"tighten the upper control arm bolts with the suspension loaded".....yes, made sure suspension height was adjusted to where I wanted it BEFORE I tightened them.

"cam bolts are good and tight".....yes, did this when I performed the alignment.

"spray them with Zep45".....didn't use Zep45, but I did try two or three silicone based lubricants on the pass side, nothing helped except replacing them.

"Something is off with the original bushings. Agree good idea to replace the other"......I'm in agreement with this, "the material they used in that run of bushings" probably...though I haven't tried spraying the driver side. Most likely I will have to replace them.

Thanks for the replies,
Jess
