Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire’s pressure.
Inflate or deflate tires to the recommended pressure as per the owner's manual.

3. Wheel Balancing

Remove the wheels using a lug nut wrench.
Place each wheel on a balancing machine to identify imbalances.
Add wheel weights as necessary to achieve balance.
Reinstall the wheels and torque lug nuts to the manufacturer’s specifications (typically 100-120 lb-ft).

4. Wheel Alignment

Set up the vehicle on an alignment rack.
Adjust the toe, camber, and caster angles as per the specifications in the service manual.
Perform a road test to ensure proper alignment.

5. Inspect and Repair Drivetrain Components (if necessary)

Check the driveshaft for any signs of damage or wear.
Inspect CV joints and axles for play or damage.
Replace any damaged components and ensure all fasteners are torqued to specifications.
