97 Ram transfer case help

I was kinda wondering if it could be the pinion bearing too. looking at it, it is leaking pretty badly out the pinion seal. I was going to change the seal, but I guess it won't be much more to pull axles and check the bearing. I did check the front shaft u-joints when it was in park, and spun the front shaft and nothing felt like it was binding. The u-joints are probabally the originals; front and rears.
