i just had my boxed in subframe installed. after a couple days it started creaking pretty badly. could this be happening if they did not pre load the control arms before they torqued them down? i had it done by a reliable shop but i dont think they have ever worked on a contour before. choices in idaho are pretty limited. any other possible causes? all they did was install the subframe and switch the eibachs for H&R's. It sounds just as bad as it did when the subframe was broken. help.
What brackets are you using to hold the sway bar to the sub frame?
I installed the large diameter Energy Suspension bushings, when I replaced my S/F and they creaked alot after a short period using the grease supplied with the bushings. I have since switched to synthetic brake grease on the bushings and it has stayed quite since.
What exactly is creaking? Is it the sway bar (sounds more like squeaking than creaking)? Under what conditions does it happen?
My experience with "creaking" is that the chassis tends to creak when traversing a driveway diagonally. The rear of these cars is weak until/unless you install a strut tower bar. The trunk pass through is a notoriously "weak link" in the chassis.
Need more info. and observations to correctly diagnose your problem.
