Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Tire Inspection

Sub-steps:
1. Remove hubcaps (if applicable).
2. Inspect each tire for cuts, bulges, or foreign objects embedded in the tread.
3. Measure tire pressure using a tire gauge and inflate to the recommended PSI if necessary.
4. Check tread depth using a tread depth gauge; replace tires if tread is below legal limits.

3. Wheel Balancing

Tools Required:
- Wheel balancer
Sub-steps:
1. Remove the wheel from the vehicle.
2. Mount the wheel on the balancer and spin to check for imbalance.
3. Add or adjust wheel weights as necessary to achieve balance.
4. Reinstall the wheel and torque to the manufacturer’s specifications (typically 100-120 ft-lbs).

4. Suspension Inspection

Sub-steps:
1. Visually inspect all suspension components, including control arms, bushings, and struts for signs of wear or damage.
2. Check for play in the wheel bearings by rocking the wheel back and forth.
3. Replace any worn or damaged suspension components.

5. Alignment Check

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Have the alignment checked and adjusted according to the manufacturer's specifications.
