Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Raise the vehicle with a jack and support it on jack stands.

2. Fluid Check and Replacement

Tools Required: Socket set, fluid pump, differential fluid.
Steps:
1. Remove the differential cover bolts using the socket set.
2. Carefully remove the cover and drain the old fluid into a container.
3. Inspect the condition of the fluid; it should not be metal-shiny or burnt.
4. Clean the mating surfaces of the differential and cover using a scraper.
5. Replace the old fluid with new differential fluid as specified in the owner's manual.
6. Reinstall the cover and torque the bolts to manufacturer specifications.

3. Inspect and Replace Bearings or Gears

Tools Required: Bearing puller, torque wrench, new bearings/gears if necessary.
Steps:
1. Remove the driveshaft by unbolting it from the differential.
2. Remove the differential assembly from the housing.
3. Inspect the ring and pinion gears for wear or damage.
4. Use the bearing puller to remove any worn bearings.
5. Install new bearings and gears, ensuring proper alignment.
6. Reinstall the differential assembly and driveshaft.

4. Universal Joint Inspection

Tools Required: Socket set, grease, replacement universal joint if damaged.
Steps:
1. Inspect the universal joints on the driveshaft for wear or play.
2. If damaged, remove the old joint using the socket set.
3. Install a new universal joint, ensuring proper lubrication.
4. Reinstall the driveshaft.
