Replaced the all steering rack bushings in situ and the front differential cover bushing (not shown) and one side diff bushing. Also replaced the transmission support bushing, though when I inspected the old support, there was not a noticeable difference in thickness compared to new.
The two round steering rack bushings were shot. The bottom lip was destroyed one one and very thin on the other. I was seeing significant play in the rack and wobble when driving at 25-45 mph.
