Tight transfercase

I pulled the tcase (NP242) as it pops out of all 4WD modes under load and have another to go in. After draining the oil and putting them side by side I did some comparisons. The one I pulled from the Jeep is very stiff to turn even in neutral (oil all drained etc) where as the replacement spins freely and will freewheel when I spin the output shaft. This is the same in all modes of 4WD and 2WD etc.

Which is normal? I'm assuming it should spin easily and the tight one could be due to something being bent in there?? Anyone else have any experience with this?

I would think that a smooth, free spinning shaft would be what you want. It sounds like you have bad/seized up bearings and/or something bent in the other one.

This is just my thoughts, I really don't know much about T-cases, besides what they do.

The T-case should spin with ease in 2 or 4WD.

If it's really stiff, it could be a bad bearing or a bad planetery gear.

Thanks, good to know, or rather confirm what I thought.
