I have a 2007 E-350 SMB 4x4 with the Atlas 2sp transfer case. Noticed a bit of side play wobble at the front drive output shaft. Talking to Advance Adapters, they say to drop the drive shaft and check the big yoke nut first. Then move on to replacing the bearing and seal which can be done externally without removing the unit. Anyone here ever perform this procedure?

It turns out I may not have to mess with the bearing, unless it is deemed toast. While rocking the yoke slightly, we noticed that the nut on the output shaft was staying still, and there was no leak at the seal there. So we think the issue is the yoke, which is a welcome relief. Let's see it that's rue when we drop the shaft and remove the yoke.
