To simplify, if the road is white, 4H. If it isn't 2H. If you can see the pavement, you Jeep will get you around just fine in 2H. Also, congrats on your new ride!!!

Yes, you are going to get blasted. So sit down, hold on and enjoy it.

To answer your question, unless you drive a 392, your Wrangler is in RWD until you decide to pull that lever next to your right knee and engage into 4WD.

Most Wranglers have the Command-Trac 4WD system, which is a strictly part-time 4x4. Meaning, you have to be on slippery surfaces, like loose dirt or snow-covered roads, to use it.

If you own a Rubicon, it will have the Rock-Trac 4WD system, which works similar to above but is harder to engage.

A smaller number of Sports, Willys and Saharas come with Selec-Trac 4WD, which has 2WD mode, Full-Time 4Hi Auto, and Part-Time 4Hi and 4Lo. Selec-Trac can be used all the time in either 2WD or in Auto mode.

An even smaller number still have the Rubicon’s full-time 4WD, with modes similar to the Selec-Trac.

Rubicon 392 comes with the Selec-Trac, but with 2WD mode disabled.
My Rubicon 4xe came with Selec-Trac not Rock-Track, I think they all do. With 2wd enabled. And I have a buddy with a Rubicon Pentastar that has Selec-Trac (and CV joints in the front). I think they did strange things at the height of the pandemic supply problems.

My understanding is that the only Wrangler with 2WD disabled is 392.

Agreed. I said mine was enabled. The Tazer JL can enable 2wd in the 392 according to the manual. I think it's factory disabled to protect the driveline and rear end from all that torque. The 4xe computer limits torque in 2wd.

This would be true if your axles were locked, otherwise a 4x4 is a 4x2.

I will say, I understand what you're saying, and the reasoning. When locked and driving on road speeds, especially, you'll find a 4x4 to be a crab-walking, low-side finding death machine, haha. The open differentials allow the vehicle to hold the line and not push sideways.
And 4WD (no lockers) does the same thing on winter roads, just to a lesser degree. In 4WD the transfer case locks front & rear. It's still a locker doing the same thing on a different axis. It's more subtle because it's only forces one tire to skid. Whereas if you add axle lockers to that you're forcing 2 or 3 tires to skid. And you know the results of that.

While only having one tire forced to skid in 4WD is better than having lockers on, it's also more deceptive because its effects are subtle until it bites you and spins the vehicle around in a curve.

You should read the owners manual and not take the potentially dangerous advice of strange folk on the internet.

Anyone arguing for the use of 4WD on pavement is trying to kill you and your family.

Man, you guys talk like if you put your Jeep in 4H on the road, it'll cause an undetermined but catastrophic failure some time in the future. Why doesn't the OP do this- next time it's raining and you're driving about 35 mph, put it in 4H and see how it drives. Then when you're done doing that, put it back in 2H.

Later, go into a large, empty parking lot and drive about 15 mph. Put it in 4H and steer more than you would have when you last put it in 4H back when it was raining. Maybe slow down like you're taking a turn on the street while in 4H, and see how it drives. Then when you're done doing that, put it back in 2H.

Take all of this knowledge that you've gathered, and use 4H when you deem necessary.

Actually probably won't be too long before Jeep starts calling it $WD.

I kid ;).
Nice, never even noticed it! It kinda looks like when I see that other brands are starting to withhold features that are installed and functional on vehicles behind pay walls Makes me real, extra angry!

Oh, you wanna go fast in your sports car? Pay us an extra $150/month and we will disable limp mode on your brand new vehicle.

I say Get absolutely f@#$%d!!!!!!!!!!

With winter coming up, I was wondering, is my Jeep always driving all 4 wheels? Or is it 2wd until I engage the 4x4?
This was your question regardless of how sideways the answers went for you.
Use 4 wheel drive when it is slippery out and you feel you will need it - this is why you bought a 4 wheel drive vehicle so use it and be safe
There will be days when you will be shifting in and out of 4wd a lot due to road conditions changing as that's how roads are in reality regardless of our "resident experts" here.
If you end up on dry pavement in 4wd it will not destroy the Jeep and you may not even notice at all when going straight but shift into 2wd anyways
If your going down a slippery hill - please use that 4wd as I'm not sure if that was an evil joke earlier or what claiming it is more dangerous going down a hill in 4wd but - damn !
Generally drive in 2wd but if you feel like you need 4wd due to conditions then always do so and if its still unsafe - slow down until its better ?
If advice here on the forum sounds bad - search out reality and use your own sense
It sounds like your first true 4wd vehicle so you asked ?

Yeah, what kind of advice was that to not use 4wd on a slippery hill???
Just keep in mind when in 4WD that you should be driving with more caution and more gradual turning and you'll be fine
