CORRECTIVE ACTION
45. NOISY STEERING
Step 1.
Inspect power steering belt and pump pulley for looseness or damage.
Tighten if loose and replace if damaged. (See paragraph 8-15)
Step 2.
Check power steering pump fluid level (see LO 9-2320-289-12)
Step 3.
Inspect power steering pump reservoir for air in power steering fluid. Power steering
fluid will have milky appearance if it contains air. If there is air in system, inspect
pump and hoses for leakage.

Step 4.
Inspect steering gear.
If loose, tighten mounting bolts to 75 Ib.-ft. (102 N•m).
Step 5.
Inspect power steering hoses for restrictions and to see if they are touching other
parts of the truck.
Clear restrictions or reposition hoses as required. (See paragraph 8-14)

Inspect connecting rod, pitman arm, and tie-rod ends for looseness or wear.
Adjust or replace as required. (See paragraphs 8-10, 8-11, and 8-13)
43. SLOW RETURN OF STEERING
Step 1.
Check for incorrect tire pressure. (see TM 9-2320-289-10)
Step 2.
Check for binding in steering linkage at tie-rod ends, connecting rod, and kingpins.
Lubricate (see LO 9-2320-289-12) or replace tie-rod ends (see
