E46 diff mountings

[Adam CD P1]

Does sound a bit like diff bushes. Best bet is just to have a look, you can see them just by glancing under the car with a torch. I'd like to bet it's more than likely the rear bush (there's 3 total).

Mine need doing to but nowhere near as bad as you've describe yet, got some powerflex ready to fit.

Cheers dude I'll have a look later on and see what condition there in. Are they easy to replace ? Car's mechanically pretty perfect aside from that
