If you have the switch beside the steering wheel you won't have to lock your hubs. Its a electronic 4x4.

To engage in 4 high its best to do it when stopped
-40 to 55 is ok! (nothing higher)
&

To engage in 4 low you have to be in Neutral and stopped!
-10 to 15 is ok! (nothing higher)

 

"Some say once you have it locked in, put it into reverse and drive back a few feet then put it in drive and on your way. Just ensures a good lock in of the 4x4."

I always understood that you should back up 15 to 20 feet after disengaging 4x4 to ensure the hubs are fully disengaged. I have never heard of backing up to get a solid lock-up going into 4x4. Any input from the nuts & bolts guys?

 

I've heard of this also.

 

Hi Bubba
This website should help you about 4x4 systems.I rarely put my truck in 4x4 except when im doing work around the property here.2wd 95% of the time here.If you keep your truck in 4wd all the time,chances are you will break something.Going in a straight line is not so much a problem,but when you turn,the wheel speeds on the front will be different,causing big stress on the transfer case& causing the thing to go BANG!Blown xfer case!
There are really no REAL advantages in keeping it in 4wd on dry pavement.The engine has to drive now two driveshafts causing your milage to go south.Go to this website below&this will help you about the system in your truck.Best wishes,Pete
