Lower Control Arm Rebuilding
Usually if replacing with poly bushings, you don't remove the outer metal sleeve as it has to be reused. Only if replacing with OEM rubber do they come out. This part of a poly suspension rebuild has been a thing of debate, as people have had a hard time getting them to stay in place. I found that I had to hold them in place with a clamp to stay seated, then put torque on the torsion bars while clamped so they wouldn't slide back out. They don't come all the way out, just about 1/4" to keep them from being fully seated. Some people have done modifications to their LCA shaft to help keep the poly bushings in place.
