I seem to have developed a clunk in my car's rear end over the last week. The issue arises when I go over bumps, primarily larger bumps, not so much short/sharp ones. It also happens when I first pull my car out of its parking spot in reverse, but doesn't have anything to do with cornering near as I can tell. I've tried doing a "static compression test" (me trying to compress the suspension manually by leaning on the car) and haven't been able to replicate it. I was guessing maybe an end link or a sway bar bushing, but I haven't had a chance to get the car up in the air yet and so haven't got any exact ideas as to what it could be. Does anyone have any ideas? Thanks!

 

Check the ball joints on the lower trailing arms, toe links and upper arms. one of them has play in it.

I had the same issue and it was my sway bar. I put lateral locks on there (Whiteline SB)

 

Thanks for the feedback. I jacked it up and got a good look; there was a bit of corrosion around a sway bar end link but mainly the screw holding the fuel line that mounts up behind the sway bar was gone. Thus, the line was able to clunk against the chassis when I went over large bumps. I secured the line better and the problem went away altogether. Cheers
