Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Pressure Check

Use a tire pressure gauge to measure each tire's pressure.
Inflate or deflate tires to the manufacturer's specifications.

3. Tire Inspection and Replacement

Remove each wheel using a lug wrench.
Inspect the tires for uneven wear or damage; replace if necessary.
If tires are in good condition, reinstall them and torque the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).

4. Wheel Alignment

Use an alignment machine to check the alignment settings.
Adjust the camber, caster, and toe as needed to meet manufacturer specifications.
Tighten all adjustment bolts according to the specified torque values.

5. Suspension Inspection and Repair

Inspect struts and shocks for leaks and any signs of wear.
Replace any damaged struts or shocks with OEM or high-quality aftermarket parts.
Check the condition of suspension bushings and replace any that are cracked or worn.

6. Wheel Balancing

Remove the wheels and mount them on a wheel balancing machine.
Add weights as necessary to achieve proper balance.
Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications.
