I got a set of ST Suspensions XTA coilovers installed on my car yesterday. When I drove it last night and this morning I noticed some squeaking coming from the rear when I first set off but it stopped after just a minute or so of driving. However, on my drive home from work this afternoon the passenger side rear was squeaking constantly when the car was in motion. 40 minutes of that was enough to make me almost lose my sanity. Anyone have ideas of what it could be?
