Manual Locking Hub Q
Hello: I bought my 17 year-old son a 97 f250 with manually locking hubs. We live in WY where often the main road to his high school is clear but the side roads are icy or snow covered. My question is, if he manually locks the hubs, can he shift from 2H to 4H while moving and if yes, are they any speed restrictions? Someone told me even if he has the hubs locked, he has to pull over and put the truck in N or P to shift into 4H or to shift from 4H back to 2H. Could anyone clear this up for me? Thanks so much!

If you have your manual hubs locked you may shift in and out of 4WD at any speed. You should be going in pretty much a straight line and you should NOT be spinning or sliding any tires when you do it. For that reason I always push in the clutch of a manual trans while shifting the transfer case, and I'll at least let off the gas with an auto, if not shifting it into neutral.
I should note that this only applies to shifting between 2WD and 4WD-high. Generally you should come to a complete stop and put the trans in neutral before shifting into 4WD-low. But you don't need (or want) 4WD-low on snowy or ice roads anyway.

welcome to FTE.
as Bob said, let off throttle and shift between 2 wheel and 4 high. you have to be stopped and in neutral to shift from 4 high to 4 low and back from 4 low to 4 high.
and a good rule to follow is to stay below 45 mph while in 4 wheel drive.
while 4 wheel drive gives you more traction is slick stuff, it does nothing for braking. so it is common sense to go slow when road conditions are not perfect.
