been doing maintenance on the JLU, dw started up again so off came the track bar, replaced worn out bolts as they kept coming lose even with stover nuts, checked toe-in and it was off by 1/2 inch from 1/16, checked caster and it was also off.. hmmm
Put a pry bar on the lower control arms thinking maybe worn bushings when I discovered this through the Gap in the front axle truss:
View attachment 434769
That's the upper control arm front axle bushing squeezed out.
Maneuvered a pry bar in there and sure enough, it moved with ease and may also be the cause of the knock I've been hearing from a stop.
Ordered bushings from the dealership and should be here in the morning, yay upper control arm bushing.
