Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery (if working on electronic components).

2. Tire Inspection and Replacement

Sub-steps:
1. Remove each wheel using a socket set.
2. Inspect for uneven wear; if wear is significant, replace tires with new, high-quality tires.
3. Mount the new tires, ensuring they are balanced properly.

3. Suspension Inspection and Repair

Sub-steps:
1. Inspect all suspension components for wear (bushings, struts, shocks).
2. Replace any worn components with OEM parts.
3. Reassemble suspension components and ensure all bolts are torqued to specifications (refer to manufacturer torque specifications).

4. Wheel Alignment

Sub-steps:
1. Align the vehicle using a professional alignment machine.
2. Adjust camber, toe, and caster settings to meet manufacturer specifications.
3. Perform a test drive to ensure alignment is correct.
