How to replace the steering knuckle on 2500 and 3500 on GMC Sierra 3500 Classic?

Steering Knuckle replacement starts with tire and wheel removal on 2500 and 3500 models which might require wheel drive shaft removal. You must first remove the Wheel Bearing and hub assembly before disconnecting the outer Tie Rod End from the knuckle. Begin by supporting the lower Control Arm along with separating the upper Ball Joint from the knuckle until you reach the lower Ball Joint. Before continuing with the knuckle replacement remove all disconnected components from the vehicle. To install the knuckle put it onto the lower Ball Joint before attaching the upper Ball Joint to the knuckle. Follow the Wheel Bearing and hub assembly installation by attaching the wheel drive shaft only if equipped on the vehicle. After removing the lower Control Arm support, you can reattach the tire with the wheel before checking the wheel alignment.
