Hi, so i i just purchased a nice set of 33 inch tall tires and installed them. so my problem is the gas mileage. I am still a Senior in high school and i dont have a big build budget. so i was wondering, since i ordered parts for my rear, can i just re gear my rear end first without having to disconnect the front driveshaft. I quickly took off the front yoke connection and it seems to be free spinning inside the transfer case. so theoretically, as long as i drive around in 2wd i wont blow up my transfer case. i am going from a 3.07 to a 4.56. it would be great if i could do this because i am on a tight budget.
