Item Details

Vega, Corvair, GM Rack
5/8"-36 Spline
O.D. is 1-1/8" and total length is 3-3/4".

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.

steering u joint

August 10, 2014
Bought a t bucket from a guy who obviously put it together with no money at all. Speedway talked me through several issues I had, one of them being the steering u joint. I bought the wrong one initially, but called them and sent the other one back, they crossed in the mail, but I got my money back as soon as they received it. Car steers 100% better now.
Yes, I recommend this product.

great product for the price

December 26, 2010
the fit is a little tight on the 5/8 end but I'm using it on a metric box so that probably explains the fit. I was able to make it work OK with a little massaging.
Yes, I recommend this product.

The two wheel drive S10 boxes will have either 3/4" - 30 spine or 13/16" - 36 spline input shaft. U joints 91032293 or 91032296 would be the two options depending upon the input spline of your box.

Yes this U-joint will fit a Vega steering box. Yours from Flaming River will still accept this 5/8" - 36 spline U joint.

How is this held on each end? Does this have a pinch bolt on the spline end and a set screw on the double D end? Or are they weld on?
