This is an unusual situation: tapping out the trailing-arm pivot boltswith a long pin punch and small hammer. In many cases, the pivot boltsare seized to the trailing-arm bushing's inner steel sleeve. Whenthey're seized, rust penetrant doesn't work. A reciprocating saw with aneight-blade placed at the shims is the safest solution for removal. Youcan usually remove shims before using the saw. A torch in this area isdangerous because the fiberglass body is close to the frame and a fuelline above the frame.
