Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, OBD-II scanner, tire pressure gauge, wrench set.
Raise the vehicle using a jack and securely support it with jack stands.
Remove the front and rear tires if necessary for inspection.

2. Inspect Tires

Check for uneven wear patterns or visible damage such as bulges or punctures.
Measure tire pressure with a gauge and adjust to manufacturer specifications if needed.
Torque: Ensure lug nuts are tightened to the manufacturer’s specified torque after mounting.

3. Check Wheel Alignment and Balance

Use an alignment tool to check the alignment settings. If out of specification, adjust accordingly.
Balance the wheels using a wheel balancer if vibrations persist after tire inspection.

4. Examine Driveshaft

Inspect the driveshaft for any signs of bending, cracks, or misalignment.
Replace any damaged components and ensure proper installation.

5. Inspect Engine and Transmission Mounts

Visually inspect mounts for cracks, separation, or deterioration.
Replace any failed mounts to prevent engine movement that could cause shaking during acceleration.

6. Test CV Joints and Axles

Check CV joints for torn boots or play by manually rotating them.
Replace any worn or damaged axles or joints.
