Title: Prop Shaft Mount
Post by: Ironingboard on 12 May 2008, 19:24:17

Can anyone tell me if the center prop shaft mount is solid metal that the bearing sits in, or is it metal and rubber?

Thanks

right, so the mount housing is metal, then theres a rubber bush which the bearing sits in?  ::)

Yup, a metal frame (pressed steel) with a large rubber donut type insert moulded into it.

The bearing then presses into the rubber donut.

Does the rubber donut come with the metal housing or is it a seperate part?

It comes with the metal housing as its moulded to it.....you got a failed one?

Yeah I think so, I got a garage to take a look and it's looking a bit soft, I had a look while it was up in the ramps and it looks like the prop is sitting on a sponge, mechanic said it was a bit to easy to move.

I get a thump when I boot my car out of reverse. Changed about everything else so this seems to be the problem.

Get a small pry bar on the diff prop flange.....see if there is any lateral movement following a historic bodged pinion seal replacement.

If you look at the rubber mount, it does seem quite saggy......which is normal.

Ok, so I'm looking for movement on the final drive thing that comes out the diff, that connects to a rubber disc and then to the prop. Is that right?

What if there is movement, does that mean someone never tightened the bolt inside the diff correctly. I remember reading that somewhere that this bolt has to be accurately measured before the prop is reconnected.

Hope this makes sense Mark.

Cheers

Correct, if there is play here then the bearing pre-load is not right and hence you either got slop or it buggers the bearing.

Ok, the more I think about it the more I think this might be my problem  :(

Can the bearings be replaced and do you have any idea in how much it might cost?
