I removed my drift shaft to get balanced since I have felt a vibration at 55-60 mph.
After removing the driveshaft I noticed there is some play in the output shaft when I grab ahold of the yoke on the transmission.
The play is a slightly up and down. If my memory serves me right that should not be.
Seal is not leaking but was curious if anyone has diagram of this yoke off the output shaft.
I know in past on other vehicles there is sometimes a crush washer.
Also what is the torque specification for that output shaft nut?

 

Those yokes can wear. I do not know the tolerances but new ones are not that expensive.

I would just R&R it with a new one.

 

Are you talking about a 2wd?

 

Mine has a little play in it also... has had it for the last 75K miles when I last checked it. No vibration problems as of yet. By the way, I had driveline vibration at that point also (that's why I checked it). I had a custom driveshaft built for me from a company in Texas that makes racing driveshafts. Vibration went away with that new shaft and it was smooth as glass, so I'm sure the play in the output wasn't causing any vibrations.
