Front Caliper Mounting/Steering Knuckle - Thread Repair
NUMBER: 05-03-99
GROUP: Brakes
EFFECTIVE DATE: Apr. 23, 1999
SUBJECT:
Front Brake Caliper Mounting To Steering Knuckle Thread Repair
OVERVIEW:
This bulletin involves repair of the threads on the steering knuckle or brake caliper mounting adapter that are used to install and retain the front brake
caliper housing in its correct operating location.
MODELS:
1986 - 1999 (AN) Dakota
1998 - 1999 (DN) Durango
DISCUSSION:
A Brake Knuckle Thread Repair Kit has been developed to repair stripped threads on the front brake caliper mounting attachment making it no longer
necessary to replace the front steering knuckle/brake caliper mounting adapter when encountering stripped threads. The following information provides
the repair procedure for using the Brake Knuckle Thread Repair Kit.
DIAGNOSIS:
1.
Place the vehicle on an appropriate hoist.
2.
Remove the front tire/wheel assembly.
3.
Remove the brake caliper housing assembly by loosening the mounting bolts.
NOTE:
IF HIGH TORQUE IS ENCOUNTERED DURING THE MOUNTING BOLT REMOVAL, IT IS LIKELY THAT THREAD DAMAGE WILL
OCCUR OR HAS OCCURRED.
4.
Remove the caliper housing assembly and hang the housing on the frame of the vehicle using an appropriate wire hanger.
NOTE:
DO NOT ALLOW THE CALIPER HOUSING TO HANG BY ITSELF FROM THE BRAKE HOSE AS DAMAGE TO THE HOSE MAY
RESULT.
5.
If the vehicle has a bolt-on brake caliper mounting adapter, remove the adapter. If the brake caliper mounts directly to the steering knuckle,
remove retainers on the wheel studs and remove the rotor.
6.
Inspect the mounting bolts and knuckle threads for damage. If either is damaged, it is likely that damage to the other has occurred as well. If
damage has occurred to the threads in the form of knicks, thread pulling, or cross-threading, perform the Repair Procedure.
