The 1947 - Present Chevrolet & GMC Truck Message Board Network - View Single Post - So, that's why it was leaking so much today!

I know this has been posted before, but here is a link to an exploded diagram and maintenance/rebuild info on the Rockwell T221.

I'm still investigating what all is involved with replacing that bearing on the back side of the input shaft.

Am I correct in assuming this is a repair that needs to be done with the transfer case removed from the vehicle?

Also, here is a great thread I'm reviewing concerning issues with swapping an NP205 in place of the Rockwell.

I know two boardmembers who are going to be getting some questions for me - 1969 GMC and Jakes 68GMC
