Cross-Member: All Technical Service Bulletins
Bumper Crossmember (Front) - Squeaks
NUMBER: 13-001-02
GROUP: Frame & Bumper
DATE: May 20, 2002
SUBJECT:
Squeak-Like Sound From Front Bumper
OVERVIEW:
This bulletin involves drilling holes and installing six rivets at two specified locations on the left and right side of the front bumper crossmember.
MODELS:
2002 (KJ) Liberty / Cherokee
NOTE:
THIS BULLETIN APPLIES TO VEHICLES BUILT PRIOR TO FEBRUARY 01, 2002.
SYMPTOM/CONDITION:
A customer may experience a squeak-like sound when driving slowly over driveway entrances, road bumps, or when performing parking lot maneuvers.
The squeak-like sound may occur when the vehicle body/frame is flexed (twists). This condition may occur when the front edge flange of either frame
rail rubs against the backside of the front bumper crossmember.
DIAGNOSIS:
With the vehicle stopped and in park, slowly rock the vehicle from side-to-side. Applying force to the top edge of the driver or front passenger side door
opening may be of assistance. If present, the squeak-like sound will come from behind the front bumper fascia and in the immediate area below either
front headlamp.
Another diagnostic method is to set the parking brake, start the vehicle engine, and while in park slowly turn the vehicle front wheels from side-to-side
(to flex the body) while someone listens at the front of the vehicle.
If the above condition is present perform the Repair Procedure to both the left and right side of the front bumper crossmember.
PARTS REQUIRED
REPAIR PROCEDURE:
1.
Remove the vehicle front grill and fascia. For additional disassembly and assembly instructions refer to the Frame & Bumper Section of the
appropriate 2002 Service Manual.
2.
Remove the screw used to secure the right side frame rail end cap to the front bumper crossmember. The frame rail cap covers the rectangular
access hole in the crossmember. Remove the end cap.
