How to check differential gear ratio?
 

Is there a way to check this w/ out opening the case? Like turning the wheels and checking the revolutions of the driveshaft?

Spin both stubshafts the same direction 10 turns and count driveshaft revolutions. It will either be 39, 41, or 43.

count the pinion teeth and the ring gear teeth. divide. whoops, what Sav said.

you guys are pros. this took me 2 seconds to search.


yessssssss
