identify a rear end!??!
Someone here on the forum is selling an entire rear end. However, other than knowing mileage and type of transmission (A4) he does not know what the gearing is (ring & pinion).
Is there a way to identify the gearset WITHOUT opening up the inspection cover? Stamping somewhere - perhaps the yoke? :rolleyes:

Find out what year, and what car it is out of, an dif it has ever been replaced.
Then ask him to write down the options list from the rear compartment , and you can find out the gearing from there..

Sorry - I should have been a bit clearer - he does NOT know or have access to the car the rear-end came from - don't know why or even sure how he got it!
That makes things abit tougher. :crazy:

The old fashion way can get you close if it does not have a tag on it. Make a mark on the drive line yoke to the case, then make a line on one of the half shaft yokes to the case. Turn the drive line yoke and count the number of revolutions that the half shaft yoke makes compared to how many times you turn the drive line yoke. For instance, if it has a 3.07 you should have to turn the drive line yoke a little over 3 turns to one turn of the half shaft yoke.

I believe the ratio should be stamped on the top of the casing, although this assumes that the ring and pinion hasn't been changed.
That is exactly correct. The ratio is stamped right above the date. This like TA says is assuming it's the original R&P.

Not all of the rears are stenciled like that. I think that started around 92 or so. It is not hard to pull the cover and look. That is the only real way to tell what R&P is in the car.

Ok than it was 88. I could not remeber if it was 88 or 92. However that does not change the fact that he really needs to look at the R&P to see. I know there are allot of 3.07's out there that are not 3.07's anymore.

Re: identify a rear end!??! (linkschamp)
WHy not just count the teeth on both the ring and pinion gears and divide the number of teeth on the ring by the number of teeth on the pinion? Since you already have the differential out and can look at it.
