Transfer box front bearing replacement

[beemer]

On a 95 D1 the front transfer flange now has visible movement of around .015", 20,000 miles ago it was detectable by feel only. Vehicle has 102K miles.
Question, can that bearing be replaced without pulling the transfer box apart. I would rather replace bearing than a destroyed transfer box later.
Does anyone have a bearing and oil seal part number so I can go to a bearing supply and not the stealers?

Thanks, Carl.....=o&o>.....
