So I replaced my rear shocks beginning of this year, with too much difficulty, and ever since I have had a lot of squeaking when I go over a hump, is this just the springs being seated wrong or is this the bushing in the rear axle brace (think that's what it's called)
Also I was curious as to which lowering springs I should get, I'm not looking for slammed low, but I'm looking for visibly lowered

 

All the answers you could possibly need literally halfway down the page, and a thread dedicated to asking questions...

1. Something isn't installed properly. You should have no noises. (assuming you had no noises prior to the install)
2. My recommendation is H&R. http://www.shiftice.com/spring_strut_decision.html
