Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during electrical inspections (if applicable).

2. Tire Inspection and Replacement

Inspect Tires: Check for uneven wear, damage, or low tread depth.
Replace Tires: If necessary, remove the wheels using a socket set. Install new tires according to the manufacturer's specifications.

3. Wheel Alignment

Perform Alignment: Use a wheel alignment machine. Adjust camber, caster, and toe angles to factory specifications. Torque specifications should follow the manufacturer's guidelines.

4. Suspension Component Inspection and Replacement

Inspect Components: Check for play or damage in struts, shocks, and bushings.
Replace Worn Parts: If any components are damaged, remove them using a socket set. Install new suspension parts and torque to specifications.

5. Steering Component Inspection and Replacement
