Transfer case planetary gear noise

Ok so I was installing my SYE and I got the transfer case completely apart. While looking it over and cleaning out the internal components I spun the planetary gear and it spins ok but it seems to make a slight grinding noise and has a slight catch as it spins around. Since I have never taken these things apart I am not sure if this is normal gear noise, the gears appear ok from the outside but I haven't taken apart the input bearing and planetary gear assembly. Any ideas? Thanks

Either run it or replace it.

It is a 20 year old piece of equipment.

Replace everything you are working on or just replace what breaks.

It is the never ending story. Replace before it causes further damage but how far is too far and how much money do you want to spend.

I can't figure it out myself. I like doing things right but I don't want to be that guy that has $40,000 in a Jeep that sells for $6,000.

Good luck my friend!
I would rather have a broke Jeep, than no Jeep at all.
