Solution

1. Preparation

Tools Required: Jack, jack stands, OBD-II scanner, torque wrench, socket set, tire pressure gauge.
Ensure vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Balancing

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Inspect each tire for uneven wear, bulges, or damage.
3. Check tire pressure using a tire pressure gauge; inflate to the manufacturer's recommended PSI.
4. If tires are worn or damaged, replace them.
5. If tires are fine, take the vehicle to a tire shop for balancing.

3. Inspect and Replace Worn Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect the CV joints and axles for any signs of damage or excessive play.
3. If damaged, remove the affected axle by unbolting it from the differential and wheel hub.
4. Replace with a new or remanufactured axle.
5. Tighten bolts to the specified torque settings.

4. Check Engine and Transmission Mounts

Sub-steps:
1. Visually inspect the engine and transmission mounts for cracks or deterioration.
2. If mounts are damaged, unbolt the mounts from the frame and engine.
3. Replace with new mounts and re-torque bolts to manufacturer specifications.

5. Driveshaft Inspection

Sub-steps:
1. Inspect the driveshaft for any signs of damage or bent sections.
2. Check for proper alignment and that the U-joints are functioning correctly.
3. If issues are found, replace the driveshaft or the U-joints as necessary.
