Remove wheel covers if present and inspect tires for uneven wear, cracks, or bulges.
Use a tire pressure gauge to check and adjust tire pressures to manufacturer specifications.
Balance tires if necessary.

3. Suspension Component Inspection

Lift the vehicle using a hydraulic jack and secure it on jack stands.
Visually inspect shocks and struts for leaks or physical damage.
Check all suspension bushings for cracking or separation; replace if necessary.

4. Wheel Alignment

If necessary, perform a wheel alignment using an alignment machine, following manufacturer specifications.
Adjust camber, caster, and toe settings as required.

5. Replace Worn Components

If any suspension component is found to be worn or damaged, replace it with OEM or quality aftermarket parts.
Follow manufacturer torque specifications when reinstalling components.

6. Test Drive

After repairs, lower the vehicle and take it for a test drive to ensure vibrations are resolved.
