Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Disconnect the 12V battery to prevent electrical issues while working on the suspension.

2. Inspect and Replace Suspension Components

Inspect Control Arms:
- Remove the front wheels using a socket set.
- Check the control arms for cracks or play in the bushings.
Replace Control Arms (if necessary):
- Remove the bolts securing the control arm to the chassis and wheel hub.
- Install the new control arm and torque bolts to manufacturer specifications (typically around 70-90 ft-lbs).
Inspect Strut Mounts:
- With the wheels off, check the strut mounts for any visible damage or play.
Replace Strut Mounts (if necessary):
- Remove the strut assembly from the vehicle.
- Replace the strut mounts and reassemble, ensuring all fasteners are torqued properly.

3. Check and Replace Sway Bar Links and Bushings

Inspect Sway Bar Links:
- Check for wear or excessive play in the sway bar links.
Replace Sway Bar Links (if necessary):
- Remove the sway bar link from both the sway bar and the control arm.
- Install new sway bar links and torque to specifications (usually around 30-40 ft-lbs).

4. Reassemble and Test

Reinstall wheels and torque to specification (typically 100-110 ft-lbs).
Reconnect the 12V battery.
Lower the vehicle and perform a test drive to confirm the issue is resolved.
