Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, suspension strut tool, and wheel chocks.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the suspension components.

3. Inspect and Replace Shocks/Struts

Inspection: Check for oil leaks, dents, or physical damage on the shocks/struts. If they are damaged, proceed to replace.
Removal:
1. Disconnect any electrical connectors from the shocks/struts.
2. Remove the lower mounting bolts using a socket set.
3. Remove the upper mounting nuts from the strut tower.
Installation:
1. Install the new shocks/struts in reverse order of removal.
2. Tighten upper nuts to manufacturer specifications (consult repair manual for torque values).
3. Reinstall lower mounting bolts and torque to specifications.

4. Check Springs

Inspect the coil springs for cracks or deformation.
If damaged, replace the springs by removing them from the struts during shock replacement.

5. Alignment

After replacing suspension components, take the vehicle to a professional alignment shop to ensure proper alignment settings.
