Diff Ratio

Not if the diff is a single spinner, It will give you a rough idea.

It may have a tag on one of the nuts, that connects the center to the housing.
The rpm at 100km/h will be close to what diff ratio you have.

Try tuning both axles at the same time, and watch the pinion flang.
Or quote the number/letters on the outside. I can check the centers i have here.

Thanks Maxrs

I tried looking for the tag earlier , that would have been nice , the diff is out of car so I cant try the 100 km thing either

When I tried earlier , 1 turn of the wheel studs was roughly 2 turns of tailshaft end so no closer to an answer
If worse comes to worse I will pull it out , I just want to know what it is to know if to keep as a spare for mine or get rid of it

Cheers for the email

try turning the tailshaft.
put a mark at 12oclock on the axle flange and tailshaft flange.
a 3.54 should stop axle at approx 6 oclock posi, 3.77 would be approx 9 oclock and 4.11 1 oclock.
i cant remember but depending which part you turn you may have to double the reading?

i hope im explaining it right, cos this is how i checked the diff for my wagon when i got it.
was told it was a 3.45, but it had 3.23 tags. luckily it was a 3.45.

Hi All , thanks for the tips , I tried a few versions of the above and pretty sure its a 3.54 , if that's the case its worth the effort of dismantling for a better look

Cheers Guys
