Differential Carrier: Service and Repair
Differential Carrier Inspection Procedures
Rear Axle Total Backlash
Fig. 2 Checking Rear Axle Total Backlash
NOTE If vehicle vibrates and has a booming sound due to system driveline imbalance, total axle backlash should be checked as follows:
1. Place gearshift in neutral, apply parking brake, then raise and support vehicle.
2. Manually turn propeller shaft clockwise as far as it will go and scribe mating mark on companion flange dust cover and differential carrier.
3. Manually turn shaft counterclockwise as far as it will go and measure movement of mating marks.
4. If total axle backlash is less than 0.2 inch (5 mm), backlash is satisfactory.
5. If backlash is more than 0.2 inch (5 mm), refer to Transmission and Drivetrain/Drive Axles, Bearings and Joints/Axle Bearings/Adjustments.
Gear Oil Level Check
1. Remove filler plug and check oil level.
2. If oil level reaches bottom of filler plug hole, oil level is satisfactory.
3. If level does not reach bottom of filler plug hole, fill differential with MOPAR Hypoid Gear Oil API classification GL-5 or equivalent.
Rear Wheel Bearing Rotation Sliding Resistance Check
Fig. 4 Rear Wheel Bearing Rotation Sliding Resistance Check
1. Raise and support vehicle.
2. Disconnect driveshaft at companion flange, refer to Transmission and Drivetrain/Drive/Propeller Shafts, Bearings and Joints/Service and
Repair.
3. Remove caliper assembly and suspend with wire.
4. Attach a spring balance to hub bolt, then pull balance at a right angle to bolt. Measure rotation starting torque.
5. If rotation starting torque is less than 6 lb-in, bearing is satisfactory.
6. If rotation starting torque is more than 6 lb-in, ensure tightening torque of axle shaft companion flange is 116-159 lb-ft, on Eagle Talon and 137
lb-ft, on Stealth models less turbo or 188-217 lb-ft, on Stealth models with turbo. If torque is satisfactory, replace wheel bearing.
Limited-Slip Differential Check
1. Block front wheels and place shift lever in neutral.
2. Release parking brake completely, then raise rear wheels and support on jack stands.
3. Disconnect propeller shaft from differential.
4. Rotate one wheel slowly, ensure wheel on opposite side turns in the same direction.
5. If wheel turns in the opposite direction, replace viscous unit.
