Steering Gear

Start by raising and supporting a vehicle for Rack And Pinion replacement. Begin by uninstalling the stabilizer shaft before taking apart the tie rod ends connected to the steering knuckles and the steering intermediate shaft from the Rack And Pinion. A utility stand will support the frame during the process, but the frame rear bolts must be removed one by one because lowering the frame excessively poses a risk of damaging engine components. Lower the frame together with the powertrain through a utility stand and then take off the Rack And Pinion heat shield. The Rack And Pinion needs its cooler pipe and pressure hose disconnected from its steering gear before the fasteners are removed and the Rack And Pinion is extracted. Drill through the vehicle's left side wheel opening to pull out the Rack And Pinion. When installing the rack, place it through the left wheel opening to the frame and apply the bolts keeping them rust-free then tightening them to achieve 2 nm (18 inch lbs.) of torque/drag before full seating due to bolt replacement if necessary. If not, replace the fastener. Tighten each Rack And Pinion nut to 60 nm (44 ft. Lbs.) while applying 60 degrees of torque. You should place the Rack And Pinion heat shield back in position and fasten the pressure hose while tightening both fittings to 27 nm (20 ft. Lbs.) before installing the cooler pipe retaining clip. Lift the frame and powertrain assembly using a utility stand before tightening the frame rear bolts to 165 nm (122 ft. Lbs.). After steering intermediate shaft installation, you must return the stabilizer shaft and reconnect tie rod ends before lowering the vehicle. The procedure includes filling the Rack And Pinion system before performing air bleeding while performing leak tests and performing necessary toe adjustments.

Connect the power steering gear pressure hose and tighten it to 27 Nm (20 ft. lbs.), then connect the cooler pipe and tighten it to the same specification.
