Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire and Wheel Inspection

Tools Required: Tire pressure gauge, jack and jack stands, torque wrench.
Sub-steps:
1. Check tire pressure and inflate to the recommended PSI.
2. Inspect tread depth and look for any signs of uneven wear or damage.
3. If imbalance is suspected, remove the wheel and have it balanced at a tire shop.

3. Suspension Components Check

Tools Required: Socket set, pry bar, torque wrench.
Sub-steps:
1. Visually inspect suspension components for cracks or excessive wear.
2. Use a pry bar to test for play in bushings and ball joints.
3. Replace any damaged parts according to manufacturer specifications.

4. Drivetrain Inspection

Tools Required: Socket set, torque wrench, pry bar.
Sub-steps:
1. Inspect the driveshaft for any signs of wear or damage.
2. Check CV joints for tears or leaks, and replace if necessary.
3. Tighten any loose bolts to the manufacturer's torque specifications.

5. Engine and Transmission Mounts

Tools Required: Socket set, pry bar.
Sub-steps:
1. Inspect mounts for cracks, tears, or separation.
2. Replace any failed mounts with OEM parts, ensuring proper torque during installation.
