Item Details

'Small GM P/S,''78 and Later
3/4"-30 Spline'

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.

Notes

Tech Tip #1: When using more than two universal joints in a system, a support heim must be used.

Tech Tip #2: Increasing a U-Joint's angle of operation beyond 30° dramatically increases the stress on the joint, weakening the whole steering mechanism. If a greater angle is needed, add another u-joint.

Worked great !

August 20, 2014
Had the weld on end welded on the steering column by a certified welder. I cleaned up the splines on the steering sector with a diamond file and it went on the sector without a hitch. Drilled a small dimple in the sector spline and set the lock nut, Perfect ! :-)
Yes, I recommend this product.

These quality steering U-joints are designed to work on 78 and later GM power steering gears and other applications meeting the same criteria. Below is a guideline to verify spline count that may be helpful: 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. Some aftermarket or other manufacturers of the steering gears and racks may use a different cut or taper on the splines and for verification you will need to check with manufacturer for cross over guidelines.
