Re: gonna find out my rear end ratio....

What you do is to turn the pinion yoke (driveline) exactly one time and count how many times the tire goes around. It's actually a pretty darn accurate redneck way of finding the ratio. Chalk or mark the tire somehow.

If it's goes around 3 1/2 times, it's about a 3.50

If it only goes around a little more than 3, it's a 3.07 or 08

I like it when they go around 3 3/4's times cuz that's your 3.73

and so on......
