Steering Gear

You should begin this repair by hoisting the car and using support equipment before uninstalling both wheels and tires. Sever the tie rod ends from steering knuckles and disconnect the intermediate shaft connecting to the Rack And Pinion. After removing the stabilizer shaft you must disconnect the power steering pressure and return hoses connected to the Rack And Pinion. Move both the power steering line hold-downs from the crossmember and also detach the brake pressure modulator valve (BPMV) bracket. Gently loosen the two rear crossmember mounting nuts (10 mm) with hand tools yet leave them in place. Separate the height sensor arm from the Control Arm while you position a utility stand to support the crossmember's front section. The j 33432-a leaf spring compressor allows you to compress the coil spring which provides enough clearance for gear removal from the crossmember. Disassemble the lower shock mounting bolts and the left front brake caliper brake pipe bracket from the crossmember and the right front brake pipe plastic hold-down. By removing the Rack And Pinion mounting bolts and nuts workers should be able to shift the Rack And Pinion through the left wheelhouse opening around the brake lines. To install the Rack And Pinion place it through the left wheelhouse opening and install the mounting bolts alongside nuts before tightening the nuts to 100 nm (74 ft. Lbs.). Put back the lower shock mounting bolts before you elevate the crossmember with a utility stand then remove the j 33432-a. Tighten all crossmember mounting nuts to 110 nm (81 ft. Lbs.) using only hand tools. Following brake pipe bracket installation on the left front brake caliper and right front brake pipe plastic hold-down attachment reinstallation comes brake bpmv bracket installment. Secure both ends of the power steering pressure hose to the Rack And Pinion but torque the fittings to 27 nm (20 ft. Lbs.) and do the same for the power steering return hose (27 Nm, or 29 ft. Lbs.). Fasten power steering hold-downs between crossmember and stabilizer shaft. Rejoin intermediate shaft to Rack And Pinion. Secure the height sensor arm to the Control Arm while also connecting the tie rod ends to steering knuckles. The process ends with wheel and tire installation followed by vehicle lowering and power steering bleeding and front wheel toe adjustment.

Install the power steering gear mounting bolts and nuts, tightening the nuts to 100 Nm (74 ft. lbs.).
