While I was at it I noticed that the body mount I. The extreme rear corners above the rear bumper were doing nothing. There was slop and everything was shaking to its own rhythm.
I decided to pull the bolts. One side came easy, I had to cut the other one out after the impact gun and breaker bar didn’t work.
Once it was out I couldn’t believe how stretched it was!
Look at the neck in the middle. Definitely not from the factory that way.
Replaced the hardware with new grade 8 stuff and adjusted the rubber shim packs (not pictured).
All back together now and nothing shaking around at all!
This is a pretty easy fix if you already have the lower access panel removed.
