Dertermine Rear End Gear Ratio
Is there a way to determine what rear end gear ratio (4.10, 3.73, 3.55) etc is actually in your truck. Sticker on glove box says 3.55 but I have reason to believe that the gears may have been changed...

there's always the fool-proof way of marking the driveline and counting the revolutions while the wheel turns one time.
