Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Make sure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves for protection.

2. Tire Inspection and Service

Sub-steps:
- Remove the wheel covers or hubcaps if applicable.
- Check tire pressure using a tire pressure gauge and inflate to the manufacturer's recommended PSI.
- Inspect tires for uneven wear patterns; consider rotating or replacing tires if necessary.
- Balance the tires using a tire balancing machine if they are found to be out of balance.
Tools Required: Tire pressure gauge, floor jack, jack stands, tire iron, wheel balancer.

3. Mount Inspection and Replacement

Sub-steps:
- Visually inspect engine and transmission mounts for cracks or wear.
- Lift the vehicle and secure it with jack stands.
- If mounts are damaged, remove the old mounts by unbolting them from the engine and chassis.
- Install new mounts, ensuring they are properly aligned and torqued to manufacturer specifications (usually around 40-60 ft-lbs).
Tools Required: Socket set, torque wrench.

4. Driveshaft/CV Joint Inspection

Sub-steps:
- Inspect the driveshaft for any visible signs of damage or play.
- Check CV joints for torn boots or grease leaks; replace if necessary.
- If replacing, remove the driveshaft by unbolting it from the differential and transmission, then install the new driveshaft.
Tools Required: Socket set, pry bar.
