Front End Problem

Im having a problem going forward in my 1990 fullsize bronco. It goes in reverse just fine but when i put it in drive my front wheels lock up and my rear wheels just spin. So i thought ok my maybe its my transfer case since i just got done rebuilding it. i disconnected my front drive shaft and it still didnt go any where. so i knew it wasnt my transfer case. Im thinking its my front axle. i ask several people and nobody can figure it out. so i figured i would ask u guys before i started tareing into my front axle. If anybody knows what the problem might be please tell me i would really appreciate it.

P.S this happen after i got done pulling my car.

I would put it on jack stands and check if the front brakes are sticking or the axle is locking up. Next I would check if you have locking hubs or the mechanism for the hubs is releasing. Check front bearings go through the system slowly.

I checked my brakes,wheel bearings,and my locking hubs and everything was fine. Im guessing its my front axle.

Pull the cover and look you have to do this to pull an axle. I would suspect a damaged gear.
