I have a 2005 grand cherokee 5.7l hemi. I love it more then words can describe. The awd system is amazing and its a blast in the snow. But i have a couple of questions (1) how do i disable the awd and leave it on rwd? (2) will disabling the awd improve emissions?

 

change the transfercase

 

wouldnt that give me the option to go to 2wd and 4wd? ive heard that all you have to do is disconnect a plug or a wire that powers the front wheels... i dont wanna waste money on a transfer case

 

if im not mistaken allwheeldrive is only 1 tire gets power untill its needed elsewhere. 4wheel drive is when all 4 tires get power at the same time. alittle bit of a diffrence. so no it wouldnt save you gas money if you disconnected it. it would probably make it worse cause the computers are programed for awd. not only 2wd.
i could be wrong and id let someone with more experience chime in.

 

you do make a good point because i do think the wheels are independent.. but im not 100% either..all i really want to do with the 2wd that im looking for, is a sick burnout and some fun.. the emissions question was just outa curiosity because if my emissions would be better, during the summer id leave it on 2wd to save me some gas cause she does guzzle it down pretty damn quick!!
