Steering Gear

A Rack And Pinion replacement requires suspension of the vehicle followed by tire removal. The first step requires disconnecting the tie rod ends from their position on steering knuckles as well as the separation of the intermediate shaft from the power Rack And Pinion. Extract the stabilizer shaft and power steering pressure and return hoses as well as the power steering line hold-downs from the crossmember. You need to start by removing the brake pressure modulator valve (BPMV) bracket then the two front crossmember mounting nuts. After that focus only on loosening the two rear crossmember mounting nuts while leaving them in place. Remove the height sensor arm from its connection to the Control Arm before using a utility stand to support the crossmember's front end. Lowering the coil spring with the j 33432-a (Leaf Spring Compressor) device allows the technician to extract the crossmember. Start work by unbolting the lower shock mounting bolts followed by removal of the left front brake caliper brake pipe bracket and right front brake pipe plastic hold-down. Move the Rack And Pinion mounting bolts and nuts out before guiding the Rack And Pinion through the left wheelhouse opening around brake lines. Insert the Rack And Pinion through the left wheelhouse opening and install mounting bolts and nuts which need tightening up to 100 nm (74 lb ft). Lower shock mounting bolts are reinstalled while using a utility stand to lift the crossmember next the removal of j 33432-a. Install crossmember mounting nuts before tightening them to 110 nm (81 lb ft) and reinstall the brake pipe bracket for the left front brake caliper and plastic brake pipe hold-down for the right front brake pipe. Route the power steering pressure hose and return hose to the Rack And Pinion then apply 27 nm (20 lb ft) of fitting torque and secure the crossmember hold-downs. Safely place the stabilizer shaft and intermediate shaft on the Rack And Pinion while reattaching the height sensor arm to its Control Arm. Bleed the power steering system after reattaching the steering knuckles to tie rod ends and replacing tires and wheels and lowering the vehicle. Front wheel toe must then be adjusted.
