S60 Suspension: - Clunk/ knock from rear

delticol · May 12th, 2014, 19:10

OK, I have a clunk/ knock going on at the rear offside when I go over bumps. It seems worse when cold. I replaced all the drop links a few weeks ago. What do people think? rear shocks???

Any ideas people??

TRear antiroll bar bushes? The ones that mount the bar to the chassis.

Wouldnt the noise be all the time?? this only happens when cold like something is sticking.

A fair point but I'm not sure it would be quite that easy. When I had a noisy top mount at the front it did seem worse when hot. You could well be right about the shocks so certainly worth checking them. At least not to bad to fix, unlike the ARB bushes which I found a real pig - and never really fixed properly with new bushes.

Exhaust, loose battery or spare wheel?

Hello, You're a new member so one thing you'll learn is that "what's this noise?" and "I have a noise" posts have the lowest rate of pinpointing. That goes for all automotive boards.

You can disconnect something like a shock's base and drive it a bit (it will bounce a lot so you won't want to go far) and see if the noise changes.

Had you, for example, disconnected a sway bar link, the sway bar bushings would've been removed from the action as well.

You didn't identify your car. There's no info on your car in your public profile. You gave us nothing to work with. We can't even base guesses on the age of common maintenance items. Kira

Ah sorry, its a 2003 S60D5. Its a strange one, I drove the car today, the weather was warm and guess what, no knocks at all.

Latest update on this. Yesterday I changed the rear shocks as the car had done 120k on the originals (less than £50 from GSF car parts on e-bay) took about 1 hour.... very straight forward job. Took longer jacking it up high enough to get them out. Anyway after taking the car out for a run the knock seems to have been cured but the weather is warm now so we'll see what its like when it gets colder. However I did notice a little knock when I throttle off/on. I cannot determine which end or side of the car this is coming from. The drop links are brand new also and the bushes all appear to be good. I think I will let this one develop.
