That escalated quickly. :cwl:

On a serious note, @sardog12 is correct that even wet pavement is a bad idea. You need snow, ice, or mud to provide enough slip to let the front axles prevent binding.*

*The exception to this rule is if you have the optional full-time t-case on the Sahara

You obviously donĀ“t know what a differential is. A transfer case (thatĀ“s what the t stands for) may have or not have a differential.....buddy:like:

No, it is not called locked center differential. Part time 4x4 like the sport or the Rubicon donĀ“t have a center differential. Some AWD systems have a center differential and that one can be locked.
Everyone can learn something today.

ā€œMany transfer cases also have a differential. Just like the differential in the axles, this allows one output to spin at a different rate than the other to avoid driveline bind on hard surfaces. More on that in a minute....ā€

Some do but the fact is that the only ones in a Wrangler that do are the ones in the Sahara. @Torero is still correct in that part time 4wd like the ones in the Sport and the Rubi do not have a center differential that allows for driving on the street except in extreme cases where traction is very little.

No heā€™s arguing only Awd systems have it.

Orrrrr... if your tires are shot. Of course, that'd mean that you'd have enough slip to let your front axle prevent binding. And you'd be a bad person for abusing a Jeep like that. Yeah... Put good tires on your rig, and enjoy yourself.

You can call it by whatever name you want to (all wheel drive, full time 4wd, active 4wd, etc...) but essentially, he is correct in that the only transfer cases that have a center differential are those meant to be AWD. Even on the hybrid Sahara transfer case, when you lock it in to the true 4wd low mode, the differential is not operating. It only operates in the AWD mode. You would not sensibly drive any of these cases on the street in 4-low (command-trac, rock-trac, or even select-trac) unless there was extremely low traction because they do not have an operating center diff to allow for slippage between the axles.

@sardog12 let it be. @XJrider argues any post of mine. He is a loyal follower of me. Itā€™s a hobby for him. :giggle:
