Drive shaft, u-joint, yoke questions: 1928 Dictator

[deburt65]

Finally got my drive shaft off my 1928 Dictator, and found the front u-joint was "toast", and has damaged the yoke. Can anyone tell me if the yoke can be repaired, as the u-joint has opened the holding holes in the yoke. A new u-joint will not be held tightly in place at this point. A new yoke would be the answer, but finding one will probably be an issue. Any suggestions would be deeply appreciated. Any drive train specialist out there???? And does anyone know if the yoke screws onto the drive shaft, or driven on....???? Thanks for any information you may share.

Hi, deburt65. I posted a response to your post on the Studebaker Drivers Club website. By what you say here I'm assuming that the part of the ujoint that is damaged is the rear part of the joint actually attached to the driveshaft. As I said in my SDC post, the front ujoint can be removed from the driveshaft simply by unscrewing the packing nut at the rear end of the ujoint. You only need a pair of pliers. Once that is done, the joint will slide off the driveshaft. Please note the locating arrows on the joint and the driveshaft. As far as locating the part, I would certainly advertise for one. You never know. Someone will have one. Failing that, there must be a driveline specialist somewhere near you that you could take it for possible rebuilding.

Thanks Terry for your reply. Not sure what packing nut you are referring to.....my yoke seems to be pressed on or screwed on the drive-shaft. I am planning to take the whole thing to a machine shop that I am told can fix anything.

I have a '30 drive shaft with enclosed CV joint and slip yoke. Flange mount on both ends. I can get a picture and measure if you think it will help. It is from a low mile car in good condition. I changed the transmission and made a modern drive shaft.

The front ujoint is also referred to as a slip yoke because it is splined to the driveshaft and is free to move fore and aft on the shaft. The packing "nut" does not look like a nut. It is more like a screw on cap on the rear end of the slip yoke and needs only a pair of pliers to unscrew it. Once that is unscrewed and pushed back on the shaft, the yoke will slide off the splines.

Thank you Terry........I finally understand what you are telling me. I have everything loose, from trying to get to the u-joint, but haven't tried to push off the yoke. It may be rusted on, so some penetrating oil may be needed. I will try to 'tap" it loose, but with tender care. Thanks, you were of great help. You may have also seen that "Stude30" has what sounds like the same drive-shaft from a 1930 model that may be an easy solution. We are checking it out.

The drive shaft has a total length of 51" long with slip yoke all the way in as pictured.

It's amazing how much resistance a thin film of grease will offer in cases like this. A good rap with a hammer is probably all that's needed to remove it.
