Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Park the vehicle on a level surface and engage the parking brake.
• Gather necessary safety equipment, including gloves and safety glasses.

2. Tire Balancing

• Sub-steps:
  1. Remove the front wheels using a lug wrench.
  2. Take the wheels to a tire balancing machine.

3. Tire Inspection and Replacement

• Sub-steps:
  1. Inspect each tire for signs of uneven wear, bulges, or foreign objects.
  2. If any tire is damaged or worn excessively, replace with a new tire of the same specifications.

4. Wheel Alignment

• Sub-steps:
  1. Use an alignment rack to check the alignment settings.
  2. Adjust camber, toe, and caster angles to meet manufacturer specifications.
  3. Test drive the vehicle to ensure proper alignment.
