google brings up the weirdest threads...works better then the cherokee forum search... i have a powertrax no slip in mine and the thing works wonders. and no it doesnt always unlock in a corner. as long as your foot is off of the gas pedal, it will unlock. if you hit the gas hard, it locks. if your easy on the gas, it will stay unlocked allowing the wheels to turn seperate speeds. biggest time i notice it is pulling into traffic from a side street. seems like left is worse then right. if you hit the gas hard to pull out into traffic, it does lock and you hear the tires chirping the whole time your turning. i personally enjoy the chirping. my tires might not, but i think its fun. works wonders when you climb over stuff or pushing through mud. currently running 33s on 29 spline

 

So I'm still learning about differentials and lockers. I bought my XJ with an Aussie in the front and it's great on the trails! I don't really know it's there when driving around town, although I think my wheels are hopping or something when turning. I was wondering if it'd be a good addition to add a Powertrax or something similar in the rear. Would I have better traction in 2WD while on the road? And are there any cons to being locked front and rear on the trails? Is turning harder in 4WD?
