sup ppl, i just have a question, my car when i back up, hit a small hump then my car goes side to side a little and while im driving sometimes , the rear of my car is making this noise, sounds like its hitting something (its a clucking sound) also i just recently installed my eibachs sways bars, it never happen before just after my installation(about 3 weeks ago). i look under it seems like notting is loose. so can any1 help me and tell me or thinks wats goin on, plus i dont think is my shock cuz its only been 2 years since i bought my tein SS . and my car is not slammed thx

 

Are you sure the end links are tight? This is exactly what loose endlinks sound like.
Is the sway hitting the exhaust?

 

i dont think so
