RAD, I might be having the same issue, but I'm 85% sure that mine is actually just a loose shock. It only happens on the driver's side, hard break, turn, or accelerate. Been this way for as long as I have had it.

Initially I also suspected my upper shock mounting.

I found signs of shock mounting rod not centered with previous shocks.



So (before I found the issue with the control arm), I inspected my couple of year-old shocks for above problem, but found none. Then, I removed both shocks and drove slowly around the neighborhood, including speed bumps. Creak remained

Thanks, Slacker. Creak went away after this last alignment, but, yes, bushings would be my next suspension project.
