So an update to yesterdays troubles.
was pulling away from a light normal and something clunks. Does not seem to shift right after that for a mile or two and then nothing. I put it in park and hear grinding for a few seconds. Take my foot off the brake and truck and trailer begins to roll (so park does not hold anymore) I have nothing in any gear and nothing in 4 high or low. I can hear grinding while its in drive and bad grinding when switched back to park and noise sounds like it is coming from transfer case.
So after I have it towed 75 miles and I get back I drain the fluid out of the transfer case expecting to see some broken things come out with it, but I did not notice anything. I have not strained the fluid yet though.
Question is what can (and maybe is likely) to be wrong inside of there, and where is a good place to order a rebuild kit??

Thanks
Joe
