• Q: How to Replace the Front Rack and Pinion Steering Gear on 2008 Buick Lucerne?

  A: Begin steering gear replacement by inserting the Steering Column anti-rotation pin (J 42640) through the column's underside to lock the Steering Column. Position the vehicle on supports before you take out the tires and wheels. Afterwards detach the Rack And Pinion's heatshield. The steering wheel should face forward and the Steering Column must be secured in toggle position before disconnecting any steering components to stop coil assembly damage. First remove the lower pinch bolt from the intermediate shaft then disconnect the shaft from the Rack And Pinion before removing the outer tie rods retaining nuts. Begin outer tie rod separation process from steering knuckles by using universal steering linkage puller (J 24319-B) before removing power steering pressure and return hoses from Rack And Pinion. For equipment with variable effort steering disconnect the electrical connector while also removing the left stabilizer shaft insulator and separating the tie rod ends from the knuckles. First disconnect Rack And Pinion mounting bolts and pull out the Rack And Pinion from the left-wheel opening. After placing the Rack And Pinion through the left wheel opening properly install the Rack And Pinion mounting bolts and torque them to 95 n.m (70 lb ft). The left stabilizer shaft insulator goes back into position while the power steering pressure and return hoses connect with 30 n.m (22 lb ft) torque. After hooking up any available variable effort steering electrical connector, install the outer tie rod to its respective steering knuckle while securing retaining nuts at 30 n.m (22 lb ft) torque with an additional 180 degrees of rotation. After connecting the intermediate shaft to the Rack And Pinion you should install and torque the lower intermediate shaft pinch bolt to 47 n.m (37 lb ft). After fitting new tires and wheels and the Rack And Pinion heatshield the vehicle should be lowered completely. You must first remove the Steering Column anti-rotation pin (J 42640) from the Steering Column before you perform the power steering system bleed and leak check and adjust the front toe.
