Solution

1. Preparation

Gather tools including a tire pressure gauge, jack, jack stands, and a torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Inspection and Adjustment

Inspect Tires:
- Check for visible damage (bubbles, cuts, or punctures).
- Look for uneven wear patterns that could indicate misalignment or balancing issues.
Check Tire Pressure:
- Use a tire pressure gauge to measure the pressure.
- Inflate or deflate tires as necessary to meet manufacturer specifications.

3. Wheel Balance and Alignment

Balance Wheels:
- Remove each wheel and take it to a tire shop for balancing.
- Ensure weights are correctly applied for proper balance.
Check Alignment:
- Have a professional perform a wheel alignment if uneven wear is detected or if the steering wheel is off-center.

4. Suspension Inspection

Visual Inspection:
- Check for any signs of damage or wear on suspension components, including bushings, struts, and shocks.
Replace Worn Components:
- If any suspension parts are found to be worn or damaged, replace them according to manufacturer specifications.

5. Testing

Once repairs are completed, take the vehicle for a test drive to confirm that the shaking has been resolved.
