The transfer cases have been swapped, took me 6hrs. Removing the transmission to transfer case bolts was much easier a 13mm ratchet wrench. I replaced the input seal on mine quite a few years back, that was tough with a traditional box wrench. My jack platform needed a few more mods today, but it worked out okay. The transfer cases both stayed in place unless I was trying to move them around. I had a tie down strap front and rear. The front one was just draped over the transfer case input shaft housing and the rear strap was looped over the end of the output shaft housing. There is just barely enough room for the transfer case to slide back and down. I had maybe 1/8" between the input shaft and cross member, the passenger side of the case and the exhaust, the driver side of the case and the fuel tank, the shift motor and connector to the tank as well. Just gotta take your time and keep checking as you lift it back into place.
The USA Standard Gear bearing and seal kit proved for a 2nd time to have an improper seal. The transfer case to transmission seal bolt holes did not line up. I could have fixed that of course, but I had a new Dorman seal and it fit perfectly. In general I think Dorman parts are poor quality, but they have some things that are very good. So the mount seal in the kit was not right and the front output shaft seal did not have the lip on the front to help keep dirt out of the actual sealing surface.
I found with the engine running and in drive, the front output shaft turned, but it was fairly easy to hold it from moving and I could also grab and stop it at will. I only tried this at idle. There was no chance I could hold it still or stop it with the factory installed transfer case. I can now hear the coil engage as well. In drive everything sounds much better now, though the rear bearing for the front output shaft sounds interesting. It doesn't sound bad like the factory installed transfer case, and it may simply be due to sort of like cup it's installed in.
Road test, I only went 8 miles so I'll know more over the next several days. Currently it is smoother and quieter, but seems to still have a very little bit of vibration under power, that cannot be felt at all until the torque converter locks up. Under coast below 55mph I can't feel any vibration. Under coast from 80mph I can't feel it as much, but it's still present in the steering wheel, brake pedal and seat. I can still hear the vibration under coast from higher speeds. I have no reason right now to think it's the transfer case.
Tomorrow I'll see what my scanner thinks of the new parts and test shifting more.
