I installed H&Rs in there rear about a week ago and keep getting rattling noises from both sides. I had Sprints on there and didn't have any noises. I took one side off and redid it but got the same results.

I am sure its not the springs hitting together b/c it makes the noises on small bumps that wouldn't make the spring compress enough to hit each other. Plus, it is a rattle not a clanking.

It sounds like something is loose but I am positive nothing is not tightened down enough. Could the spring not be sitting in there properly? When the spring/strut is assymbled and off the car everything looks and feels solid. What could the probelm be?
