Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during repair.

2. Raise the Vehicle

Use a floor jack to lift the front or rear of the vehicle, placing jack stands under the chassis for safety.
Ensure the vehicle is stable and secure before proceeding.

3. Inspect and Replace Worn Components

Shocks/Struts:
- Remove the wheel using a socket set.
- Unbolt the shock/strut assembly from the top mount and lower control arm.
- Compare the old shock with a new unit for compatibility.
- Install the new shock and torque to manufacturer specifications (usually around 30-40 ft-lbs).
Sway Bar Links:
- Remove the sway bar link by unbolting the top and bottom fasteners.
- Compare the old link with the new one for length and fit.
- Install the new sway bar link and torque to specifications (typically 20-30 ft-lbs).
Bushings:
- Remove control arms if bushings are worn.
- Press out old bushings using a bushing removal tool.
- Press in new bushings and reinstall the control arms, torquing to specifications (varies by vehicle part).

4. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands, then fully torque the lug nuts to the manufacturer’s specification (usually around 100-110 ft-lbs).
