Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely supported by jack stands.

2. Remove Wheel

Loosen the lug nuts using a socket wrench.
Raise the vehicle with a jack and remove the lug nuts completely.
Take off the wheel to access the ball joint.

3. Inspect Ball Joint

Check the ball joint boot for tears or damage.
Use a pry bar to apply leverage; if the ball joint moves excessively, it needs replacement.

4. Replace Ball Joint (if worn)

Disconnect the steering linkage: Remove the cotter pin and nut from the ball joint using a wrench.
Remove the ball joint: Utilize a ball joint separator tool to detach the ball joint from the control arm.
Install the new ball joint: Position the new ball joint into the control arm and secure it with the nut. Torque the nut to the manufacturer's specifications (typically around 37-50 ft-lbs, but confirm in the service manual).
Reconnect the steering linkage: Insert the cotter pin and tighten the nut.

5. Reassemble

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specifications (usually around 140 ft-lbs for the GMC Sierra).
