Rubicon Rear Differential

Does anyone know if the Rubicon's rear diff is limited slip when not locked?

No its full open

Okay, thanks.

Okay, thanks.

I am pretty sure all JT, (including the Rubicon) get brake lock differentials (fake lockers achieved via applying brakes to the side without traction). Might want to fact check me on that.

This is true, and it works quite well. In reality, you could say that all modern cars have this, in the form of traction control.

That's all part of the traction control sway and yaw control. I'm interested in how well it works. My Silverado has it along with a limited slip and it can be counter product with the two systems working. Had a few instances when the rear end would lock and the truck start moving only for the sway control to kick in and apply brakes but once the rear was lock it stopped the axle as a whole and stopped all momentum.

The BLD system on Jeeps is programmed a little differently than your average traction control systems. I have found that it works fantastic offroad and I prefer it over the Trac-Lok.

The TJ Rubicon is the only one that had the Trac-Lok and Tru-Lok combined in the differential.

Okay, thanks. Any experience with snow covered roads?

So . . . the Sport S or Overland don't necessarily "need" to have a rear locker, because it's, lets say; muddy or sandy slippery situation arises, the computer will "take care of "business" sort of like in my WK2 Trail Rated in "auto mode" ?
Pardon my lack of expertise . . . I'm just a moron wanting to learn, so that I will feel confident on the trail in a Sport S or Overland without the rear locker option ! OR, should I play it safer and get the regular axles & the Locker Option ?
Most of you guys know I'm not your Traditionally "wacky" off Road "Mad" Crawler (kidding of course) . But Occasionally I'll find myself in a difficult to turn around situation of Mud or sand or bush lined narrow trail (in the WK2) - hopefully a JT (longer) by years end .

Hi - I believe JT Rubicon does not get "brake lock differentials" as I think you described. Rubicon's have electronically actuated selectable lockers. They are open until the mechanism is activated and the differential is locked in place. See 14:19 of this video (explaining Eaton e-lockers which are mechanically the same principle). Rubicon axles do not use the brake system to simulate locked differentials. I believe what you are describing is how modern traction control system works and I believe that is how a JT's traction control system works when in 2H and 4H.
