Put in netrual.turn propshaft 1 revalution and count home many times the wheel turns.
Am i missing something? whats a diff ratio got to do with a new Boots store opening, ie the boots ad in your post, or have I missed the plot?

jack up 1 wheel. (if you have a non posi diff.) Then mark the wheel with a line. Get under the car and mark the prop (or uj) with a line. While you turn the prop and count the revolutions, ask some else to shout when the wheel completes a full 360 degree turn.. Now you will have a good idea of the ratio. If it took you 1.5 turns to get the rear wheel to turn 1 rev you have to times the 1.5 by 2 to get your ratio.
Why. Well because you only had one wheel up from the ground it means that it will turn twice as fast as it would have done with 2 wheels off the ground.
So you turned the prop 1.5 revs to get the wheel to turn 1 rev. Take the 1.5 times 2 and there is your ratio. 3 to 1.
God I hope you can understand my babblings

I would say turn the prop 10 times as it would take some of the inaccuracy out of it if you're looking for a reliable and accurate number. As you're doing it by eye, laying under the car, are you really going to notice the difference between 1.5 and 1.6 turns (for example)? But the inaccuracy between 15.0 and 15.1 turns is less of a percentage even though the error is the same.
Might also be easier to get someone to turn the wheel rather than turn the prop.
Meep Meep.
My Intro
i think we should all host ads and deny all knowledge of how they got there....just to see your reaction
Thanks guys, fad15 spot on!
I was on my own so took stang's advice and got someone to help. Took it over to Hauser's and we did exactly as advised above.
Turns out the diff is shot, so it's now booked in with Geoff for a rebuild.
