Transfer Case Bearings

Also.....the new front output shaft large bearing is sealed (left with snap ring). The OEM one (right side with plastic cage!) isn't. I saw a video where one guy removed the seals so it would get more lubrication. What's your thoughts on that?

Correction, that's the tailshaft bearing. The one with the big snap ring you have to access through the slot in order to remove the back case. The new snap ring doesn't have the bent out "tails".

I can't read all the numbers to check, but appears to be ball vs roller.

They're both ball. The USA bearing has a plastic cage and the Chinese one has a steel cage. I removed the seals and packed them with grease. Couldn't use that closed gap snap ring though.

So now you want to change the lubrication style? Hope you don't contaminate your Tcase fluid and wreck the whole thing.So what grease did you use and is it conpatible with Tcase fluid? If you used lithium based start over for sure. BTW, those cheap seals aren't meant to be submerged in oil,they will leak. They do make bearings you could do that with, but quite expensive.
You may just be overthinking this too much. Use whats proven to work.

Okay, here's the 3 that need pressing. For what local shops have quoted me I can buy an adequate 1 ton Arbor Press from Harbor Freight. And then I can have one on hand for my Harley Twin Cam's Cam Plate! Although I'm still tempted to just start hammering.

There's actually 5 that needed pressing. Got a great deal on a HF 12 Ton Press. Made it super easy and fun!

I did what YouTube's Eddie Current did in his Gear Box videos. Blue Goo and removed the seals. Changing it would be installing that sealed bearing. It had nearly zero grease in it when I removed the seals.
