Clunking from the rear over bumps... Anytime it hit any small bumps in the road, I get this clunking / rattling noise from the left rear of the car. At first I thought is was the shock, so I changed them, no change. Then...after reading on ws6.com, I came accross this:
What's the best way to fix this and will it cause the rear of my car to sit higher? Or any other suggestions on what to do about this?
Q: What's that hollow clunking noise from the rear over bumps?
A: A clunk is most likely the rear springs which are "popping" over bumps. If you have squeak, it's probably caused by the metal springs rubbing against their metal perches. In either case, a Technical Service Bulletin (#B005001) calls for the placement of rubber isolators at the bottom of the springs to act as cushion. You can probably do this yourself by wrapping some rubber hose around the bottom coil (down by the axle) of each spring.

If that is the problem then do what it says and use rubber hose. Rubber hose will cause your car to sit higher, but depending on the hose you use, probably not more than 1/8" or so.

Mine does it too. Sounds like something is loose. I haven't had a chance to check anything though. I know with the car sitting on the ground, if I grab a wheel and pull (making the car shake) it will do it also. I'm just hoping it's not a problem with the diff.

It does this no matter what speed I am going. My street is full of potholes and Missouri roads are horrid. So I am constantly hearing it. I'm sure its not the posi. This is a rattling noise, like something is loose. It squeeks rattles and pops depending on how hard the bump is. It almost sounds as if it is inside the vehicle, which is why I thought maybe the shock was loose at the top. Maybe the isolator at the top of the spring is worn out? Like I said it almost sounds like it's inside the car... sounds like something banging against the inside of the wheel well/floor area behind the back seats. I'll get to it this weekend and see if anything needs tightening.

I had the same problem....ended up being a cracked shock mount and broken LCA brackets.
A friend of mine also had the same problem and his ended up being a loose torque arm.
