Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Safety gear should include gloves and safety glasses.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection

Tools Required: Tire pressure gauge, jack, jack stands
Lift the vehicle using a jack and secure it with jack stands.
Check each tire for proper inflation and inspect for any bulges, cuts, or uneven wear.
Rotate or replace any damaged tires as necessary.

3. Wheel Bearing Inspection

Tools Required: Socket set, torque wrench
Remove the wheel to access the hub assembly.
Spin the hub to check for smoothness; listen for any grinding or noise.
If the bearing feels rough or has play, remove the hub and replace the wheel bearing.

4. Differential Fluid Check

Tools Required: Socket set, fluid pump
Locate the differential fill plug and remove it.
Check the fluid level; if low, add the manufacturer-recommended differential fluid until it reaches the fill hole.
If the fluid appears dirty, perform a differential fluid change.

5. Driveshaft and CV Joint Inspection

Tools Required: Pliers, screwdriver
Inspect the driveshaft for signs of wear or damage, including any play or looseness.
Check CV joints for torn boots or grease leaks.
Replace any damaged components as necessary, ensuring all fasteners are torqued to specifications.
