Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Gather tools: jack, jack stands, tire pressure gauge, wheel balancer, alignment tools.

2. Inspect and Adjust Tire Pressure

Sub-steps:
- Use a tire pressure gauge to check the inflation level of each tire.
- Inflate or deflate tires to match the manufacturer's recommended pressure found on the door jamb or owner's manual.

3. Check and Balance Tires

Sub-steps:
- Remove the wheel covers or hubcaps if applicable.
- Mount the wheel on a balancing machine and spin to check for imbalance.
- Add wheel weights as necessary to balance the wheel properly, ensuring they are securely attached.

4. Align Front End

Sub-steps:
- Place the vehicle on an alignment rack or use alignment tools.
- Adjust the camber, caster, and toe angles according to the manufacturer's specifications.
- Tighten all adjustment bolts to the specified torque values.

5. Inspect Suspension and Drivetrain

Sub-steps:
- Visually inspect suspension components (control arms, bushings, shocks, etc.) for signs of wear or damage.
- Check for play in the wheel bearings and inspect driveshaft for any bends or damage.
- Replace any worn or damaged components as needed.
