Solution

1. Preparation

Gather tools: socket set, wrench set, jack stands, and torque wrench.
Park the vehicle on a flat, stable surface and engage the parking brake.

2. Inspect and Replace Suspension Components

Inspect Shocks/Struts:
- Remove the wheel to access the shock/strut assembly.
- Check for oil leakage or physical damage.
Replace Damaged Shocks/Struts:
- Use a socket set to remove the bolts securing the shock/strut to the vehicle.
- Install new shocks/struts, ensuring they are torqued to manufacturer's specifications (typically 30-50 ft-lbs depending on the model).

3. Check and Replace Bushings

Inspect all suspension bushings for wear or cracking.
Use a wrench to remove any bolts securing the control arms.
Replace worn bushings with new ones, applying grease as needed.

4. Alignment and Tire Balancing

After replacing any components, have a professional alignment performed to ensure the vehicle is properly aligned.
Balance the tires if uneven wear is noted.

5. Test Drive

After repairs, take the vehicle for a test drive over bumps to confirm that the shaking has been resolved.
