Disassembling and rebuilding the steering rack is not hard. There are only a few main parts, the rack itself, the pinion shaft/gear, two bearings, the bushing, two end boots and a shaft seal. The only critical part is to properly lube everything and index the rack to the pinion gear so that the steering wheel sits straight in the center position. IIRC the bushing GM used was bronze (early), steel (mid years) and plastic (on the 88). The rebuilt units that we've seen by Cardone all used the steel bushing.
Rodney Dickman's bronze bushing is high quality and fits perfect. There is no slop in the fit at all. Excellent product.
