Replace any damaged mounts. Ensure new mounts are torqued to manufacturer specifications.

3. Check Tires

Tools Required: Tire pressure gauge
Measure tire pressure and inflate to the recommended PSI.
Inspect tires for uneven wear patterns; replace tires if necessary.
Rotate tires if uneven wear is present.

4. Examine Driveshaft and CV Joints

Tools Required: Jack and jack stands, socket set
Safely lift the vehicle using a jack and secure it on jack stands.
