Question 2013 4X4 auto

So the snow flew yesterday and the roads were stupid icy. Im just wondering exactly how the 4X4 auto setting works? what are some pros or cons compared to using 4X4 lock? Will the auto engaging and disengaging wear anything out?
Thanks.

I believe 4x4 auto allows for limited slip when turning so you can use it on the highway\dry roads.

4x4 Lock does not and is not intended for use on roads or dry surfaces.

I always thought AUTO acted sort of like an adaptive AWD in that it uses 2wd until the wheels start to slip at which point it would engage 4wd to compensate for the loss of traction. I could be wrong though....does anyone know?

the system will have the 4wd system engaged but i do believe when one of the wheel sensors trips from a wheel slipping and turning faster than the rest it engages the front driveshaft to enhance traction and control. if it's the same type of system used on the jeep grand cherokee it's a great system. for 10 years my grand cherokee would be put in part time 4wd in fall at first snowfall and stay there until spring. it always worked flawlessly. dont use full time 4wd unless your in a snow storm or off roading part time 4wd is designed for adverse road conditions. not for high speed driving.

Yep, auto is safe to take up to hwy speeds. It should be somewhere in the manual as well, though I think they tell you to try and limit it to 55mph.

Correct me if I'm wrong but from what I understand it works sort of like an electronic auto locking differential but its the transfer case rather than the diff, meaning that in 4wd auto it will be in 2wd until the truck senses slip. Upon sensing slip in the rear wheels the front wheels will engage. It will then disengage to avoid binding the transfer case when your rear wheels regain traction.

That's why its called full time 4wd, because you can have it on full time, even on dry pavement and it will not damage your 4wd system. Part time 4wd can only be used when you are in slippery conditions because turning with it engaged on dry pavement will bind your transfer case. The 4wd lock and 4low settings are both part time settings. I believe the manual says not to use 4lock or auto above 55mph and not to use 4wd low above 25mph. With the 4wd auto you could probably go as fast as usual as long as you're on pavement though. I personally think 55 is too fast to be driving in situations where you actually need 4wd.

If the auto is anything like GM has had for years. It will stay in 2wd until it recognizes 4x4 is needed. I sadly don't have this option.. 4x4 high and 4x4 low ... The auto is a great system to have.

The 4x4 auto is one of the reasons i sold my 1500. The 4x4 auto works good like it should. but in trucks with the 4x4 auto option the 4x4 lock option doesn't actually lock like it would in trucks without the auto option, its the way the transfer cases are set up.

What do you mean the truck doesn't actually lock?

From my experiences, the 4wd lock means your transfer case is "locked" into 4wd and is constantly transferring power to your front diff just as it is your rear. When the snow is really flying or roads are extra slippery, I use this option.

4wd Auto, as others have stated, is automatically transferring power to your front wheels as it senses your rear wheels slipping. I find in my ram there is a pretty solid delay between rear wheel slippage and front wheel engagement. You can get pretty squirrely before your front wheels start to pull and straighten you out. Not really sure of ratio of rear spin to 4wd engagement. I use this all winter when it's not super bad out because you're basically driving around in 2wd unless you start to spin.

I can't see any issues with exceeding 55 while in auto.. the only problem would be if you somehow started spinning and the 4wd engaged at these speeds. For one it would cause some pretty unpredictable results and two I'm sure it'd be pretty stressful on your drivetrain at that speed, especially if you then caught traction again.

Just my 2 cents...
