Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Inspect Differential

Remove the differential cover using a socket set.
Check for metal shavings or debris in the fluid.
If fluid is low, top off with manufacturer-recommended fluid.
Replace the differential fluid if contaminated or if it has not been changed per maintenance schedule.

Remove the rear wheels and drums or rotors.
Inspect the axle bearings for any signs of wear or excessive play.
Replace any damaged bearings with new ones, ensuring proper lubrication.

4. Check Drive Shaft

Inspect the drive shaft for any visible signs of damage or imbalance.
Ensure all U-joints are properly lubricated and free from play.
