Hello, this is my first post as I just registered today, I was curious to know what kind of mileage increase I could expect if I were to install a 3.54 rear axle in my 1998 Nissan frontier in place of the 4.33 axle I have now, my engine is a stock 2.4 Dohc with a four speed auto, my truck is 2wd and I am running 235 75r15 tires in place of the factory 215 65r15.
