the front propshaft to diff coupling, that probably wouldn’t knock out the centre mounting but worth checking yours has been done as it does make a noise before seizing up the entire drive train

Get under and have a look, if it's the props it should be pretty obvious, you can speculate for ever. Doubt it's the transfer chain but strange things do happen.

i have only heard of one problem with a transfer box chain slipping, when i replaced the chain and bearings in my transfer box with 110K miles on it the old parts looked as good as the new parts from memory.
