CORRECTIVE ACTION
STEERING
48. HARD STEERING
step 1. Inspect all hydraulic lines and hoses for leaks.
Tighten loose fittings and replace leaking lines (chapter 3, section X).
step 2. Inspect steering linkage for binding, damage, and improper lubrication.
a. Repair or replace binding or damaged linkage (chapter 3, section X).
b. Lubricate linkage (LO 9-2320-272-12).
step 3. Inspect steering knuckles for binding. Raise front wheels off ground. Disconnect drag link at
pitman steering arm (para. 3-227 or 3-228). Turn wheels from side to side to determine
binding.
Notify DS maintenance if wheels do not turn from side to side without binding.
step 4. Check spring U-bolts for tightness.
Tighten U-bolt(s) 350-400 lb-ft (475-542 Nm).
step 6. Check front wheel alignment.
a. Check front tires for underinflation and uneven tire pressure. Inflate tires to proper
pressure (TM 9-2320-272-10).
b. Adjust alignment to specifications (para. 3-152).
END OF TESTING!
49. VEHICLE WANDERS OR PULLS TO ONE SIDE
Step 1. Check front tires for underinflation and uneven tire pressure.
Inflate tires to proper pressure (TM 9-2320-272-10).
Step 2. Check tires for uneven wear (indicates improper wheel alignment).
Adjust front wheel alignment (para. 3-152).
Step 3. Check for dragging brakes. Raise wheels off ground. Spin wheels by hand. Wheels should
turn with slight drag when properly adjusted.
Refer to compressed air and brake system troubleshooting (table 2-4, malfunction 4).
Step 4. Check wheel bearings for proper adjustment and damage. Raise wheels off ground. Use
prybar to lift up on bottom of tire. Excessive play indicates improper adjusted or damaged
bearings.
a. Adjust wheel bearings (para. 3-225).
b. Replace damaged bearings (para. 3-223, 3-224, 3-225, 3-460, or 3-461).
c. Check that tires are properly inflated (TM 9-2320-272-10).
Step 5. Inspect steering assist cylinder for damage and improper adjustment.
Replace or adjust steering assist cylinder (para. 3-233).
Step 6. Inspect tie rod for looseness and damage.
Tighten or replace tie rod (para. 3-163).
Step 7. Check for loose steering gear mounting bolts.
Tighten mounting bolts 260-280 lb-ft (353-380 N-m).
