Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

Inspect Tire Condition
- Check for bulges, cuts, or foreign objects lodged in the tread.
- Measure tread depth using a tread depth gauge.
Replace Tires (if necessary)
- Use a jack to lift the vehicle and remove the wheel lugs with a socket set.
- Remove the old tire and mount the new tire, ensuring it is seated properly on the rim.
- Torque the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).
- Reinstall the wheel and lower the vehicle.

3. Wheel Bearing Replacement (if needed)

Remove Wheel
- Use a jack to lift the vehicle and remove the wheel.
Remove Brake Caliper and Rotor
- Unbolt the brake caliper and support it without straining the brake line.
- Remove the rotor by unscrewing the retaining screws.
Remove Wheel Hub Assembly
- Remove axle nut and bolts securing the wheel hub.
- Use a puller to remove the hub if it is stuck.
Install New Wheel Bearing
- Press the new wheel bearing into the hub assembly using a bearing press.
- Reassemble the hub assembly and reinstall the rotor and brake caliper.

4. Drivetrain Inspection and Repair

Inspect Driveshaft and Differential
- Check for any visible signs of wear or damage on the driveshaft and differential.
- Replace any worn components as necessary.
Reassemble
- Ensure all bolts are torqued to specifications and reassemble any components that were removed.
