    Default Anyone know about driveshafts?

    I know this may not be the right place to start but i figured a bunch of car guys might be able to help me out here. I replaced my transfer case encoder motor on my 2004 suburban 2500. While i had the front driveshaft off, i ended up needing to put the transmission from park into neutral so i could reposition the transfer case to neutral manually from underneath the truck to install the new part. Me being forgetful, i reinstalled everything, lined the driveshaft back up to the marks i made and then got back in the truck and shifted back to park... the question i have is did i just fuck up by doing that? Obviously the shifting linkage is tied into the transfer case or else i would have been able to freely turn the transfer to neutral by hand while the truck was in park. So now im thinking i fucked up and my driveshaft is not properly reinstalled. I also rotated the shaft by hand a bit while i was under it so i have no idea how to get everything lined back up. Any ideas on this or did is it not something i need to worry about?

    I would take it apart, reinstall, drive it and test 4wd. If it works and doesn't make any noises or vibrations, awesome.

    Ill give that a go. Im assuming since i already screwd up alignment last time, theres no real point in marking the shaft again except maybe the yoke up at the trans.

    Well something is screwed. Started the truck, runs fine, put it in gear, wont move. Shift to park and get a terrible buzzing or high speed grinding from the transfer case area. If i go back to any other other gear it stops and the motor runs fine but there is a little bit of a whirring noise in reverse. But like i said, no connection to the wheels at all. Something is either broke or way off in the transfer case i guess. Still have the service 4x4 message and red neutral light on dash switch.
