Thump! Diff Mounts...

[daleynewman]

Hi guys,

i get a good thump from the rear end (you can hear it and feel it) when accelerating after decelerating, or decelerating after accelerating.I've (i hope) narrowed it down to play in the diff mounts. I'm going to replace all the diff mounts, front and rear. But i have a question which i hope you can answer:

I've sourced the following parts which i (think) i need. I only have my doubts about part nr 41653 22010.

part nr 41651 30060 rear lower diff mount (single hole), rubber. CHECK. (1x)

part nr 41651(A) 30070 rear upper diff mount (duo holes) rubber. CHECK (1x)

part nr 41654 22010 front lower diff mount (stopper) rubber. CHECK (2x)

part nr 41653 22010 front upper diff mount (stopper) (2x)........ What's it made of??

I don't know what it's made of... If it's metaal, i won't be needing it. If it's rubber i'll definitely be needing it! Has antbody here had their diff detatched from the subframe and checked/replaced these items?? I'd like to know what it;s made of.

Please, all help is much appreciated. I wil be sooo happy if this problem is solved as it turns a beautiful car into a nightmare to drive car.
