Ok and how would you say it performed? Does it do a good job at creating traction? How is it in the rain?The Full Time cases aren't AWD, they are Automatic 4wd Hi. No center differential.
Runs in 2wd until slippage is sensed, then shifts to normal 4hi.
Not sure that's entirely true. From what I understand, it's a wet clutch pack than can progressively shift up to 50% torque to the front wheels. Basically like a backwards Haldex that you have the option of locking into 4-Hi.The Full Time cases aren't AWD, they are Automatic 4wd Hi. No center differential.

The durability issue is an off-road thing. 4WD Auto has CV joints on the front axle instead of U joints. CV joints are stronger than U joints, however they require rubber boots to keep dirt out of the joint or they will get destroyed quickly. Those boots can be torn by branches/roots on the trail. CV joints are also near impossible to repair or jerry-rig on the trail whereas U joints can be repaired or rigged to limp along. For those reasons most find U joints preferable on an off-road vehicle.The only argument against is perceived durability - that nobody thus far has been able to show here, unless I've missed it - and cost. Otherwise, choose either mode with the shifter.
So would you say on road in say a snow storm an audi with awd would be far superior to a JL in 4 hi or 4 auto?4WD Auto is not AWD. Do not equate the two. They operate differently.
AWD distributes power to all 4 wheels even if they are spinning at different speeds (which happens in every turn or curve in the road). AWD is superior to 4WD in slick on-road conditions.
4WD Auto is 2WD until the rear tires slip, then 4WD HI is quickly and seamlessly engaged. It returns to 2WD as soon as the rear tires stop slipping. 4WD Auto exists to mitigate how 4WD HI can cause the driver to lose control in higher speed turns & curves in slick on-road conditions and skid off the road. 4WD is far superior to AWD in off-road conditions, which is why the JL doesn't have AWD.
Yeap. For daily road driving, at speed. The audi makes your life as a driver a bit easier.So would you say on road in say a snow storm an audi with awd would be far superior to a JL in 4 hi or 4 auto?
If clearance, vehicle weight, and tire tread/compound were removed from consideration, I'd say yes.So would you say on road in say a snow storm an audi with awd would be far superior to a JL in 4 hi or 4 auto?
Understood, that's the speculation I've heard - but there are no branches growing on the legal, established trails I visit in CO, Utah. I've also torn many a CV boot - it didn't disable the vehicle, not even close, it just means you need to fix it soon - takes many more miles before water and debrise get in there and things start making bad noises. Worst case - that axle gets destroyed - I still don't see it preventing you from driving the vehicle.The durability issue is an off-road thing. 4WD Auto has CV joints on the front axle instead of U joints.

This isn't really an Audi vs Jeep thing, it's AWD vs 4WD (Auto or HI).So would you say on road in say a snow storm an audi with awd would be far superior to a JL in 4 hi or 4 auto?
I'm in the same boat in UT. How often do you check your CV boot for tears? Most discover torn CV boots through symptoms, not by identifying the cause. If you do any rock crawling, you can count on breaking a joint eventually. A broken U Joint is much easier and cheaper to deal with.Understood, that's the speculation I've heard - but there are no branches growing on the legal, established trails I visit in CO, Utah.

4Auto is default, I believe it's the same Rock-Trac FT case (MP3022 4:1) with 2 hi left off the selection.I'm confused here, never had to deal with AWD or full time 4WD.
With the 392...is it full time full wheel drive or does it only put power to the front wheels under certain circumstances?
Is 4H the default mode?
