    After doing some research I found that no one has a good write up on the replacement of the torsion bar crossmember bushings. The rubber in the bushing cracks and allows the whole crossmember to sit at an angle and sometimes makes a clunking sound when hitting bumps. I did this on my 2001 Tahoe LS.

    The first step is to remove the torsion keys and push the torsion bars forward out of the way. Then remove the two bolts holding the crossmember. Remove the crossmember.

    You will see three small tabs on one side of each bushing. You need to push those bushings inward using a chisel and hammer. Then, using a punch, begin beating the hell out of the lip on the bushing. It will slowly start pushing out. I destroyed those bushings getting them out.

    Now you're ready to press in the new bushings. For the passenger side I used a piece from my HF ball joint kit to drive the bushing in.

    Now the drivers side was a while different story... The frame does not allow any room to drive in that bushing. Using a threaded rod, some washers, a couple pieces of pipe, and some components from my HF ball joint kit... I was able to press that bushing in.

    I will get the part number for the bushing and post it here. I think they cost me $40 each.

    Let me know if you have any questions and I'll try to help the best I can.

    Nice write-up, thanks. Where did you get the bushings? I bought the entire assembly and had to press the new bushings out of the new assembly to put into the truck.

    Were the symptoms you described the only ones you experienced from the bad bushings?

    Yes, I noticed a clunking sound when hitting bumps. Also, the bad bushings were causing the crossmember to sit at an angle. The tension from the keys is a lot on the rubber bushing.

    Is there no way to change the bushings without having to remove the keys?
