    So figures on the first decent snow of this season I end up having trouble with my 4X4. I was wondering if anyone could give me a direction to look for the problem.
    -The hubs turn and one moves to the locked position, but the other makes it almost all the way. Only about the width of the arrow on the part that turns away from locked. It may actually be locked but not sure.
    -It seems like the transfer case is shifting because when I try to put it in 4Lo and then shift the truck to drive, back to N and then reverse I hear it click or grind a little like it has always done in 4Lo. This goes away in 4Hi and 2 wheel.
    -Not sure if something is froze, but we did have a crazy mix of rain/sleet and later snow overnight.

    Where do you guys think I should start looking? or what are some tests I should do to narrow it down. The only problem I had last year was the splines in the slip joint of the front drive shaft went bad, but I replaced the shaft with another one I had and everything was fine after that. Thanks in advance for any help.

    I've got an 83 k20 That has warn hubs on it. about 2 years ago, mine got really hard to turn, I had to take a channel lock to turn them to be able to plow. After that storm I replaced them with new & haven't had a problem since. I'm happy with the warn.

    It ended up being the hubs. I replaced them and everything seems fine now.

    On the old chevy's if only one hub is locked in it could cause a grinding noise in the front end from only being partially locked in. your best bet when one fails is to leave them both unlocked. That is of course unless you want to replace both of them instead of the one bad one.
