Buford Well-known member Sep 4, 2010 #2 A whole lot more than three, depends on what year car or truck you mean...

01aford Senior Member Sep 4, 2010 #6 I heard the ratio was stamped on the housing. I have one that says 934
Ken/Alabama Well-known member Sep 4, 2010 #7 That would be a 3:78 ratio. The 9 represents # of teeth on the pinion and the 34 the ring gear.
