Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent rolling.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Shock Absorbers/Struts

Tools Required: Socket set, torque wrench, strut spring compressor (if replacing struts)
Remove the wheel to access the suspension components.
Detach the bolts securing the shock absorber or strut to the lower control arm and upper mount.
If replacing struts, use the strut spring compressor to safely remove the spring from the old strut and install it onto the new strut.
Install the new or refurbished shock absorber/strut in reverse order, ensuring all bolts are torqued to manufacturer specifications.

4. Replace Sway Bar Links and Bushings (if applicable)

Remove the old sway bar links by unbolting them from the sway bar and suspension.
Install the new sway bar links and bushings, ensuring they are tightly secured.

5. Lower the Vehicle

Carefully remove jack stands and lower the vehicle using the hydraulic jack.
Replace the wheels and torque lug nuts to specifications.
