I have a 1987 f150 4 speed. Recently I was driving down the road with my hubs locked (in 2wd) and i heard a clicking. I pulled over, unlocked the hubs and went on my way and didn't hear the clicking anymore. Then a couple days ago I had to put my truck in 4X4 and the front wheels were not spinning and all I heard was a really bad clicking noise (way worse than the one driving down the road). If anyone has ideas of what this may be, I'd love to hear them.

every thing here says broke axle if its in 2wd with the hubs unlocked it wont turn
Universal Joints may be going bad in it as well. I had a similar problem with a clicking noise from my drive shaft and it turned out to be the rear U-joint was going bad. I would look into those as well, since they do not spin when the hubs are unlocked.
Jack the rear end up and put it on jack stands, lock your hubs in, shift it into 4 wheel drive and put it in gear and have someone look from the side (so as not to get run over)to see which axle is turning up front while you are on the ready for the brake in case it would take hold. If the front drive shaft is spinning then one of the front axles should be as well unless your problem in in the diff itself. I had a pinion break behind the bearing once that prevented the axles from spinning. You have an open differential up front and the axle with the least resistance will be the one turning and it will also be the one with the problem. The passenger side uses a two piece axle that could be stripped if not that and the axle isn't broken its a stripped hub or incorrectly installed hub.
