Please include the year,make,model,sub-model,engine,2wd,4wd,flex,gas,diesel. Please click accept when done, thank you and come back often. Can you see that the outer cv joint is turning, as seen in this pic, if so then the splines on the hub or halfshaft must be stripped.

i took the hubs apart the splines look fine, put them back and the 4x4 worked fine, put the truck in 2x2 went back to 4x4 and the hubs did not engage, should the hubs stay engaged all the time or what makes them engage and disengage?
Expert:  Mike S. replied 3 years ago.
Do you have a cap on the hub that you can turn to lock and unlock the hubs?
Expert:  Mike S. replied 3 years ago.

On page 170 of your owners manual which I uploaded here http://www.mediafire.com/?j759gafu9hz9k5e

it says the front drivetrain has automatic locking hubs. That is a good question, how they automatically lock up, let me see if I can find a technical answer to that because they may give some clue as to why yours are not locking up.

Customer: replied 3 years ago.
thanks that would be great because like i said sometimes they work and sometimes they dont.
Expert:  Mike S. replied 3 years ago.

I see here it says, "Auto lock hubs engage / disengage via either electric, or vacuum servo." http://www.fordf150.net/forums/viewtopic.php?t=40758

Also, here is someone discussing, "F-150 and have no 4wd. Seems the auto hubs will not lock in." http://www.f150online.com/forums/other-powertrain/223-anyone-problems-auto-locking-hubs-look-here-semi-long.html

"There is a known problem with the auto locking hubs" and "Ford has determined a design defect and has made a replacement part for them."

Expert:  Mike S. replied 3 years ago.

Now I read this, "97 and on F-150's use a totally different setup. No more locking or unlocking at the hubs. Has half-shaft from each front wheel to diff with 2 CV joints in each, like a FWD car. The disconnect is in the diff, on driving the two half-shafts, and has locking dogs. Activation via vacuum line. Transfer case disconnect of front drive shaft is still there. Automatic hub breakage will be a thing of the past."

http://www.f150online.com/forums/other-powertrain/223-anyone-problems-auto-locking-hubs-look-here-semi-long.html

Is there any vacuum lines or anything going to them hubs except the anti-lock brake or speed sensor wires?

Customer: replied 3 years ago.
yes their is im going to check them
Expert:  Mike S. replied 3 years ago.

It appears to me there are vacuum lines, a solenoid

I see alot of posts on those autolocking hubs.

"Go with Warn manual locking hubs. They have had alot of problems with the automatic locking hubs. You only notice that they dont work when you need them. I would get Warn manual locking hubs and be done with it."

http://www.fordf150.net/forums/viewtopic.php?t=7397

 

"I switched over to manual hubs last summer after it started trying to engage by itself. I assumed the hubs were giving out and were locking in on occasion. I went with the warn premium manual locking hubs. I think they were around $85.00."

This is interesting.

"That's a known problem with those hub locks - the fix is to lock them (read your owner's manual or your sun visor) & drive around for ~200 miles to wear-in the front diff. Any time you back up, you have to re-lock the hubs until you put 200 miles on them. The problem is actually in the front diff; not in the hub locks."
