Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working.

2. Inspect Tires

Remove wheel covers or hubcaps if necessary.
Check tire pressure using a tire pressure gauge and inflate to manufacturer specifications.
Examine tires for signs of uneven wear; replace any damaged tires.

3. Check Wheel Bearings

Lift the vehicle using a jack and secure it with jack stands.
Grasp each wheel at the 12 and 6 o'clock positions and shake it to check for play.
If play is detected, remove the wheel and inspect the bearing for damage.

4. Inspect Differential

Locate the differential cover and remove it using a socket set.
Inspect the fluid for metal shavings or contamination.
If fluid is low, replenish with the manufacturer-recommended gear oil and replace the differential cover.

5. Test Drive

Reassemble any components removed during inspection.
Reconnect the battery, start the vehicle, and take it for a test drive.
Listen for any remaining noises and check if the issue has been resolved.
