Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench, and torque wrench.
Sub-steps:
1. Check the tire pressure and inflate to the recommended PSI if low.
2. Inspect each tire for uneven wear, bulges, or damage.
3. If tires are worn unevenly, replace them with new tires of the same specifications.
4. After installing new tires, torque the lug nuts to the manufacturer’s specifications (typically 76 ft-lbs).

3. Wheel Bearing Replacement (if necessary)

Tools Required: Socket set, bearing puller, torque wrench, and grease.
Sub-steps:
1. Raise the vehicle and remove the wheel for access.
2. Remove the brake caliper and rotor to expose the wheel hub.
3. Use a bearing puller to remove the old wheel bearing from the hub assembly.
4. Clean the hub and install the new wheel bearing, ensuring it is properly seated.
5. Reassemble the brake rotor, caliper, and wheel.
6. Repeat for the opposite side if required.

4. Drivetrain Inspection and Repair (if necessary)

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Inspect the driveshaft and differential for any signs of wear or damage.
2. Tighten any loose bolts to manufacturer specifications.
3. Replace any damaged components as necessary.
