4wd gone again!
I know there are a lot of posts on this site about fourwheel drive problems but none that match my problem. Last summer my 4wd went out on me. I checked the usuall things(vaccum pressure, relays, ect.) and ended up replacing my transfer case shift motor. It fixed the problem temporarily( a couple of months) and know, once again I have no fourwheel drive. I havent had time to do much messing around with it this time but I was wondering if anyone knew what could be messing with the shift motor. I know they get dirty but it hasnt been on there that long. Thanks in advance. Also is there an idiots guide to doing the neccesary maintenance on hubs? Thanks

As far as the hubs I asked the same question in the regular Superduty forum and I was told the bearings on the wheel are sealed and dont require grease. However there are needle bearings that need grease on the hub itself.
I use to have these 4x4 engage problems all the time on the government ford trucks. It usually meant replacing of the hubs. I was also told you have to come to a complete stop to engage the hubs the first time. Then as long as you dont go in reverse they would stay engaged. These are for the auto lock hubs with shifter in cab. There are so many different combos though. Shift on fly switch, manual hubs, auto hubs manual shift, auto hubs electric shift. What ones do you have?

I have the switch on the dash and i can also lock them in manually witch brings me to another Question. Will I get 4wd buy manually locking in the hubs without the switch in cab working or do I have to use both? Thanks in advance and God Bless your son!

I dont know much about the switch controls I alway purchase the trucks with a manual shifter for the reson you are going through. I hope someone else in the forum can hook you up with a fix on that. However if you try to manual engage you hubs then try you switch to eliminate a posible problem with your hubs. Thanks for the comment on my son and good luck with your rig.

If it ends up being the transfer case gear motor again, you might have a short in a wire that got a lucky wiggle when you replaced the last motor.
When you replaced the last motor were there any shavings, burrs or other debris in the adapter's grease?
The reason I ask is if there was/is that part might be the problem. If there wasn't/isn't and there is no bent or binding linkage there could be an internal transfer case problem that is overtaxing the shift motor.
Hope it's ends up being a cheap and easy fix for you,
