NP246 Failure
Hey guys, i've been hanging around for awhile and finally decided to make an account. anyways, onto the problem.
I've got an 03 chevy silverado 1500 z71 5.3/auto/NP246, and replaced the transfer case back in july with a reman, and just put in a transmission from a wrecked truck about a month ago, after i replaced the transmission i didn't have a shift motor on the transfer case for a little bit and didn't have any issues for awhile but after i replaced the transmission it started coming out of gear into neutral and so i finally got a new motor for it and it was fine for about a week and then it did it again. I thought it just popped out so i tried changing from 2wd to 4wd and back and still nothing happened, wouldn't move. so I ended up towing it home. Well I got the shift motor pulled and tried manually shifting it and it just turned freely so I knew something was up. took the transfer case out and got it tore apart to find quite a bit of metal shavings and chunks of some kind of ring? not sure what it is, scattered throughout it. So I started searching for rebuild kits and found one for cheap and went back to my workbench to look at the T-case again to check what all I would need and realized that my output shaft had snapped! I hadn't realized it before until I looked closer. It snapped in-between the clutch pack and pump. Anyone else had one snap like this? I could't find any post about it. Anyways, What my question is, is, other than the output shaft, what all else should i replace? Will be posting pics in just a moment. Thanks!
