How to determine gear ratio in Ford 9"
I thought this might be a "greenie" question, but I need to know anyway. How can I figure out the rear end gear ratio in my truck that has a 9" Ford?
I think it has an LSD of some sort, but I haven't checked that yet. I'm just guessing because whenever I goose it, I feel both sides engage. Yesterday I goosed it out of a corner, and it spun straight, did a little "S" then moved out real nice (everyone in the cab just kinda got momentarily pasted to the rear window).
I don't do this often (yeah right!), but anytime I do I get a good response from the rear end. My miliage is also pretty good on the open road anyhow. In the city I get about 13MPG and I have 225R 70 15's. Help in figuring out the ratio would be appreciated. THX...K
