Transfer case tutorial with accessories?

[Arctrooper0202]

so My family has owned our rubicon for a year now and we are kinda eager to take it off road however we would like to fully understand it’s capabilities. We would like to understand the transfer case with 4 high and 4 low, differential lockers, axel sway bar, and the steps take prior.

Depends on where you're going. Recommend hooking up with someone who's done it before (local club or parks?)

Fire roads, just put it 4 wheel high and enjoy carefully, minding the terrain and travelling on unknown areas.
Rougher trails with lots of larger rocks, air down if you have a proper compressor to pump them back up for the trip home), disengage sway bar (select 4 wheel low and keep speeds down)
Slow and steady through water hazards (always hard to resist) helps to have a "Hugo" leading (as in Hugo first)
Locking diff has several negative effects on steering and should only be used when stuck or for other conditions where powering both or all wheels prevents getting stuck.

Note: A Walmart compressor will burn up trying to inflate 4 Rubicon tires from 15 to 38..
I'm sure others will pipe in..

Thank you! Can you use lockers in 4 high or only 4 low.

Thank you! Can you use lockers in 4 high or only 4 low.

Only 4 low, the car wont let you turn them on in anything else, also dont forget to shift the transmission into neutral before trying to shift the transfer case into 4low.

In another thread I wrote up an explanation of how the lockers function. You might find it helpful.

Below is a good video explaining the function of a differential.

An open differential is where the wheels are free to turn completely independent of each other (axles are 0% locked together). A locker, or locked axle as it is called in the video, is shown at 2:45, where the left and right axles are locked together 100%. A limited slip differential is one that functions as an open differential under normal conditions, and a partially or fully locked axle when certain conditions are met. It limits the slip between the two axles somewhere between 0% and 100%.



For off road, an open differential can send all the power to a tire with no traction, since it would have the least resistance. The limited slip should eventually figure out that the axles are turning at different rates, and decide to partially or fully lock the axles together, giving the tire with traction some power. A locker sends power to both tires all the time, meaning there is no waiting for the limited slip to "kick-in".

There are many different kinds of limited slip differentials, and all have different properties of what makes them lock and how locked together the axles become.

*edit: removed incorrect information about optional Sahara transfer case
