I have a 2003 Ford Ranger with a 4.0, automatic, extended cab and 4 wheel dr. I get terrible gas mileage, 15 or16 mpg. The door jam tag says it has R7 differential, which 4:10, something you would need in a log truck! Has anyone ever changed the ring and pinion gears? I have been looking and I can not find any lower than 3:08. I would like to get it better, Rock Auto has a 2:73, but it's for a 7.5 ring gear and mine is a 8.8 inch.
