Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Engine Mounts (if needed)

Tools Required: Socket set, torque wrench
Sub-steps:
1. Locate the engine mounts and visually inspect for cracks or excessive wear.
2. If damaged, remove the bolts securing the engine mount to the engine and chassis.
3. Replace with new engine mounts, ensuring they are positioned correctly.
4. Torque the bolts to the manufacturer's specifications.

3. Wheel and Tire Inspection

Tools Required: Tire pressure gauge, socket set
Sub-steps:
1. Check tire pressure and inflate to the recommended level.
2. Inspect tires for uneven wear; replace if necessary.
3. If tires are worn, remove them and install new tires, ensuring proper alignment and balance.

4. Examine and Replace Driveshaft & CV Joints (if needed)

Tools Required: Socket set, CV joint puller
Sub-steps:
1. Lift the vehicle and secure it with jack stands.
2. Inspect the driveshaft for any visible damage or excessive play.
3. Remove the driveshaft from the vehicle and inspect the CV joints.
4. Replace any damaged components and reinstall the driveshaft, ensuring proper torque specifications are followed.

5. Check Fuel System

Tools Required: Fuel pressure gauge
Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "ON" position without starting the engine and check the fuel pressure.
3. If pressure is low, inspect the fuel pump and filter, replacing them as necessary.
