Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Tools Required: Floor jack, jack stands, torque wrench, OBD-II scanner, basic hand tools.

2. Inspect and Replace Tires

Check tire pressure and inflate to manufacturer specifications.
Inspect tire tread for uneven wear; replace if necessary.
Tools Required: Tire pressure gauge, tire iron.
Safety Warning: Always use jack stands when lifting the vehicle.

3. Check and Replace Wheel Bearings

Lift the vehicle and remove the wheel to access the hub assembly.
Spin the wheel and listen for grinding or humming sounds indicating a bad bearing.
If necessary, replace the wheel bearing by removing the hub and pressing in a new bearing.
Torque the wheel nut to the manufacturer’s specification.
Tools Required: Socket set, bearing puller, torque wrench.

4. Inspect and Repair Drivetrain Components

Inspect the driveshaft for any signs of damage or wear.
Check CV joints for tears or leaks in the rubber boots.
If damaged, replace the driveshaft or CV joint as needed.
Tools Required: Socket set, pry bar, torque wrench.

5. Differential Fluid Change

Drain the differential fluid and inspect for metal shavings or debris.
Replace with manufacturer-recommended fluid and refill to the correct level.
Tools Required: Socket set, fluid pump, differential fluid.
Safety Warning: Allow the differential to cool before opening.
