The same U-Joints for front and back of drive axle?

[AngryPirate]

Hey there, I have a 1960 GMC 1/2 ton (1000 series) with a Dana 44 10 bolt diff.

I have the drive axle out and the u-joints out of that (both ends).

The U-joints look the same,does anyone know if they are?

I have been looking at parts sites and it seems that they only mention the rear u-joint. Which I believe is a spicer 1310.

Does anyone know if the transmission end of the drive axle takes the same u-joint, since I'm not finding any differentiation on the usual suspects parts sites.

Thanks!

I would try and measure both joints to compare. Pay close attention to cap to cap measurements on each joint as well as cap size and c clip orientation. Mine had conversion joints on both ends of the DS which made finding replacements and agonizing lesson on u joints. I has a T221 transfer case and a Dana 60 rear. The rear joint had both different cap to cap dimensions as well as different cap sizes.

Thats interesting on the Dana 44 rear axle. I never knew that they were used on GM trucks in that era. Always thought that they got the HO52 axle. Maybe a GMC - Chevy thing?

Thanks for the response. I'll try doing a cap measurement on both as well as cap-to-cap.

I do believe the GMC's and Chevy's were different in this regard. I think a lot fo the driveline/drivetrain components are more different than similar.

Thanks Again!

Just an update for others in the future...

For my truck, with the dana 44 diff, this is what I had to order to replace both U-joints and pinion seal.

pinion seal - Dana/Spicer 44895

u-joints (both) - Spicer 5-153X

u-bolt kit - Spicer 2-94-28X

torque for u-bolts that hold the u-joint to the differential yoke: 14-17 Lb. Ft.

I did find an alternate pinion seal from O'Reilly's that would've worked. It was:

National Seal 5778

Thanks for the input!
