For some reason my axle that I swapped in a long time ago (at least a decade ago) came with slotted rear upper control arm brackets. One side is perfectly fine but the other side is wallowed out in the up and down direction so bad that it isn't making a good strong connection on the bushing sleeve when tightened down.
This is the type of old Jeep repairs that I don't enjoy.
Can't get my photo to upload
