Sick of my 4wd

[Josh99]

So a while back, my 4wd wouldnt work. I changed the auto hubs over to warns and it worked like a champ and everything was all good. The other day me and a buddy were going to ride 4 wheelers and I was waiting on him and I took my truck down a trail to see how wet it was. It wasnt anything crazy at all. I was in 2wd and I slipped down in a low spot. No big deal Ill lock it up and drive right out. Put it in 4hi hit the gas and the *** end sunk down and the fronts didnt spin. I got easily pulled out with a v6 2wd 1500 chevy. Please tell me where to look now. I have been trying driving in reverse and all of that to get it to work and nothing will. When I turn my knob, I dont hear anything happen. Only when I turn it to 4 low you can hear it click and it puts it in low but its still 2wd. Any ideas?

this is a dumb question but did you get out and lock the hubs in?

[Josh99]

Yeah I did

If you don't hear anything when switching to 4hi, i would say your shift motor is either misaligned or dying.

This is what I was thinking. You do have to make sure you lock in your hubs on the front, hence manual locking hubs.

Where is the shift motor? Can I get to it

If it's shifting into low range then it isn't your shift motor. Is the 4x4 light coming on? It sounds like its a broken chain in the transfer case.

leave the switch in 2wd... lock both of the front hubs. then spin the front driveshaft. if it spins, the hubs are engauged and work.


then start working on the T case and wiring. shift motor os on the side of the T case. small black tube.

Ok I just went out left it unlocked and in 2wd and the driveshaft spun along with the u joints on the back of the hub.I locked the hubs and spun the driveshaft, the driverside u joint didn't spin and the passenger side did, with a grinding noise. I'm at work so I can't really do much about it now. What I'm confused by is why these almost new warns are having issues.

Did you have them installed or did you do it yourself?

My suggestion would be over the weekend, rip apart the hubs, and grease EVERYTHING, and then put them back together, and try again.

You said you have push-button 4wd, right? Trace the electrical from the button and look for anyplace the wire might be compromised.

This is why I like lever engaged 4wd.
