Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Tire Inspection and Replacement

Inspect Tires:
- Remove the wheel covers or hubcaps if applicable.
- Use a tread depth gauge to measure the tire tread. Replace any tires with tread depth below 2/32 inches.
Replace Tires if Necessary:
- Loosen wheel lug nuts slightly before raising the vehicle.
- Use a jack to lift the vehicle and then secure with jack stands.
- Remove the lug nuts completely and take off the tire.
- Install the new tire, tightening lug nuts by hand initially.
- Lower the vehicle and torque the lug nuts to the manufacturer’s specification (typically 80-100 ft-lbs).

3. Suspension and Alignment Adjustment

Inspect Suspension Components:
- Check for worn or damaged control arms, bushings, and tie rods. Replace any defective parts.
Perform Wheel Alignment:
- Take the vehicle to a professional alignment shop or use a wheel alignment tool.
- Adjust the camber, caster, and toe settings according to the manufacturer’s specifications.
