2252-683 – Weld Yokes – CVJ Series – Butt Dia 2.344″ – Tube Dia Wall 2.500X0.083

Q: What is the 2252-683 used for?
A: The 2252-683 is a CVJ-series weld yoke designed for independent rear suspension (IRS) driveshaft assemblies. At 3.500" centerline-to-weld, it positions the weld point significantly further from the U-joint than standard CVJ weld yokes -- this is required by the IRS CV socket body depth, which is longer than the conventional front-shaft CV socket.

Q: Do I need the CV ball kit with this yoke?
A: Yes -- the note on this part explicitly states: add CV ball kit, part number 2252-681C. The weld yoke alone does not function as a CV joint; the ball, socket, and spring assembly are required to create the constant-velocity action. Order both parts simultaneously.

Q: Why is the CL-to-weld distance 3.500" on an IRS yoke but only 1.250"--1.750" on front-shaft CVJ yokes?
A: IRS CV joints in independent suspension systems must accommodate larger suspension travel angles and use a deeper CV socket design to maintain centering across the full articulation range. The deeper socket requires the weld joint to be positioned further back on the tube to maintain the correct effective tube length and CV socket engagement depth. Using a shorter CL-to-weld front-shaft yoke with an IRS CV kit will result in the socket bottoming against the yoke before full compression travel is reached, causing binding.
