Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, wrenches, torque wrench, pry bar, and safety goggles.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which suspension component needs inspection or replacement.
Secure the vehicle with jack stands to ensure stability.

3. Inspect and Remove Damaged Components

Carefully inspect the struts/shock absorbers, control arms, and bushings for any visible damage.
If damaged, remove the strut or shock absorber by:
- Disconnecting the upper mounting bolts using the socket set.
- Removing the lower mounting bolts.
- Carefully pulling the strut/shock absorber out from its mount.

4. Replace Components

Install new struts or shock absorbers:
- Position the new strut/shock absorber in place.
- Secure the lower mounting bolt and upper mounting bolts, tightening them to manufacturer specifications (typically around 30-40 ft-lbs for lower bolts, but refer to the service manual for precise torque values).
Replace any worn control arms or bushings by removing them and installing new ones, ensuring they are torqued to specifications.

5. Reassemble and Lower the Vehicle

Reattach any components that were disconnected during removal.
Lower the vehicle back to the ground and remove the jack stands.

6. Final Inspection

Inspect all bolts and connections to ensure everything is secure.
Perform a final check on the alignment and tire pressure before test driving.
