Maybe I should have given a little background! I have a 2004 WJ with Quadra-drive....this system uses Vari-Lok Axles, for the WK they went to Limited Slip Axles so the response time of Quadra-Drive to decrease. While I have no form of ESP or traction control system on my Jeep, it used to always break the rear loose. Without her ESP engaged, Quadra-drive will have some tire spin that could cause a fishtail, however it will always right itself. Now if she as Quadra-Trac then that is a different story there is no power transfer with that system, if you spin the ESP should catch this.
