Power Steering Pump: Reassembly

To assemble, reverse disassembly procedure. Install rotor, cam ring and vanes in respective order using match marks made during disassembly. Lubricate internal components, including "O" rings, with power steering fluid. Tighten rear housing bolts to 12 ft. lbs. (16 N.m) on 1995 models, or 18 ft. lbs. (24 N.m) on 1996 models. Ensure power steering pump shaft rotates smoothly. Check if power steering shaft preload is less than 2.2 INCH lbs. (.2 N.m). If preload is not as specified, replace power steering pump assembly.
