To take out the rack and pinions, disconnect the cable in the negative terminal of the battery at first. Disconnect the ends of the tie-rods of the steering knuckles, with an Allen wrench to hold the stud in case the ballstud spins with the nut. Disconnect the lower control arm at the steering knuckle, and seal off the extremities to prevent loss and contamination of the fluid. Other models could contain a sheetmetal shield that is held by bolts that must be removed to access the fittings. Then, undo the mounting throughbolt of the rear engine and prop the crossmember using a floor jack. Unscrew the fasteners on the lower mount, and re-screw the upper mounting bolts, and drop the crossmember, with jackstands on each side. Be careful since the crossmember is very heavy and it should be supported by the jack. Disassemble the shield when fitted and the three rack and pinions fitting bolts and then lift the rack and pinions off the crossmember and out of the car. To install, go in reverse of the steps during removal, but make sure to line the matchmarks when hooking the rack and pinions input shaft up to the intermediate shaft U-joint. Install a fresh banjo bolt and sealing washers to the power steering pressure line, check all fasteners to the correct torque values and pour in the proper fluid in the power steering reservoir. Last but not least, drain the power steering hydraulic system and ensure a front-end check-up and adjustment when needed.
