SYMPTOM/CONDITION
Some 1984 - 1989 Jeep Cherokee, Wagoneer, and Comanche may exhibit a popping/snapping type noise in the front end. The noise can occur when
driving on rough roads and while turning.
DIAGNOSIS
The popping/snapping noise may be caused by a worn track bar ball stud, or a loose track bar-to-frame rail bracket. With time, the layers of metal at the
bracket mounting point may "iron" themselves together, creating clearance between the bracket and frame rail.
FIGURE 1
The following repair procedure corrects a loose track bar bracket condition.

SERVICE MANUAL HAVE BEEN UPDATED. PLEASE NOTE THE REVISED TORQUE INFORMATION (FIGURE 1) IN THE
APPROPRIATE MANUALS.
REPAIR PROCEDURE
1.
Raise the vehicle on a hoist for inspection.
