Need source of U Joint specifications

WZ JUNK · March 27, 2021, 12:55:30 PM

I am having trouble finding u joint specification. I know it must be on the net somewhere but I must be easily frustrated today.

I am looking for a joint that is two sizes. It has 1 1/8" cup diameter and 3 5/8" long on one side, and 1 1/16" cup diameter and 3 1/4" long on the other side.

I could use some help.

This any help? I only know what a hybrid u joint is because theres one on my GP. A truck shop built the driveshaft.

That was just a top search result via "spicer hybrid u joints".

Thanks, that is what I needed. I think the one for me is 1310/1330. I will verify that later. I am swamped with grandchildren at the moment.

Check a 1310-1350.

The one I listed I buy at Carquest and napa. I don't remember the part number. If I need to dig, I will.

Neapco 1-5349 is the number that crossed over.

Quote from: "kb426"Neapco 1-5349 is the number that crossed over.

I think that is the right size. I have cross referenced it some and I have noted some slightly different decimal measurements but most agree with the fractional measurements. Thanks

Well so far it is the universal joint mystery from hell. 2 days of trips to and from the auto parts store and to the shop that has a method of pressing them in and out. I will start fresh tomorrow. I have had enough for today.

Better day today. I called a tech at Moog and he and I went over the details. He gave me his best guess and it was the right joint to use. Driveshaft is in the car. I need to finalize the pinion angle and then remove the assembly for final welding and painting. I was able to change the rear axle and use the driveshaft from the last rear axle by changing the universal joint. I never thought I would get that lucky to find a mismatch joint that work

What part number?

WZ JUNK · March 31, 2021, 07:33:57 PM

It is a 355 series. Apparently there is a standard 3 digit number that is used to identify u joints. Part of my problem is that this joint is a external clip on one of the pairs and a internal C clip on the other pair. I was measuring the overall length of each pair but you measure the C clip side to the outside of the clip groove and not the overall length. That makes sense now but it was confusing me at first.
