I rebuilt mine last weekend.. I used MOOG (CK level parts with problem solver components). Replaced: Upper and lower control arms (do yourself a favor, purchase new bolts from GM that mount the arms to the frame. This was a life saver!) Inner and outer tie rods Sway bar links and bar bushings Rear upper control arms Rear lower control arms Rear panhard bar Bought the majority on Amazon, and the control arms at my local Advance auto for ease of warranty if anything should happen.
