Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

Inspect all tires for uneven wear and proper pressure.
- Tools Required: Tire pressure gauge, jack, jack stands, lug wrench
- Sub-steps:
  1. Remove the wheel covers or hubcaps if applicable.
  2. Use the tire pressure gauge to check PSI; inflate to manufacturer specifications if low.
  3. If tires are worn unevenly beyond acceptable limits, remove and replace with new tires.

3. Suspension Component Inspection and Repair

Examine suspension components for damage.
- Tools Required: Socket set, torque wrench, pry bar
- Sub-steps:
  1. Lift the vehicle and secure with jack stands.
  2. Use the socket set to remove any protective covers.
  3. Visually inspect struts, shocks, and bushings for wear or leaks.
  4. Replace any damaged components and torque to manufacturer specifications.

4. Wheel Alignment Adjustment

Perform a wheel alignment to correct misalignment.
- Tools Required: Alignment rack, camber/caster gauge
- Sub-steps:
  1. Drive the vehicle onto the alignment rack.
  2. Adjust the camber, caster, and toe settings according to manufacturer specifications.
  3. Test drive to ensure alignment is correct.

5. Wheel Balancing

Check and balance wheels if necessary.
- Tools Required: Wheel balancer
- Sub-steps:
  1. Remove wheels from the vehicle.
  2. Mount each wheel on the balancer and adjust weights as needed.
  3. Reinstall balanced wheels back on the vehicle.
