So the door jam sticker says axel 34 which when I looked it up its gearing for 3.73. So I'm assuming that is the gearing left? Or would quigley change the gearing when they did the lift, bigger tires and all that? I would guess that I will have to look at the axel itself when I see it in person this weekend. Also if it is the stock 3.73 gearing with the 4" lift and the 295 65r18 tires should that gearing be changed? What would that gearing do for driving/milage/strain on the engine?
Just took a picture for all you non-believers out there. I dont have a full loaded down Sportsmobile, just a stock 2014 E350 5.4l 3.73.
I'm curious how these factory dash mpg calculators actually work. It the very old days it was a wild-ass approximation based on engine vacuum and maybe speed...........Are post OBDII-fuel injections ones accurate?
