TM   10-3930-638-24&P 3-23. STEERING COLUMN AND CYLINDER TROUBLESHOOTING MALFUNCTION TEST  OR  INSPECTION CORRECTIVE   ACTION 1.   EFFORT TO TURN IN ONE DIRECTION IS MORE THAN REQUIRED IN OTHER DIRECTION Disconnect horn switch (para 2-32b) to gain access to steering wheel retaining nut. Park vehicle on dry pavement and center steering wheel. Start engine and operate at a fast idle. Using a torque wrench on steering wheel retaining nut, measure and record effort required to turn steering wheel to the right. Then, center steering wheel and measure and record effort required to turn steering wheel to the left. The difference between the two torque readings should be less than 2 pound inches. If the difference between torque readings for left turn and right turn is more than 2 pound inches, steering gear is damaged or has incorrect shims installed. Repair steering gear (para 3-24b). 2.  STEERING WHEEL TURNS HARD IN BOTH DIRECTIONS Step  1. Step 2. Park vehicle on dry pavement with engine off. Turn steering wheel in both directions and check for binding or unusual noises at the steering column. a. If binding or unusual noises are detected, repair steering column (para 3-24a). b. If steering wheel turns smoothly, without binding or unusual noises, proceed to step 2. Rotate steering wheel until vehicle is fully turned (articulated) to the left. With engine off, loosen two clamps and slide cylinder guard toward front of vehicle, and disconnect hose from elbow as shown. WARNING Keep hands and feet clear of steering cylinder assembly while checking for leakage. Failure to do so could cause bodily  injury. Start engine and hold steering wheel at the full left turn position. Check for hydraulic oil leakage from the open steer- ing cylinder elbow, then stop engine. a.  Hydraulic  oil  coming  from  open  steering  cylinder elbow indicates internal steering cylinder leakage. Repair steering cylinder assembly (para 3-24d). b. If hydraulic oil does not leak from open steer- ing cylinder elbow, proceed to step 3. 3-154
