• Corrosion or stripped hardware at the yoke connection

Installation Notes and Tips

Verify the bearing cap diameter and bolt hole center-to-center spacing before installation. Confirm whether the vehicle uses a front shaft or rear shaft application, since fitment varies by model and drivetrain position. Clean the yoke mounting surfaces before tightening the strap and bolts to the manufacturer’s specified torque. For fitment examples, this part fits 2015-2020 Chevrolet Silverado 1500, front shaft all joints; fits 1999-2014 Chevrolet Tahoe, rear shaft all joints; and fits 2002-2008 Cadillac Escalade, rear shaft all joints.
