Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and is secure with wheel chocks.
Safety goggles and gloves should be worn.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle, then secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Components

Shock Absorbers/Struts:
- Remove the lower bolts securing the shock absorber/strut to the knuckle using a socket set.
- Remove the upper mounting nuts from the top of the strut tower.
- Replace with new shock absorbers/struts, ensuring they are correctly oriented.
- Torque lower bolts to manufacturer specifications (typically around 30-40 ft-lbs).
Suspension Bushings:
- Inspect control arm bushings for wear or cracking.
- If damaged, remove the control arm by unbolting it from the frame and knuckle.
- Replace worn bushings using a bushing tool or press.
- Reinstall the control arm and torque bolts to specifications.

4. Reassemble and Lower Vehicle

Reinstall any removed components in reverse order.
Double-check that all bolts are torqued to specifications.
Lower the vehicle back to the ground.
