Inspect steering shaft couplings and flexible coupling for looseness and wear. Tighten nuts and bolts if loose. Repair steering shaft (see paragraph 8-3) or replace fIexible coupling if worn. Inspect upper ball joints for wear (Ml 009 only), Replace ball joints if worn. (See paragraph 6-12) Adjust pitman shaft preload and bearing preload of power steering gear. (See paragraph 8-4) Disconnect power steering pump-to-power steering gear line at power steering gear. Check for worn power steering gear check valve. Replace power steering gear check valve if worn. (See paragraph 8-4) Bleed power steering system. (See TM 9-2320-289-20) Adjust power steering gear bearing preload. (See paragraph 8-4) Check for damaged or worn power steering gear.

Check alinement of power steering gear to steering column. Check to see if flexible coupling is rubbing against power steering gear adjuster plug. Adjust position of steering column if not in line with steering gear. Loosen pinch bolt of flexible coupling and assemble so that flexible coupling does not rub against power steering gear adjuster plug. Tighten pinch bolt to 30 lb.-ft. (41 N.m). Adjust pitman shaft preload and bearing preload of power steering gear. (See paragraph 8-4) Perform Mechanical Troubleshooting malfunction #45. Disassemble power steering gear (see paragraph 8-4) and check for sticking or plugged spool valve. Replace spool valve if sticking or plugged. Remove, disassemble, and inspect steering column.
