Solution

1. Tire Inspection

Sub-steps:
- Visually inspect all tires for bulges, cuts, or uneven wear patterns.
- Measure tire pressure using a tire gauge and inflate to the manufacturer's specifications.
- If tires are unbalanced, take them to a tire shop for balancing.

2. Driveshaft and U-joint Inspection

Sub-steps:
- Safely lift the vehicle using jack stands and remove any protective covers if necessary.
- Inspect the driveshaft for signs of bending or damage; rotate it to check for any binding.
- Check U-joints by attempting to move them side-to-side; replace if there is excessive play.
Tools Required: Jack and jack stands, socket set.

3. Engine Mount Replacement (if needed)

Sub-steps:
- With the vehicle lifted securely, locate the engine mounts.
- Remove the bolts securing the mounts to the frame and engine.
- Replace the old mounts with new ones, ensuring they are properly aligned.
- Torque the mounting bolts to the manufacturer's specifications.
Tools Required: Socket set, torque wrench.
