How about counting the number of turrns of the input flangethat are required for one complete revolution of the output shafts (averaged if it's different for each side)? Would that do it?

if you take the cover off the back there should be painted numbers on the crown wheel (think thats the big gear bit) )

If there aren't, and if he's got the cover off anyway, then if he can see, or feel with something, the pinion, he can just count the teeth on the pinion and the crownwheel, divide the latter by the former and get the ratio.

Easier just to turn the input flange and count the turns needed to get the outputs to turn one full revolution, though.

This was answered yesterday when you posted it

I don't think you will get a different answer by asking the same question elsewhere on the forum.

If you have major concerns about your diff a little more background info would be helpfull

As it stands You appear to have a 7" sierra diff that has a ratio of 3.62-1 & is fine for the Roadster

I have merged all three threads into one as this topic is starting to get messy.

I just found this on the "wide world winternet"
For those who still wonder how it works. They'll never have to ask again.

Hope this link works. ;-)

That explains the Differential Drive which is one component of the final drive unit. the other is the Crown and Pinion gears that Provide the Drive ratio.
