I feel stupid asking this but my OCD is killing me right now. I bought a 21 Platinum last saturday. Yesterday going down the road about 45mph I decided to switch between the different drive modes to see what each of them were.

Now i'm just finding out that some modes like rock crawl, mud/ruts, etc., should not be used on dry pavement and could bind up the rear diff. Did i mess anything up? I didn't stay in any mode more than a few seconds before finally cycling back to normal. I definitely didn't feel or hear anything weird and I'm pretty in-tune with that type of stuff.

Somebody please ease my concerns lol

 

you're fine. Just remember, some of the modes will take you to 4WD. I go to Sport from Normal mode a lot in my truck as I am driving. As long as you are going past one mode to get to another, the truck doesn't do anything as you roll across the various modes until you stop on a mode for a couple seconds-

 

Yeah i think i'm most concerned with the possibility of my e-locking diff got engaged. Do you think i have anything to worry about there?

 

It won't engage over a certain speed. You're fine.

 

I cannot say conclusively, but I am pretty sure you can't lock the diff while moving. I haven't tried it on mine. That is one thing, that spin **** controls the modes, then the buttons around it are for 4WD modes and then the center activates the locker! Takes a little getting used to!

 

Thanks guys

 

^This. You should be all good.

 

I have that exact same truck. No worries! It won't let you do radically stupid things.

 

Also, it’s perfectly fine to go into 4H when going straight on pavement. It’s good to exercise the 4X4 system once a month for about 5 miles, if possible. If you are going straight there is no risk of biding. This happens when you are turning on dry pavement.

 

No worries, especially if you were driving straight. The real binding in a locked rear axle happens when turning (sharp).
