Application

When purchasing U-Joints, 3 easy steps will help ensure that they will be correct for your application.

STEP 1
Be sure to measure the diameter of the shaft and count the number of splines on the shaft. Some shafts have a blank spot ground on one side. To get the correct number of splines, use a flat edge and cover the blank half of the shaft through the diameter and count the splines on the other half. Multiply that number by 2, thus giving you the total number of splines on the full circumference of the shaft.

STEP 2

Choose which shaft type best suits your application: 3/4" weld on, 3/4" DD or 1" DD.

STEP 3
With these two pieces of information at hand, refer to our chart to find the appropriate part number of the ujoint for your specific application.

Instead of welding the joint on the steering shaft, I drilled and tapped two 5/16 holes in the joint, drilled divits on the shaft which align with the set screws. Safe and easy the disassemble if needed.

Used it to adapt my steering column to a crown Vic steering rack yoke, and it worked perfectly for my application. I was a little worried to buy it at first because I've read about differences between the dodge and gm applications, but overall it worked great. I'll be recommending this to folks on my C-Body forum.
