A Quick Easy Way To Determine Axle Ratio
Paul Cangialosi came to my shop to help me do the rebuild on the T5 transmission that’s going into my 1979 Ford Fairmont. We were at the point of trying to figure out what speedometer gear to use when he asked what the gear ratio of the rear end I was going to use was. I said I didn’t know and he said he had a quick way of figuring out what I had.
This will only work on differentials with posi traction. That means that both wheels spin in the same direction when the pinion flange is rotated. If one wheel rotates one way and the opposite wheel the other, this method will not work. If however you have a posi traction rear end like I do, you’re good to go.
I can’t thank Paul Cangialosi enough for his time in the shop that day. I learned a great deal and hope to pass along that knowledge to you.
