Solution

1. Preparation

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

2. Inspect and Replace Tires

Inspect Tires:
- Examine all tires for uneven wear, cracks, or bulges.
- Measure tread depth using a tread depth gauge.
Replace Tires (if necessary):
- Remove wheel covers (if applicable).
- Loosen lug nuts using a socket set.
- Lift the vehicle using a jack and secure with jack stands.
- Remove the wheels and replace with new tires, ensuring the correct size and load rating.
- Torque lug nuts to manufacturer specifications (usually around 100-120 ft-lbs).

3. Perform Wheel Balance

Mount wheels on a balancing machine.
Add or remove weights to achieve proper balance.
Reinstall the balanced wheels on the vehicle.

4. Suspension Inspection and Repair

Inspect Components:
- Look for any cracked or worn bushings, shock absorbers, or struts.
Replace Worn Parts:
- If any components are worn, remove them using appropriate tools (e.g., socket set).
- Install new suspension components, ensuring they are properly torqued.

5. Wheel Alignment

Use a wheel alignment machine to measure angles.
Adjust camber, caster, and toe settings to meet manufacturer specifications.
Ensure all adjustments are locked in place and double-check alignment results.
