Hi everyone
I have a f350 08 diesel 6.4l for two months so far
I want to know how to shift from 2 wheel drive to 4x4
if there is a video or a step by step explination would make it so easy
I apriciate your help in advance
thank u

 

Two 4x4 systems out there...basically same operations. The manual is very clear on this but if you didn't get any manuals you can get them from ford.com under owners.

Shift on the fly...drive the truck and as you are moving with the **** you can change into 4HI..I think up to 55 mph.

to use 4 lo...come to a stop, trans in "N" then switch **** into 4lo.

Do the reverse when taking it out of 4lo. Trans must be in "N" before switching to 4 hi or straight to 2Hi.

Manual systems are the same with the exception that you must get out and lock your hubs in manually.

BTW even with the shift on the fly you can if needed get out and manually lock your hubs in. Designed that way incase you are stuck and cannot get moving to make the shift on the fly switch.

 

assuming everything is good with your truck, it should be as simple as turning the switch on the dash... Your owners manual would be great with the specifics.

when I bought mine used the owners manual was missingthow

even thow you have the 6.4 diesel you can also post in the 1999+ super and heavy duty forum for a quicker responce. For motor specific questions, I would come here to post.

thank u for the explination
how do i lock your hubs in right or left

 

should be marked auto and lock.

Not sure of the direction unless I went out and looked...should be marked on the hubs.

 

Counter Clockwise is Auto. Clockwise is Locked.

 

One thing to keep in mind, if you're off road and get stuck, then try to go into 4 wheel, your hubs will not auto lock without a full rotation of the front tires. So manual lock is necessary at that time.

 

I thought it was 35, Scot. Oh no! Now we'll have to do homework!

 

Read the manual I guess. I have switch as high as 55.

 

I have too, but it's scary.

 

Electronic Shift On the Fly (ESOF) 4x4 system (if equipped)
If equipped with the electronic shift 4WD System, and the instrument panel control is moved to 4X4 LOW while the vehicle is moving above 5 mph (8 km/h), the system will not engage and no damage will occur to the 4WD system. Before 4X4 LOW can be engaged, the vehicle speed must be below 5 mph (8 km/h) with the transmission in N (Neutral). If your vehicle is equipped with a manual transmission, the clutch pedal also must be depressed. The 4x4 Low indicator will flash continuously until these actions are performed by the user. This vehicle is equipped with a non-synchronous low range gearset which will not allow the transfer case to shift into 4X4 LOW if vehicle speed is above
5 mph (8 km/h). It is recommended that a shift to 4X4 LOW is performed while the vehicle is rolling at a speed below 5 mph
(8 km/h).
The 4WD system:
• provides 4x4 High engagement and disengagement while the vehicle is moving.
• is operated by a rotary control located on the instrument panel that allows you select 2WD, 4x4 High or 4x4 Low operation.
• uses auto-manual hub locks that can be engaged and disengaged automatically based on the 4x4 mode selected.
• auto-manual hub locks can be manually overridden by rotating the hub lock control from AUTO to LOCK if desired.
• automatic operation of the hub locks is recommended, and will increase fuel economy
• For proper operation, make
sure that each hub is fully
engaged and that both hub
locks are set to the same position (both set to LOCK or both set to AUTO). To engage LOCK, turn the hub locks completely clockwise; to engage AUTO, turn the hub locks completely counterclockwise.
