Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery for safety if working on electronic components.

2. Tire Inspection and Replacement

Remove all four tires using a socket set.
Inspect each tire for:
- Tread depth (should be at least 2/32 inches).
- Uneven wear patterns indicating misalignment or suspension issues.
- Sidewall damage or punctures.
Replace any tires that do not meet safety standards. Tools Required: Socket set, tire pressure gauge Parts Required: New tires if necessary
Reinstall the tires and torque to manufacturer specifications (typically 80-100 ft-lbs).

3. Suspension Component Inspection

Visually inspect struts and shocks for leaks, dents, or damage.
Check control arms, bushings, and sway bar links for signs of wear.
Replace any damaged suspension components. Tools Required: Wrench set, jack stands Parts Required: Replacement struts, shocks, or bushings as needed
Reassemble and torque components to manufacturer specifications.

4. Alignment Adjustment

After replacing tires or suspension components, perform a wheel alignment.
Use an alignment machine to adjust toe, camber, and caster settings to manufacturer specifications. Tools Required: Alignment machine Parts Required: None
