Driveshaft install. Something odd?
Installing the driveshaft today and came across a couple of things that didn't seem right. Trans is a recent rebuilt M-22, new u joints, new clutch.
I put the rear of the shaft in and the yoke on the rear would turn when I spun the tire to align the u joint. I tried to turn the yoke on the trans and it is super tight. I seem to remember being able to turn them by hand. Yes the trans is in neutral. Well I turned the yoke using a big screw driver to align one side of the yoke. I got that bolted up and then spun the tire to align the other side and the driveshaft didn't move. The tire spun but it seemed like the shaft wasn't bolted up. The shaft didn't turn. Now I aligned the yoke with a screw driver and when I turned the front yoke, with the screwdriver the tires now spun.
Is the trans supposed to be tight. (M-22). Now why didn't the tire spin the front yoke, it seemed like the rear is in neutral.
I drove the car before I did the 4 speed conversion and the rear worked fine and there were no noises.

when the tire didnt spin the front yoke and drive shaft did you notice what the other rear tire was doing, perhaps spinning in the opposite direction?
the transmission should not be tight if it really is in neutral, you checked the sihft levers on the side of the transmission case?

When I turn the p/s tire the d/s spins the opposite way. When I move the driveshaft with a long screwdriver both wheels turn the same way. I checked the shift rods and they appear to be in neutral.
The thing that seems odd is when I spin the rear tire the driveshaft dosen't move.

1. Not really out of gear. Either shift by hand the rods underneath or have someone in the car while you watch the rods.
2. Yoke seal is new and very stiff.
3. Yoke is rusted to the seal from sitting in humid/moist area.
4. Wrong yoke. In too far and rubbing or something.
5. Transmission broken. Did you check that it spun before putting it in?
6. Yoke is hitting frame.
Now if you have a Positraction, which most before 1970 were and all after were, then wheels should turn the same direction unless the driveshaft is locked (park, in gear, etc.).

A few reasons the transmission yoke could be tight:
1. Not really out of gear. Either shift by hand the rods underneath or have someone in the car while you watch the rods.

Took the linkage off. Put the trans in neutral. Driveshaft will turn with the help of a big screwdriver like it did before.. When the driveshaft turns both tires spin the same way. Why don't the tires spin the driveshaft.
