is there any quick and easy ways to tell what ratio a diff is?

in reference to a 4x4 front diff, with sump plate removed. would just be handy to know exactly what it is!

something like count number of teeth on the crown wheel and devide it by the number of teeth on the front pinion
i sure thats it

check the edge ov the crown wheel on the early mk1 mk2 diff it was writen on crown wheel

 

Count the teeth on the crown wheel and divide that by the number of teeth on the pinion

Mark

 

so i was right

 

If you can see the Crown wheel (big gear) and Pinnion (small gear),
Count the teeth on both gears:

Ratio = Crown wheel divided by pinnion.

Other wise jack up one side, so the other wheel is still on the ground, (if its L.S.D jack up both sides) turn road wheel 1 rev and count how many revs and part revs prop shaft turns = Ratio .

Tooo slow posting

 

The Diff is currently out of the car so can be counted on a bench.

will have a look and see how i get on...


... Cheers

 

you should have left by now
