My SS front end was rebuilt 2 years ago w/ Moog enhanced parts. All new steering components & ball joints, a-arm bushings, end links etc. This year it squeaks over small bumps such as going in a driveway, over speedbumps etc. The left side still pops when turning the wheel sharp while backing out of a parking space or the carport. Yes, the springs are in the right place. It is embarrassing pulling in someplace with all this squeaking & poping going on, plus my ac is dying a loud death. I have sprayed the bushings w/ silicone spray once, but heard no difference. Is there a cure other than taking it apart or del-a-lums? Thanks for the help.
