- Torque the new mount bolts to the manufacturer's specifications.

3. Check and Replace Driveshaft or CV Joints

Sub-steps:
- Inspect the driveshaft for any visible damage or imbalance.
- Check the CV joints for grease leakage or torn boots.
- If any damage is found, use a socket set to remove the driveshaft from the vehicle.
- Replace any damaged CV joints or the entire driveshaft as necessary.
- Reinstall the driveshaft and torque the bolts to specification.

4. Inspect Tires and Alignment

Sub-steps:
- Remove the tires and visually inspect for uneven wear.
- Check tire pressure and adjust to recommended levels.
- If tires show uneven wear or damage, replace them.
- Perform a wheel alignment to ensure proper handling and prevent shuddering.

5. Fuel System Inspection

Sub-steps:
- Remove the fuel filter and replace it with a new one.
