Another D20 Front Output Shaft question

When I removed the transfer case to reseal the transmission, I noticed the front output shaft yoke had a lot of end play on the shaft. After resealing the transfer case when I went to torque the nut on the front output shaft the mud slinger on the yoke binds up solid on the case.

Is there supposed to be any shims / spacer between the yoke and front output shaft bearing?

I've looked all over this site and google and I don't see any reference to shims or a spacer on the front yoke. Anybody have any clues?:mad2:
 
So you had the front flange nut removed, right? There is a washer that is supposed to go between the nut and the flange. Is that in place? Did you go any further than removing the flange to get at the front seal? If you search the nets for exploded views of the d20, you should be able to find several that have all the parts called out. There is a spacer shim retained by a snap ring on the front shaft, but iirc, the front bearing must be removed to access them. So if you didn't go that for, those should still be in place.
 
Hey trever, I did not go any further than replacing the seal on the front output shaft. There is an o ring under the washer then the nut but it seems there should be a spacer between the yoke and the front bearing. I believe the po at some point in the past backed of the yoke nut so it wouldn't bind but then the yoke slides back and forth about 1/16" 1/8" an I know that ain't right. Danny
 
Nope it ain't. That nut should have at minimum a hunert and fitty footy powndz uh torks on it. Damn tight in other words. You've got something funky going on there. I have a feeling that there's more to this than the shim spacers on the shaft end plate.
 
I removed the end plate and the yoke was still bound up. I've looked at several exploded views and did not see any shim / spacer between yoke and bearing. Will the front yoke cover come off of the shift rails without removing them?
 
I can't remember. The spacer shim and snap ring is between the front bearing and a drive gear, not between the flange and the bearing.
