Sub-steps:
- Check tire pressure using a tire pressure gauge; inflate to recommended specifications.
- Visually inspect tires for uneven wear patterns or damage.
- Rotate tires if uneven wear is detected.
Tools Required: Tire pressure gauge, impact wrench (for rotation)

3. Wheel Alignment and Balance

Sub-steps:
- Use an alignment machine to check the alignment settings.
- Adjust camber, caster, and toe settings as necessary.
- Balance the wheels using a wheel balancer; add weights if needed.
Tools Required: Alignment machine, wheel balancer

4. Examine Driveshaft

Sub-steps:
- Inspect the driveshaft for visible signs of damage or bending.
- Check the mounting brackets and ensure they are securely fastened.
- Replace any damaged components.
Tools Required: Socket set, torque wrench

5. Check Engine and Transmission Mounts

Sub-steps:
- Inspect mounts for cracks, excessive wear, or deterioration.
- If damaged, remove the old mounts and install new ones.
- Ensure all bolts are torqued to manufacturer specifications.
Tools Required: Socket set, torque wrench

6. Inspect Universal Joints (U-Joints)

Sub-steps:
- Check for play in the U-joints by moving the driveshaft up and down.
- Replace any worn or damaged U-joints.
Tools Required: Grease gun (for lubrication), socket set
