GMC 7817526 Rack, Piston Nut Kit, Hydraulic Steering Gear

To remove the rack and pinion, start by raising the front of the vehicle and supporting it securely on jackstands. Disconnect the power steering hose fittings and cap the ends to prevent fluid loss and contamination. Pry apart the U-joint plastic shield and remove it, marking the relationship of the intermediate shaft lower universal joint to the rack and pinion input shaft. Remove the intermediate shaft lower pinch bolt and disconnect the Pitman arm from the relay rod. Support the rack and pinion, remove the mounting bolts, and lower the unit. Separate the intermediate shaft from the rack and pinion input shaft and remove the rack and pinion from the vehicle. To install the rack and pinion, slide the Pitman arm onto the shaft, aligning the marks, and tighten the nut to the proper torque. Raise the rack and pinion and Pitman arm into position, connecting the intermediate shaft and aligning the marks. Install the mounting bolts and tighten them to the correct torque specifications. Install the lower intermediate shaft pinch bolt and the plastic shield. Connect the power steering hose fittings and fill the power steering pump reservoir with the recommended fluid. Finally, lower the vehicle and bleed the steering system.

Start by raising the front of the vehicle and supporting it securely on jackstands.

Do not allow the steering shaft to rotate with the steering gear removed, as this may damage the airbag coil under the steering wheel. To prevent the steering shaft from turning, place the ignition key in the Lock position and remove the key, or wrap the seatbelt around the steering wheel and clip it to the buckle.
