Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical shorts during repair.

2. Tire Inspection and Replacement (if needed)

Remove the wheel covers or lug nut caps.
Use a jack to lift the vehicle and support it with jack stands.
Check tire tread depth and overall condition. Replace tires if they show uneven wear or are worn beyond specifications.
Reinstall the wheels and torque to manufacturer specifications (typically 80-100 ft-lbs).

3. Suspension Component Replacement

Identify worn or damaged components (e.g., struts, springs, sway bar links).
Remove the affected components:
- For struts: detach the strut from the wheel hub and disconnect it from the upper mount. Remove the strut assembly.
- For springs: use a spring compressor to safely remove the spring from the strut assembly.
Install new components:
- Install the new strut and/or spring ensuring it is seated properly.
- Reattach all mounting hardware and torque to manufacturer specifications.

4. Alignment

After replacing suspension components, perform a wheel alignment to ensure proper handling and tire wear.
Adjust toe, camber, and caster angles according to manufacturer specifications.

5. Final Inspection

Re-check all installed components for tightness and proper installation.
Reconnect the battery and clear any error codes with the OBD-II scanner.
