Would you recommend using these sealed bearings over the open ones and why or why not.

Willys Jeep Parts Tech:
Sealed bearings are a good idea to keep fluids in each separated

If you replace original bearing with new sealed bearing, do you need to still install felt/neoprene oil seals?

Willys Jeep Parts Tech:
No you cant use both. One replaces the other.

I'm trying to fix a leaking problem. Can I replace the input and output sealed bearing from the outside without dismantling the transmission?

Willys Jeep Parts Tech:
Sorry, youll have to take apart.
