Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace Worn Components

Remove the Wheel
- Use a lug wrench to loosen and remove the wheel bolts.
- Take off the wheel and set it aside.
Inspect and Replace Shock Absorbers/Struts
- Locate the upper and lower mounting points of the shocks/struts.
- Use a socket set to remove the bolts securing the top and bottom of the shock/strut assembly.
- Carefully detach the assembly from the vehicle.
- Inspect the new shock/strut for any defects before installation.
- Install the new shock/strut by reversing the removal process, ensuring the bolts are tightened to the manufacturer’s specified torque settings (typically around 50-70 ft-lbs).
Replace Sway Bar Links
- Locate the sway bar link connected to the strut and sway bar.
- Remove the bolts securing the sway bar link using the appropriate socket.
- Install the new sway bar link, ensuring it is properly aligned and secured.
Check and Replace Bushings
- Inspect the control arm and sway bar bushings for wear.
- If damaged, use a bushing removal tool to replace them with new bushings, following the manufacturer's instructions for installation.

3. Reassemble

Reinstall the wheel and securely tighten the lug nuts in a crisscross pattern to the manufacturer's specifications.
Reconnect the battery.
