So if I'm understanding correctly, the new BMW M5 is a 4WD rig, not AWD, because you're able to select 2WD mode? Bet it looks sick with 35's.

It is the same in terms of the settings, though, and I was responding to the comment that they've always been troublesome. They have not, at least in my own experience and knowledge of others with both older and newer Cherokees and Grand Cherokees.
I was not referring to all of Jeep’s transfer cases. The old NV242 was chain driven and reliable. You cannot compare them just because Jeep uses the same marketing name. I was only referring to the clutch pack based transfer cases that are known to be troublesome

Aldo is arguing that selectability is the distinction and is the reason he called me out. I used AWD instead of writing out full time 4 wheel drive in an above post. Functionally the setting are the same. So when someone uses the term “ for the record” or other “l’m smarter than you“ BS terms I tend to double down on my point that the FUNCTION is the same. But hey, let’s add another bit of confusion To argue about. Y’all argue about the WK2 selectable dial between auto, sand rock and low. Meanwhile I’m going wheeling in Uwharrie.
So you get argumentative because you think a phrase I used means something else entirely, and then you double down on an argument that has nothing to do with with anything.

Yeah. Gotta love the Internet...

No, the distinguishing characteristic of 4WD over AWD is the ability to engage part-time 4WD, 4-Lo in particular.

See? It doesn’t take much for some to get lost...

Ok so having 4-lo is what separates 4WD from AWD?

Let’s say “yes” for simplicity.

@DanW posted a video above that shows the key differences between the two.

OP are you able to sleep now? or did it get worse?
I still wish I would not have ordered it, but am leaning towards just accepting that I did. I like durability, and I feel like the transfer case especially will be weaker. Also not a fan of CV boots, not so much the CV itself.

My experience with full time 4wd is with the Hummer H2 and H3 (adventure with e-lockers).

The H3 might be the closest comparison to the JLU in size/weight, it's a beast in the rain and snow. I honestly can't think of anything I ever drove that felt more planted on ice/snow/rain covered roads.

I would stay with the full time AWD.

Does the ALL WHEEL DRIVE optioned transfer case still have a FAD?

Yes. My understanding is that ALL JLs have a FAD, regardless of trim or 4WD system.

That’s a good point.

My Sahara too feels much more sure-footed in 4A in a way that you’d have to drive it to know what we are talking about. Even in perfectly dry driving conditions.

I’m just too cheap to leave it engaged all the time. But the moment the weather starts to turn in another month or so, the Selec-Trac goes into full-time mode until next spring.
