2. Inspect control arms and bushings for cracking or excessive wear; replace if necessary.
3. Check alignment settings and adjust if they are out of specification.

4. Tire Inspection and Adjustment

Sub-steps:
1. Check tire pressure and adjust to recommended levels (typically around 42 psi for Model 3).
2. Inspect tires for uneven wear patterns; replace tires if tread depth is significantly worn.
3. Perform a wheel alignment to ensure proper handling.

5. Reassemble and Test

Sub-steps:
1. Reattach any panels or covers removed during inspection.
2. Reconnect the battery.
3. Test drive the vehicle to assess steering feel and handling.
