OVERVIEW:
This bulletin involves the adjustment, or possible replacement, of the front skid plate.
MODELS:
| 2002 | (KJ) | Liberty |
NOTE: THIS BULLETIN APPLIES TO VEHICLES BUILT PRIOR TO AUG. 31, 2001 (MDH 0831XX).
SYMPTOM/CONDITION:
The vehicle may exhibit a creak-like sound that originates from the front end of the vehicle. This creak-like sound may occur when the vehicle operator either applies the brakes at slow speeds, or when a slow speed turn is made (similar to what may occur during a parking lot maneuver). In a few instances the condition has been described as a pop-like sound.
The technician may erroneously diagnose the cause of this condition as a brake or suspension component.
DIAGNOSIS:
Determine if the left forward corner of the front skid plate has made contact with the front crossmember. Refer to the figure below for illustration of the possible contact area. If evidence of contact is present perform the Repair Procedure.

REPAIRPROCEDURE:
- Loosen, but do not remove, the four skid plate attaching bolts.
- Slide the front skid plate as far to the right (passenger side) of the vehicle as is possible. While holding the skid plate in place, tighten the four attaching bolts.

- If a clearance of 3.1 mm (1/8 in.) or more is now present between the front skid plate and the front crossmember, tighten the front skid plate attaching bolts to 61 Nm (45 ft. lbs.). A new front skid plate is not required.
- If the clearance between the front skid plate and front crossmember is less than 3.1 mm (1/8 in.), install a new front skid plate.
- Position the new front skid plate to right side and tighten the front skid plate attaching bolts to 61 Nm (45 ft. lbs.).
NOTE: THE TECHNICIAN SHOULD BE AWARE THAT WHEN A FRONT SKID PLATE IS INSTALLED FOLLOWING ANY SERVICE ACTIVITY, THE SKID PLATE SHOULD BE POSITIONED AS FAR TO THE RIGHT SIDE OF THE VEHICLE AS IS POSSIBLE. THIS SHOULD HELP PREVENT POSSIBLE CONTACT BETWEEN THE FRONT SKID PLATE AND THE FRONT CROSSMEMBER.
