Okay my jeep is wrangler jk sport. Has the islander package. 3.73 gears and LSD in the rear.

I am confused on how 4wd actually works

You have 2hi, 4hi, and 4low. Is in any if the mods the front axle locked or is it like a open dof

 

Dif*

Does the front have LSD since the rear dif does? Or when your in 4wd and say the front left tire just starts spinning that's it or does is transfer power evenly between left and right tire

 

Your front axle is always an open differential. It doesn't have a locker or limited slip.

However, in 4wd high or low, the front axle has traction control which applies some braking to the spinning wheel, thereby routing more torque to the other wheel. The rear axle also has this in any drive mode.

 

It is still an open differential. In 2Hi, only the rear wheels get power. In 4Hi, all wheels get power. In 4LO, the 2.72:1 ratio kicks in. With Rubicons, the 4:1 ratio kicks in. 4LO is good for crawling and moving slow or when you need power to the wheels without spinning.

 

Appreciate it! Are there any options to making the front a locked diff when in 4 hi or lo I am adventually going to rehear and while I'm in there want to put lockers on the front and rear.
How would rear locker work when you have lsd

 

Is there any benefit to having the limited slip rear differential option if there is traction control?

 

Thanks I know understand it better just wasn't sure how it worked ecactly

 

I would assume what if you have traction control turned off?

 

I believe the portion of traction control we are talking about remains active, even when ESP and traction control are turned off in the normal way.

Limited slip is good when it works, but it wears out after a while and the differential acts like an open diff again.

 

Our jeeps have brake lock differential BLD. Do a search on that and you will find some good info. Last night we got 6" of s is here in NJ. This was my first experience driving the jeep in snow. I was amazed how well it did in 2wd. The traction control and BLD does a fantastic job. I never felt the need to engage 4wd.
