• Q: How to Replace the Front Rack and Pinion Steering Gear on 2007 Buick Terraza?

  A: To change the Rack And Pinion, make sure that the front wheels are straight and Steering Column is locked before disconnecting any of the parts in order to prevent misalignments and damage to the sir coil assembly. Start with the rotation of the Steering Wheel to the forward position, locking it, and removing the ignition key. Raise and support the vehicle, and remove the front tire and wheel assemblies, as well as the stabilizer shaft. Loosen the outer tie rod castle nuts without using a pickle fork or wedge tool to avoid the destruction of the seal or bushing. Separate through (J 24319-B) the tie rod ends from the steering knuckles to move the intermediate shaft seal to access the Rack And Pinion pinch bolt. To remove the pinch bolt and separate the intermediate shaft from the Rack And Pinion, you need to carefully ensure that you do not lower the rear end of the frame too much due to damage to engine components. Lay down a jack stand on the rear of cradle support, unbolt the two rear cradle support bolts, and drop the rear of the cradle support for clearance. Unfasten the two Rack And Pinion heat shield bolts and remove the shield, disconnect the Rack And Pinion inlet pipe/hose and the Rack And Pinion cooler pipe/hose, and remove the o-ring seals, discarding them. Remove the Rack And Pinion mounting nuts and bolts and extract the Rack And Pinion through the left side entry wheel. For installation, insert the new Rack And Pinion through the left side wheel opening, make sure that mounting nuts and bolts are kept clean and free from rust, and have produced 2 n.m (18 lb in) of torque to the autres, before seating; otherwise, replace them. Tighten the Rack And Pinion nuts and bolts to 60 n.m (44 lb ft) with an additional 60 degrees. You have to join the Rack And Pinion inlet pipe/hose and Rack And Pinion cooler pipe/hose with new o-ring seals with the fitting tightened to 27 n.m (20 lb ft). Install back the Rack And Pinion heat shield and tighten the bolts to 14 n.m (124 lb in). Raising the rear of the cradle support with the jack stand, install the two rear cradle support bolts at 165 n.m (122 lb ft) before releasing the jack stand. Align the intermediate shaft to the Rack And Pinion, and tighten the pinch bolt to 48 n.m (35 lb ft). Install the outer tie rod ends into the steering knuckles and install outer tie rod ends castle nuts so that 2.5-4.5 Tie Rod End threads extend beyond the tie rod nut nylon, then tighten the castle nuts to 30 n.m (22 lb ft) + 120 degrees flats (2). Replace the shock absorber, the front tire and wheel assemblies, lower the vehicle, recharge and bleed the system of air and inspect and adjust the front toe as necessary.
