Transfer Case broke....Replacing with Atlas

Driving down highway at about 65, all of a sudden got a nice loud vibration from under the JK. Immediately pulled over and looked underneath....Fluid pouring from my transfer case.

So The t-case needs replaced and I am going with an Atlas 2-speed 4.3:1 ratio.

Anyone running one of these?

I saw a pic of someone who installed an atlas, I believe it was a 4 speed, and it had two levers, does the 2 speed have two or just the one?

You have pics of you GF's installed, inside and/or underneath? that would be a great help.

I think the four speed transfer case has three levers and the two speed as two levers.

Love you brother and you will always be my hero!

I'd be interested to know why your t-case failed. The main reason I've heard of t-cases failing on the highway is from a bad front pinion angle cause excessive vibration and a kaboomed t-case.

I did have some vibration at highway speeds.
I have Tom Woods driveshafts front and rear.
Lifted 4", with 35's.

I dont think the t-case failed, something caused it to fail. Prob vibration.

Check the front pinion angle, if it's much over 6 that could well be the cause, and will need to be corrected.

What is, and how do you check the pinion angle? and how would it be fixed?

Adjustable control arms or cam bolts if you don't have adjustable control arms.

One stick for the front, one for the rear. An amazing amount of fun! The 4 spd doesn't necessarily have three sticks. They also have an electrical shifting option for the low- super low range. Go with the 5.0 gearing instead of the 4.3.
