Saginaw tranny leaks when on a grade

I recently put some homemade spacers between my leaf spprings center bolt and my spring hangers to position the axle in the center of the fender opening on my 53 chevy pickup. Looks perfect but it left the driveshaft about 2 inches shorter. Now the shaft has about 2 1/2 inches or so showing from the tail of my saginaw 4 speed. And when I left it parked on a grade facing uphill, it left a puddle of tranny fluid. Neve'sr had that problem before. I'm thinking it because of the too short driveline. Didn't mean to create a new problem ,but it appears I did. Am I right in blaming the exposed input shaft on thre tranny?

 

If I read it right, you pulled the drive shaft yoke out too far. Then it wears more and will get slop, then the seal gets worn.

If you hit the right pothole, you may lose the drive shaft and flip the truck.

 

YES, you need to address this problem before you drive it anywhere.

 

Just out checking and there's 2 inches of the yoke shaft exposed. I think the shaft is only 4 or 5 iniches, so obviously it needs a little longer driveline. How much should be showing ? An inch or less?

 

I think that most prefer an inch.

 

IF you are using a older used YOKE ... look closely at the old wear mark ring on the yoke. That is where the real seal should be at ... not where it is currently.



I have found that usually if ... I push the yoke all the way in and pull it back out about 3/4ths of a inch and the wear ring is usually right there. That is where I like to run mine.
