Picked up this 2008 Cherokee for my wife last year, and was excited to drive it in the snow. I thought it was full time 4WD, but noticed that they front wheels weren't spinning as my wife was driving it in my back yard and got it stuck in 4 inches of fresh unpacked snow. I managed to get it unstuck by clearing all the snow from under the rear tires. Is there anything special i have to do or is it possible that the 4WD is not working?
Please dont be too harsh on me, I am new to 4WD and the jeep community.
Were you flooring it? QTI can only send power to front axle if Brake Traction Control System (BCTS) is able to stop the rear wheels from spinning. I've noticed on my QTI that in stuff like that, I use less (and constant) throttle and let BTCS "dig" its way out. If I just drop the hammer, it pretty much just spins the rears. Also, age/type of tires matter.
Turning of ESP, helps me get out of deep snow and when all 4 wheel are stuck on ice.
Tires are a factor as well... Ive got Winter tires (Michelin X-ice 2) traction sucks with 5inches of snow vs My All-Seasons ( Firestone Destination AT) which I find better for snow traction. But I would keep my Michelin for Ice togh...
