Anyone that can help me out, I recently went to a frame shop to figure out the "Popping" underneath my 4Runner when I back up or pull forward with the steering cut to the left hard or right hard. It has an Icon Stage 3 lift on it and it didn't start doing it until recently.

Was told it had something to do with the plastic collar on the steering rod, but that isn't my concern as I've recently took it into a frame shop to see if they could pinpoint the problem.

They said they tightened to LCA on the right side due to it being loose, but now after a week it started making a god awful and very noticable squeak. Could over tightening that LCA be the issue, or could it be old bushings?

Further, I'd like to get all new bushings for my 4Runner and just get them all changed out in one go; Is Rubber the way to go or Poly?
