Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, tire pressure gauge, wheel alignment tool, and torque wrench.
Ensure the vehicle is on a flat, stable surface and the engine is off.

2. Tire Inspection and Balancing

Remove the wheels using a lug wrench.
Inspect each tire for uneven wear, bulges, or damage.
Check tire pressure and inflate to the manufacturer's recommended PSI.
If tires are unbalanced, take them to a tire shop for rebalancing.

3. Suspension Component Inspection

Visually inspect control arms, tie rods, and bushings for signs of wear or damage.
Push down on each corner of the vehicle to check for excessive bounce or play.
Replace any worn or damaged components as necessary.

4. Wheel Alignment Adjustment

Use a wheel alignment machine to check the alignment settings.
Adjust camber, toe, and caster settings according to manufacturer specifications.
Tighten all adjustment bolts to the specified torque values.

5. Test Drive

Reinstall the wheels and torque lug nuts to the specified value.
Lower the vehicle and take it for a test drive at various speeds.
Observe if the shaking persists and whether any new symptoms arise.
