What is it? GM lists this f joint under number 19461922. It is catalogued under Shafts & Drivetrain > Joints & Couplings.
Anything to check first? A vibration that appears only in a narrow speed band points at balance or phasing rather than at wear. Confirm the number before you order, because a near match will bolt on and still be wrong. Send the VIN if the old marking has gone.
What else matters? Corrosion at a mounting face is worth cleaning back before fitting anything new, because a part that sits on scale will work loose.
