Dose Esp have some thing to do with Limited slip differential ?
Hi jeepers 
I have 2dr jeep wrangler JK 2008 ( Sport ) I dont know if u guys have ( Sport ) in US
but it has same differential and suspension of Sahara
I have turned of the ESP completely in 2wd and 4wd using the loooong method of turning the stearing wheel to left and push the buttion then turn it right ... etc
I have noticed one day that if the engine is on and the jk is lefted and if you spin one of the tires with your hand the other one will spin in the opposet direction !!!!!
in Meddle east all jeep wranglers comes with limited slip diff even my friends tried that with there jeeps the both tires spin in the same direction not like mine !! why mine is acting like open diff !?!?!? is that because of the ESP OFF thing ? my friend still keeping there esp on : ) thanks in advance.

ESP has nothing to do with the limited slip differential.
If both rear tires are off the ground, and the transmission is in neutral, the tires should spin in the same direction when you spin one by hand, and you have limited slip that is not worn out.
A worn out limited slip differential will act like an open differential.

yeah they are different but ESP acts much like trac-lok and if the ESP is malfunctioning could cause issues - may just need reprograming... also on a side note: NEVER turn ur differential fill plug in more than "hand tight" an over tightened fill plug on a Dana 44 has disastrous effects!
The torque for the differential fill plug on the JK Dana 44 cover is 25 ft./lbs.

good luckI can see your thought process is a little different from mine. I don't understand why you would do that.
This is a copy/paste right out of the factory service manual:
2. Install cover (1), identification tag (3) and tighten cover bolts in a criss-cross pattern to 41 N·m (30 ft. lbs.).
3. Fill differential to specifications.
4. Install fill plug (2) and tighten to 34 N·m (25 ft. lbs.).
