Solution

1. Preparation

Gather tools and parts: Ensure you have all necessary tools and replacement parts ready before starting the repair.
Safety precautions: Park the vehicle on a level surface, engage the parking brake, and put on safety gloves.

2. Inspect and Replace Suspension Components

Remove Wheel:
- Use a lug wrench to loosen and remove the wheel securing nuts.
- Remove the wheel and set it aside.
Inspect and Replace Damaged Struts/Shocks:
- Locate the struts/shocks and verify their condition.
- Disconnect any electrical connectors if equipped with electronic dampening.
- Unbolt the strut/shock from the top and bottom mounting points using a socket set.
- Remove the strut/shock and replace it with a new unit, ensuring alignment with mounting points.
- Torque the bolts to manufacturer specifications (typically around 40-60 lb-ft).
Check and Replace Bushings:
- Inspect control arm bushings and sway bar bushings for wear.
- Remove any damaged bushings using a bushing removal tool.
- Install new bushings and ensure they are properly seated.
Replace Sway Bar Links if Necessary:
- Locate the sway bar links and inspect them for wear.
- Unbolt the sway bar link from both ends using a wrench.
- Install the new sway bar link and torque bolts to specification.

3. Reassemble and Lower Vehicle

Reattach the wheel, hand-tighten the lug nuts, then lower the vehicle.
Torque the lug nuts to the manufacturer's specifications (typically 80-100 lb-ft).
