Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, OBD-II scanner, torque wrench, socket set.
Instructions:
- Park the vehicle on a level surface and engage the parking brake.
- Disconnect the battery to prevent any electrical issues during the repair process.

2. Tire Inspection and Balancing

Sub-steps:
- Remove the wheels using a socket set to access the tires.
- Inspect tires for uneven wear, bulges, or foreign objects.
- If balancing is needed, mount the tire on a balancing machine and adjust weights accordingly.
- Reinstall the wheels and torque the lug nuts to the manufacturer’s specification (usually around 100-120 Nm).

3. Wheel Alignment

Instructions:
- Use an alignment machine to check the alignment settings.
- Adjust toe, camber, and caster to manufacturer specifications.
- Test drive the vehicle to ensure proper alignment.

4. Inspect Drivetrain Components

Sub-steps:
- Lift the vehicle and inspect the driveshaft and CV joints visually for cracks or excessive play.
- Replace any damaged CV joints or driveshaft components as necessary.

5. Check Engine and Transmission Mounts

Sub-steps:
- Inspect mounts for cracks or signs of wear.
- Replace any failed mounts with OEM parts to maintain proper engine and transmission alignment.

6. Examine Suspension Components

Instructions:
- Check control arms, bushings, and shock absorbers for wear or damage.
- Replace any worn suspension components with high-quality replacements.
