4x4 Not Working....Help

[CAT797]

Hey guys, need some help....

My 4x4 is not working. I have the manual shift/manual hubs. I checked today and when I put the t-case in 4x4, the front driveshaft is turning, so I think I'm good there. When I put the hubs in lock, I can't get the front end to bind up on dry pavement, in 4x4 or 4x2. I think that I have some bad hubs........can anyone confirm? I believe this is a known problem/weak spot.

So if I'm right, what to buy? how much will this cost me?

Also, when I got stuck the other night w/o 4x4, I noticed that I only had the one-wheel-peel, so my Limited slip doesn't seem to be working good either. Should I drain the fluid and replace? With what?

Thanks for the assist.......

the known issue is usually for the auto lock hubs... take them apart and inspect them for wear.... i have never really heard of the manual hubs breaking....

as far as your rear LS.. the OEM LS are not that good to begin with.... your truck is pretty new for it to stop working already.....

if you really think about it we dont really have a full 4wd trucks... without full lockers we will always have 1 wheel peel....

my suggestion is pull out the rear LS for a detroit locker... and put a selectable locker on the front..... only if you really use your 4x4 that often.... you will def feel a diff with going with full lockers....

Right front manual hub is junk. Pulled it out and found all of the needle bearings from the assembly floating freely. Guess I need to buy some new hubs. The other side looked fine though.
