my brother has an '05 QCLB CTD with a G56, 285/70r17 cooper atr's. i have an 07 QCLB CTD with a G56, 285/70r17 cooper atr's. both 3.73's. why is at 2000 rpm i'm at 75 and he's at 65. the speeds are exact, but i'm at right around 75 at 2k and he's right around 65. what's the deal? is it gearing in the transfer case?
this is very interesting, he bought from the lewiston dodge dealership back in late 05 or early 06, told him it was 3.73. where does a guy look to figure this out. he's still under waranty if that matters, should the dealership fix this? because he's looking into putting higher geared rearends in it now for fuel mileage.
