Front Hub - Squeak Or Creak Noise
NUMBER: 02-05-99GROUP: Suspension
DATE: June 11, 1999
SUBJECT:
Squeak Or Creak From Front Wheel Area At Low Speeds.
OVERVIEW:
This bulletin involves installing a new hub/bearing assembly.
MODELS:
1997 - 1999 (AN) Dakota
1999 (DN) Durango
NOTE:
THIS BULLETIN APPLIES TO 4X2 VEHICLES.
SYMPTOM/CONDITION:
A squeak or creak can be heard coming from the front wheel area while driving slowly and brakes not applied. In some cases, a slight brake pedal pulsation might be felt.
DIAGNOSIS:
1. Raise the vehicle on a hoist.
2. Remove both front wheel/tire assemblies.
3. Remove the spindle nut cotter pin and washer.
4. Check the spindle nut retaining torque. The nut should be tightened to 271 N.m (200 ft. lbs.).
NOTE:
IF THE NUT IS TORQUED TO LESS THAN 54 N.m (40 ft. lbs.), PERFORM THE REPAIR PROCEDURE.
5. Inspect the steering knuckle brake caliper/pad support rail for wear in the location where the brake shoes rest on the rail (Figure 1). If the wear is greater than 1.5 mm (0.060 in.) deep from the original surface, the steering knuckle must be replaced. Refer to the 1999 Dakota Service Manual (Publication No.81-370-9110), pages 2-8 or 2-16 and 2-17 for information regarding steering knuckle service.
6. Clean master cylinder reservoir and filler caps.
7. Remove the reservoir filler cap and remove approximately 1/4 of the fluid from the reservoir. Use a clean suction gun or similar device to remove the brake fluid.
8. Bottom the caliper pist6ns in the caliper bores using a large C-clamp. Position the C-clamp frame on the rear of the caliper and clamp screw on the outboard brake shoe.
9. Remove the caliper slide pins.
10. Remove caliper from steering knuckle.
CAUTION:
DO NOT ALLOW THE CALIPER TO HANG BY THE BRAKE HOSE. USE A HANGER TO SUPPORT THE CALIPER.
11. Secure a dial indicator to the steering knuckle Position the tip of the dial indicator onto the hub/bearing assembly wheel-mounting surface just outside of the wheel stud circumference (Figure 2).
12. Zero the dial indicator. Then, slowly rotate the hub/bearing assembly while recording the runout measurement.
13. If the runout measurement exceeds 0.1 mm (0.004 in.), perform the following Repair Procedure. If the runout measurement is less than 0.1 mm (0.004 in.), further diagnosis is required. Refer to the appropriate Service Manual, Groups 02, 05, and 22 for information regarding front suspension, brakes, or tire/wheel diagnosis.
NOTE:
THE DIAGNOSIS SHOULD BE PERFORMED TO BOTH RIGHT AND LEFT SIDES OF THE VEHICLE. ONLY PERFORM THE REPAIR PROCEDURE TO HUB/BEARING ASSEMBLIES THAT EXCEED 0.1 MM (0.004 IN.) RUNOUT.
