Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove all four tires using a socket set.
2. Inspect tires for uneven wear, bulges, or damage. Rotate or replace tires if necessary.
3. Reinstall tires and torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).
4. Check and adjust tire pressure to the recommended level (usually around 32-35 PSI).

3. Wheel Balancing

Sub-steps:
1. Mount the tire on a wheel balancer.
2. Spin the tire to identify any imbalances.
3. Add wheel weights as necessary to achieve balance.
4. Reinstall balanced tires on the vehicle.

4. Suspension and Alignment Check

Sub-steps:
1. Inspect all suspension components for wear, including bushings and struts.
2. Replace any worn or damaged parts as needed.
3. Perform a four-wheel alignment using an alignment machine to ensure proper settings.

5. Wheel Bearing Inspection

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Grab the wheel at 12 and 6 o'clock position and check for play.
3. If excessive play is detected, remove the wheel and hub assembly to replace the wheel bearing.
4. Follow the specific guidelines for bearing replacement in the service manual.
