OEM Upper Control Arm Bushing and Positive Caster
After doing some measurements, I believe the UCA ends are off about 0.16", the measurement from the front and rear bushings is short and I did not notice that when I assembled them, because in the process of assembling them on the mounts I had to pull them open a bit in order to make them fit there.
Still, that alone should not cause the bushing to become loose,
The rear bushings on both UCAs have that metal Ring or collar pressed on them and that really locks the bushing in place.
Once the UCAs bores where the bushings are pressed in might have some wearing, I think if I had used the collars in the front bushings that would not have happened.
Again, I believe that setting the UCAs for maximum + Caster squeezes the bushings in a twisted position and that may cause premature failure.
The offset bushings would be a way to go but I heard they are not as durable as the conventional bushings.
