Rotate tires if uneven wear is detected.
Inspect for any damages like bulges or cuts. Replace tires if necessary.
Tools Required: Jack and jack stands, lug wrench.

3. Wheel Alignment

Perform a four-wheel alignment using an alignment machine.
Adjust caster, camber, and toe settings to factory specifications.
Tools Required: Wheel alignment machine, torque wrench.

4. Suspension Component Inspection/Replacement

If damaged components are found, replace them. This may include control arms, struts, or bushings.
Ensure all bolts are torqued to manufacturer specifications upon reinstallation.
Tools Required: Socket set, torque wrench, possibly a spring compressor if struts are replaced.

5. Test Drive

Conduct a test drive post-repair to ensure the wandering sensation has been resolved and handling feels stable.
