4 wheel drive not working

[mbosmer]

Ok I went out today and my 4 wheel drive was not working. When I put the tansfer case in four low the truck geared down so I think its working fine but could it be my hubs or some thing. Any Help Please.

Auto hubs?

If so, that'd be my first guess if you get gear reduction through the transfercase.

How do you know you didn't have 4wd? Front axle is an open, so only one wheel is going to spin if you have little traction.

Auto Hubs, I pulled up on a hill and got no wheel spin in the front.

my friends did the samething, he replaced his hubs withsome warns and its doing alright now, maybe that will help you.

ckeck your 4x4 fuse under the dash, if that ole boy has a bad fuse in there it aint gonna work, hope you dont get stuck in the woods, I always carry spare fuses

Get some manual locking hubs. That will probably solve your problem, at least that will make you stop wondering if your auto hubs are doing there job.
