Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety during the repair.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for uneven wear patterns or bulges.
- Measure tire tread depth.
Replace Tires if Necessary:
- Loosen lug nuts with a socket set.
- Jack up the vehicle and remove the wheel.
- Install new tires and torque lug nuts to the manufacturer’s specification (typically 80-100 ft-lbs).

3. Wheel Balancing

Balance Wheels:
- Remove the wheel from the vehicle.
- Use a wheel balancer to check for imbalance.
- Adjust balance by adding weights as needed. Reinstall the wheel.

4. Engine Mount Inspection and Replacement

Inspect Engine Mounts:
- Visually check mounts for cracks or separation.
- Use a pry bar to check for excessive movement.
Replace Engine Mounts if Required:
- Remove the bolts securing the engine mount using a socket set.
- Lift the engine slightly with a jack to relieve pressure.
- Replace the mount with a new one and torque bolts to manufacturer specifications.

5. Drivetrain Inspection

Inspect and Replace Drivetrain Components:
- Check CV joints and axles for damage or wear.
- Replace any damaged components using appropriate tools, following repair manuals for specific torque values.
