NUMBER: 05-05-00
GROUP: Brakes
DATE: MAY 26, 2000
SUBJECT:
Rear brake clunk or thump when brakes are applied
MODELS:
1997 - 1999 (XJ) Cherokee
OVERVIEW:
This bulletin involves installing a rear axle shaft(s).
NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH AN 8 1/4 INCH REAR AXLE.
SYMPTOM/CONDITION:
A clunk or thump may be heard coming from the rear of the vehicle when the brakes are applied on some vehicles equipped with an 8 1/4-inch rear axle.
This may be caused by an axle shaft, which does not have a correct size brake drum pilot flange.
Figure 2
DIAGNOSIS:
If the vehicle exhibits the condition, remove the rear wheels and brake drums and inspect the rear axle shafts at the center pilot for the wheel and brake
drum. There must be two separate pilot diameters on this area (See Figure 1). The outboard diameter for the wheel (2.812-2.808 inches) and the slightly
larger inner diameter to support the brake drum (2.832-2.826 inches). The brake drum pilot may be missing or may not be deep enough to support the
drum. If the drum pilot does not adequately support the drum, some movement of the drum may occur when the brakes are applied causing this noise. If
this condition is present, perform the Repair Procedure.
