Try this site. I tried just putting your rearend code in, and it would not work. Maybe it will work if you put your vin number in with it.

Just jack the truck up and put in neutral, Mark the drive shaft and the tire, Turn tire one rotation and count the number of times the driveshaft goes around. 3 and a half
turns = 3.55:1 4 turns and a couple degrees = 4.10:1 Someone may have changed
the ratio and left the stock tag, you never know!!
