Proper way to check Rear Diff Gear Ratio??
Finally go around to doing my rear diff oil change today and did the tire spin while counting the axle spins to try and figure out my diff gearing.
I tried the one full rotation of the rear tire and counted my drive shaft rotations which didn't even get around twice which I thought was weird. I then googled a video and one guy said you have to rotate the rear tire 2 full turns to find your gear ratio which seemed to work much better. By using the 2 full turn method, my drive shaft rotated 3 full turns plus a sliver. I'd guess that to be 3.08 or 3.10 gearing. Is the two full rotation the proper way of doing it?
