    Clunking from the rear question...

    Today I went and replaced my bad rear shock mounts, in hopes that it was the culprit of my clunking from the rear of my car.

    Just to give you a quick synopsis, a couple months ago I had to replace some hard brake lines right above the rear subframe. In order to get to them, I needed to remove my exhaust and drop the rear subframe in order to gain access to it. After reinstalling everything, I was getting a rear clunk, almost as if something in the suspension had play....happens when the car jerks in a forward/backward motion. I took the advice here, and replaced the worn rear top shock mounts which were in fact shot.

    I took it for a test drive today, and the clunk is still there. The shocks are new, which I replaced several months ago along w/ the springs. I guess what I wanted to find out is what other potential areas should i be looking at? Is there any visual way to see if my rear subframe mounts are bad? I had the car up on the lift, and were trying to see if there was any play in them.....but it was tough to diagnose. Visually they look fine. I really want to convince myself that I reinstalled something wrong, but I had a couple friends check it out....and everything seems to be tight.

    Advice needed. Thank you!

    The car is 18 years old, so it is safe to assume that the subframe and trailing arm bushings need replacement as well as the differential mount. In a like manner on a car of that age the transmission and motor mounts are suspect. Any of those could cause a clunk when the drive train loads/unloads.
    The car makes it possible, but the driver makes it happen.

      I agree....the only thing i do find a bit odd is that the clunk happened after I disassembled & reinstalled everything. I'm pretty confident w/ the work I did, I just hate not knowing exactly where the problem is coming from. I even brought it to a shop, and they themselves were baffled. I'm really trying to avoid spending a lot fixing things (that don't necessarily need to be fixed), simply b/c I've misdiagnosed it.
