Re: explain me this

Neal,

I doubt the sure grip story also

I'm afraid you've an open diff

And in my opinion with an open diff you have to multiply the rotation by 2.

So in that case you have a 2.92 or so highway gear.

OK, maybe I am descending into early senility or something. So yesterday i had the car up on jack stands, so i decided its a good time to find out what that rear axle ratio really is. The guy I bought the car from didn't know, but told me he knew it was a sure grip.

I get under there and put a piece of masking tape on tire, and revolve it till it lines up with front part of leaf spring. I notice right away the other wheel isn't turning so I question the whole sure grip thing ( not the first time I've heard that one). But anyway I the have transmission in nuetral and mark the driveline, and turn it by hand. It takes less than 1.5 revolutions of the driveline to bring that tape on tire around one full revolution. I can't believe it. I check it 5 times. then I do it the other way, I revolve the tire and count the driveline, same thing. What gives?? I have a 1.45 axle ratio?? Something I must be overlooking.

PS- car has 8.75 axle
