Question 1

How to Replace the Front Rack and Pinion Steering Gear on Buick Enclave?

Accepted Answer

The first step to replace a Rack And Pinion starts with wheel security through an anti-rotation pin or steering column lock or strap setup to stop wheel movement thus protecting the sir system. Secure the Steering Wheel first before placing drain pans below the vehicle to perform maximum drawdown of power steering fluid from the power steering fluid reservoir. You must disconnect the following components from their related elements: steering knuckles from the steering linkage outer tie rods, stabilizer shaft links from the stabilizer shaft and intermediate Steering Shaft from Rack And Pinion. Begin by removing the rear propeller shaft and underbody rear side rails and continue by removing both frame brace and right side Catalytic Converter. Place adjustable jack stands beneath the vehicle at the front frame's rear side while removing the left and right front frame reinforcement mounting bolts after you install the stands beneath the left and right vehicle sides. Start the process by loosening the bolts on front frame reinforcement mounting and front frame mounting and front frame rear mounting and lower the front frame down until you have enough space to remove the Rack And Pinion. The power steering Rack And Pinion inlet and outlet hoses need separation from the Rack And Pinion after disconnecting power steering Rack And Pinion inlet and outlet pipes and removing the power steering Rack And Pinion inlet hose retaining plate bolt. Drive the Rack And Pinion out of the vehicle to the left side after unfastening left side nuts and bolts along with right side bolts. When installing the new Rack And Pinion position it on the left side of the vehicle while starting every bolt manually before completing torque specifications. The left side Rack And Pinion requires nuts and bolts installed along with 180 nm (133 lb ft) torque while right side bolts need 100 nm (74 lb ft) torque. The power steering Rack And Pinion receives its inlet and outlet hoses for connection after the inlet hose retaining plate bolt achieves 12 nm (106 lb in) torque and the inlet and outlet pipe clip bolt gets tightened to 9 nm (80 lb in). After raising the front frame until it sits 12 mm (0.5 in) above the body install both side front reinforcement bolts with 50 nm (37 lb ft) torque and the front frame rear bolts with 100 nm (74 lb ft) torque before turning the front frame bolts an additional 90 degrees. First install the front frame mounting bolts at 100 nm (74 lb ft) torque then add an additional 90 degrees rotation until achieving 50 nm (37 lb ft) for front frame reinforcement mounting bolts. Clean all remaining fluid from the components while you put the underbody rear side rails back into place. Reinstall the rear propeller shaft followed by the Rack And Pinion heat shields and right side Catalytic Converter before you install the frame brace. Connect all components including the intermediate Steering Shaft between the Rack And Pinion and the stabilizer shaft links to their attachment points at the stabilizer shaft. Also reconnect the steering linkage outer tie rods to the steering knuckles. The power steering system requires bleeding after which you measure and adjust the front toe alignment.

Question 2

How to Replace the Front Rack and Pinion Steering Gear on Buick Regal?

Accepted Answer

The first step to change the Rack And Pinion is to support and raise the vehicle before placing a drain pan underneath. The tire and wheel assembly needs removal before disconnecting the intermediate shaft from the Rack And Pinion stub shaft to prevent damage. Unbolt the intermediate Steering Shaft at its lower attachment to the Rack And Pinion stub shaft after positioning the Steering Shaft with its block tooth aligned at 12 o'clock and wheels facing forward while maintaining an ignition switch lock position. Disconnect the intermediate Steering Shaft from the Rack And Pinion stub shaft then remove both tie rod ends from the steering knuckles. The rear of the frame needs support from jackstands while frame bolts at the rear need removing but take care to maintain sufficient frame height to avoid damaging nearby engine components. After lowering the frame rear portion, technicians must eliminate the Rack And Pinion pressure line and return hose from the assembly and the magnasteer variable assist electrical connector if the vehicle has this system. The technicians should detach the Rack And Pinion's mounting hardware followed by extracting the steering unit through the left wheel opening. Sliding the new Rack And Pinion through the left wheel opening marks the beginning of installation which requires bolt and nut mounting followed by torque settings at 80 nm (59 ft. Lbs.). Check threads on Rack And Pinion pressure line and return hose then replace and lubricate o-ring seals if visible damage is detected. Secure Rack And Pinion lines to the assembly before you connect the pressure line and return line and magnasteer connector if needed. When the frame reaches its proper position install new rear frame bolts before taking out the jackstands. Install the pinch bolt when the Steering Shaft is fully in position now tighten the bolt to 47 nm (35 ft. Lbs.). The last stage involves tire and wheel reinstallation followed by drain pan removal and vehicle lowering. The Rack And Pinion system requires fluid replenishment and system bleeding before leak inspections and front-end alignment.
