CLK 55
Clunk on Shift and On Accelerate
Hi All
I have an 03 CLK 55 w/ 87k on clock. Since buying it I noted that when you shift from PARK to DRIVE you get a noticable CLUNK from the rear. If you shift it back to PARK and BACK to DRIVE again there is no clunk (the same behaviour is exhibited when selecting REVERSE) It's like a noticable clunk from the rear.
When you accelerate or decelerate there is also a knock (not all the time, generally harsh acceleration).
The CLUNK originates from the rear.
I don't think it would be the gearbox as when it drives the gears shift smoothly and the box goes up and down gears with no issues.
IF it is the rear (diff side) - will it likely be diff bushes? if so what do I need to get and are they easy to change? Some people have suggested it could be the main rubber disc between propshaft and diff (Guibo I think) - is it worth me just changing it all?

CLK 55
Can you point me in the direction of a part on ebay? there doesn't seem to be a CLK 55 specific flex plate? I can find a generic CLK flex plate but I'd have thought the 55 would have a more heavy duty plate

Same kit fits a zillion models, both non-AMG and AMG. If one is bad, make sure to replace both.
