l’m replacing my silencers and l noticed that after putting the car on axle stands and then removing the rear wheel nuts (with the gear selector in park and rear wheels off the ground) that the passenger side was solid when undoing the nuts but the driver side had movement as l undid the nuts.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi all. I’ve had a ”clunk” noise from the rear when taking up drive from a standstill. Only seems to happen when a bit more spirited pull-off. l’m replacing my silencers and l noticed that after putting the car on axle stands and then removing the rear wheel nuts (with the gear selector in park and rear wheels off the ground) that the passenger side was solid when undoing the nuts but the driver side had movement as l undid the nuts. l could "rock” the wheel as if there was slack in the driveshaft. Could this be the "clunk”? Should there be no slack on the driveshaft? Any comments welcome. l plan to check all around when l’ve completed removing the silencers tomorrow. Thanks 2002 Tip.

POST 2Original post

I'd be tempted to check the engine and transmission mounts first. I can't remember for sure, but I recall a bit of backlash in the drive shafts. (Or maybe its my imagination).

POST 3Original post

Pretty certain there is an allowable amount of play in the driveshafts. The best way is to get the car on a lift to check as Richard mentioned, drive train components and rear suspension links.

POST 4 / ORIGINAL POSTEROriginal post

Thanks for replies. I’ve removed engine mounts and they’re shot. Squelchy and leaking. Manufacturing stamp is wk51 01 so are original. New ones coming tomorrow.

This is a source reference. Confirm exact model applicability in the original material.
