The oil on transfer case side is much lower than the oil seal so only splash oil on that side the bearing being lubricated by gearbox oil.
There was a lad awhile back bought a sealed for life bearing for that location and removed the seal from gearbox side to help restrict oil pathway to transfer case side.
 
transfer box side has a oil thrower keeping the oil away from seal and bearing,there isnt on the gear box side as oils needed to lube the bearing
 
As we’re talking transfer boxes, I currently have my engine and gearbox out and separated. I have a lot more wear/backlash on the front output shaft than the rear. Obviously it makes sense to do this now whilst I have it out of the vehicle. Can anyone tell me what the likely culprits are and what’s best to replace whilst I have easy access. Thanks!!
 
how are you checking front output shaft, if it has up/down side to side play then it would need front bearing,it has rotational play by design

I must admit, I only rotated the prop flange, it just seemed an excessive amount of rotation... must be 10 degrees?
