I installed the Aspec suspension kit about a month ago. For the past few weeks, I've been hearing a squeaking from inside the car when I go slow over an uneven surface. Whenever the rear driver's side suspension travels slowly, I can hear it.

Last night, I could recreate the sound by pushing down on the trunk, so I tried spraying lithium grease on some of the bushings that I could reach without taking the wheel off. After spraying them, I couldn't hear the squeaking from just pushing down anymore. But driving it this morning, the squeaking is still there.

Has anyone else had this issue?

 

Exact same thing happened to me after installing some coilovers. I said I would get around to checking it, but never did and it eventually went away.

 

How long would you say it took for it to go away? I've noticed that it only happens when I first start up the car, then goes away after driving for a while. I'll try to spray everything with some white lithium grease when I rotate my tires some time this month.

 

Honestly, I didn't really notice when it stopped, but it might have been right after the break in period.
