front axles not engaging in 4 wheel drive
Took the Bronco out this weekend and could not get the front axle to engage. The manual hubs were locked and the front drive shaft spins but no movement on the front axle going forward. When shifted into reverse the 4 wheel drive worked.
Before I start ripping things apart I was wondering if anyone had any suggestions or thoughts about what could cause this.

I'm not sure of your symptoms. Are you saying that you can spin the front driveshaft and the front axles and U-joints dont spin? Or are you sayiny that just your wheels dont spin? Easzy way to check this (with the truck off) shift tranfercase to 2WD and hubs unlocked, reanch under and turn the driveshaft by hand. You can see the u-joints by the wheels turn. Lock the wheels and try again. If the driveshaft doesnt turn, than its probubly in the tranfercase.

That is what I am trying to figure out. If I engage the hubs and spin the wheels both wheels turn so I'm not sure if the diff is broken or what.
there is obviously a disconnect somewhere so I guess I will just start taking it all apart and hope that a broken part falls out

I was expecting the axles to turn when I had the xfer case engaged.

Paul why do you say that his transfer case is busted too? Not sure I see where you're getting that from.
