My old hub cracked completely so the torsion bar hit the bracket where the hub goes in leaving a sharp edge. This damaged the new urethane bushing, so I ordered a second set. Just peel off all the old rubber and have patience pushing it in.

These are really high quality bushings. However, they are NOT SUITABLE FOR STANDARD MOUNTS. They are too stiff to force them into the mounting rings with pliers as shown in the instructions. I had to improvise a screw press to use them (after much profanity) and they were too distorted to stay in place. I assume they can work with stock mounting brackets, but they will NOT fit stock frame rings.

Perfect fit. I sanded down the factory ribs and worked to replace the old bushings in a vise, not under the truck. It was painful to move with a lever, a hammer, pry and remove the brackets from the torsion bar cross member. That was the hardest part of the job. I didn't put the frame on jacks, that might help.
