Solution

1. Preparation

Gather Tools and Parts: Ensure you have a socket set, torque wrench, jack stands, and safety glasses.
Safety Precautions: Disconnect the battery before starting work to prevent electrical shorts.

2. Remove Front Wheel

Loosen lug nuts while the vehicle is on the ground.
Lift the front of the vehicle with a jack and securely place jack stands underneath.
Remove the lug nuts and take off the front wheel to access the suspension components.

3. Inspect and Replace Components

Control Arms and Bushings:
- If damaged, remove the control arm by unbolting it from the frame and the steering knuckle.
- Replace any worn bushings with new ones.
- Reinstall the control arm and torque bolts to manufacturer specifications (usually around 50-70 ft-lbs).
Ball Joints:
- If the ball joints are worn, detach them from the control arm and steering knuckle.
- Install new ball joints and secure them with the proper torque settings (typically 75-85 ft-lbs).

4. Reassemble the Front End

Reattach the front wheel, hand-tighten the lug nuts, and lower the vehicle.
Torque the lug nuts to the manufacturer’s specification (typically 140 ft-lbs).

5. Final Inspection

Reconnect the battery.
Inspect all components again to ensure everything is securely fastened and properly installed.
