Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Using a hydraulic jack, lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Suspension Components

Inspect Components:
- Look for cracks, wear, or damage on struts, shocks, and control arms.
- Check bushings for cracks and ensure they are not deteriorated.
Replace Damaged Parts:
- If struts or shocks are found defective, remove the old components using a socket set.
- Install new shocks or struts, ensuring they are torqued to manufacturer specifications (usually around 40-80 ft-lbs depending on the part).
Replace Bushings:
- If bushings are damaged, remove the affected suspension arm and press out the old bushings using a bushing tool.
- Install the new bushings and reassemble the suspension components.

4. Reassemble and Lower the Vehicle

Reattach any components that were removed during inspection and replacements.
Lower the vehicle back to the ground and remove jack stands.

5. Final Checks

Tighten all nuts and bolts to their specified torque values.
Ensure no tools or debris are left under the vehicle.
