When I was reassembling the torsion bars, I found the same crossmember bushing problem on driver's side. You will probably have to unload torsion bars to repair. Once bars are out, remove cross member and drill out the rivets to remove the mounts, the new mounts come with bolts to replace the rivets.urns out that the bushing at the end of the cross-member where the rear of the torsion bar mounts is loose (see photos). The torsion bar is firm in the cross-member, but there is alot of movement and knocking in the connection where the cross-member attaches to the frame.
