It is. Called a Cardan (H-yoke) CV which has 2 u-joints, and a ball joint vs a CV joint which most of the time is a splined ball in a splined hub joint with retainers and a boot covering. It’s recommended to put a cut red spray straw under the boot edge as a breather so the grease has room to expand and not heat the grease and melt out.
Was talking to a fellow Lucky Dog racer last month at Sonoma on Saturday after that days 8 hour race as they were changing out the CV in their car. They could not figure out why they lost the axel. Tore it apart and the grease was gone from the CV. It only had 12 hours on it. Told them to put the straw in the CV boot... My brother builds vintage F1 cars that run CVs to Hewland gear boxes. Every CV boot has a straw...
