Drain the power steering fluid reservoir using a clean syringe and do not reuse the fluid. Raise the front of the car and remove the front wheels, then take off the splash shield from underneath the engine. Detach the tie rod ends from the steering knuckles and, if necessary, remove the heat shield from the Rack And Pinions. Remove the steering spindle universal joint pinch bolt and disengage the spindle from the Rack And Pinions. Release the banjo bolt fasteners and remove the pressure line and return line from the Rack And Pinions, being prepared to catch any dripping fluid. Tie the hydraulic lines off to the side and, if necessary, remove the hydraulic line bracket from the power steering pump. Plug the openings in the Rack And Pinions and hoses to prevent contamination. Release the fasteners and remove the Rack And Pinions forward and down. For installation, ensure all threaded bores, bolts, nuts, splines, and mating surfaces are clean, replace the banjo bolt sealing O-rings without over-torquing the banjo bolts, and ensure the power steering fluid lines are routed without tension and with sufficient spacing to nearby components. Use new Rack And Pinions mounting bolts and tighten them in two stages, replace the steering spindle double universal joint pinch bolt(s), and use new self-locking fasteners wherever applicable. Rotate the steering wheel to check that the steering spindle and steering double universal joint do not contact the vehicle chassis or front subframe; if necessary, loosen the Rack And Pinions and rotate it in the slotted holes for better clearance. After reassembling the steering and front suspension, fill and bleed the power steering system, check for leaks, have the car professionally aligned, and carry out the steering angle sensor adjustment using a BMW scan tool.
