ENGINE (SALES CODES EVA OR EVC) AND BUILT PRIOR TO OCTOBER 10, 2002 (MDH 1010XX), AND INTERNATIONAL VEHICLES EQUIPPED WITH A 4.0L ENGINE (SALES CODE ERH) AND BUILT PRIOR TO FEBRUARY 02, 2003 (MDH 0202XX).
SYMPTOM/CONDITION:
The customer while driving may experience a moan or whine-like sound when turning.
The condition may occur when either a left or right turn is made.
DIAGNOSIS:
1. With the transmission in park and the parking brake set, start the vehicle engine.
2. Slowly turn the steering wheel in one direction and then in the other direction.
3. If a loud moan or whine-like sound occurs during step 2, inspect the low pressure outlet hose and high pressure inlet hose for possible hose contact in the area of the steering gear assembly (Fig. 1).
4. If hose contact is present between the low and high pressure power steering hoses, perform the Repair Procedure.
REPAIR PROCEDURE:
1. Clean the top of the power steering gear assembly where the hose connections are located.
2. Slightly loosen the low and high pressure power steering hoses at their connection to the power steering gear assembly.
3. Position each hose so that no contact between the two hoses is present. Maintain a minimum distance of 3.2 mm (0.125 inches) between the two hoses. Do not separate the two hoses too far or possible hose contact with other vehicle components (i.e. air box snorkel) may occur. (Fig. 2)
4. Tighten both hose connections to 22.5 Nm (17 ft. lbs.).
