• Q: How to replace the Rack and Pinion steering gear on 2004 Buick LeSabre?

  A: Start the Rack And Pinion replacement by locking the steering column using the steering column anti-rotation pin (J42640). First raise the vehicle and implement support before you can remove tires and wheels and the Rack And Pinion heatshield. Prior to disconnecting either the steering column or intermediate shaft maintain a secure lock position and straight wheel alignment to avoid breaking either component. Begin by removing the Rack And Pinion lower pinch bolt coupling then disconnect the intermediate shaft to its steering gear. Use the universal steering linkage puller (J24319-B) to disconnect the outer tie rods from steering knuckles after eliminating the retaining nuts. Disconnect power steering pressure and return hoses from the Rack And Pinion alongside disconnecting variable effort steering electrical connector when present. Start by removing the left stabilizer shaft insulator followed by separating tie rod ends from the knuckles together with the removal of Rack And Pinion mounting bolts. Follow this step to draw the Rack And Pinion from the left wheel opening and transfer outer tie rods when replacing the Rack And Pinion. To install the Rack And Pinion you must put it through the left wheel opening before securing its mounting bolts to 95 nm (70 ft. Lbs.). After installing the left stabilizer shaft insulator reconnect the power steering pressure return hoses with a torque of 30 nm (22 ft. Lbs.). After connecting the electrical variable effort steering connector when present, install the outer tie rods onto the steering knuckles securing each nut at 70 nm (52 ft. Lbs.). Attach the intermediate shaft to the Rack And Pinion then apply a torque of 45 nm (33 ft. Lbs.) when tightening the lower pinch bolt. Use the following steps to reinstall tires and wheels then lower the vehicle and remove the pin (J42640) before bleeding the power steering and inspecting for leakage before front toe adjustment.
