4x4 not working right
i have a 99 f250 sd v10 that when i turn the switch to 4 wheel drive it will work but pops
and makes bad noises when driving in 4wd why is that i noticed when i climbed under the
truck and go to turn the half shafts going into the transfer case one up will turn but the
other will not does this mean that my hubs are bad its auto locking hubs
