When temp is below 30 degrees I get a severe clunking and banging noise over bumps coming from the rear suspension. It feels and sounds like the rear struts are going to come right through the back seat. There is nothing in the trunk and the clunk goes away when temp. Goes above freezing.
Any thoughts/similar issues or resolutions ?
I would suspect that there is a little slop in the shock mounting hardware. When the shocks are cold, the oil inside is thicker and it is absorbing changes slower. If it is bad mounts, that others have reported, it will make noise all the time.
Put it on ramps and have some someone bounce the car while you hold onto the shock. If it's loose, you'll feel it.
