8-3/4" axle ratio?

[moparnation74]

Stock Gears have the ratio's stamped on them....lol

And if they aren't stamped or you can't find it just count the teeth on the ring and on the pinion and divide.

Did you not just post that earlier? Post #16...Or did you forget?

 

[PP1RT]

The earlier post i said to look for the ratio stamoed on the ring gear. The later post i commented that he can also just count the teeth.

I can see you are hurt by my disagreeing with your idea of turning the wheel 2 times and counting how many times the yoke turns. I guess i will step back and let your expertise in this subject take over now.

Really, dude...whatever makes you feel better....OMG I turned it one more time than you, lol yielding the same result....
Expert? Me...lol not by a longshot...thats what we have you here for

No you dont achieve the same result unless you divide the yoke revolutions by two. If you would have said that i would not have disagreed with you. Why you would want to make it more complicated than it has to be is beyond me. There are others reading here that want to learn things the right way. Explain it completely next time to avoid confusion to those that are trying to learn.
I disagreed because your info as posted was incorrect/incomplete and could confuse those new to the hobby.
And dont call me "Dude"

Yup, stock gears are stamped with the ratio but it's a lot easier to just make both axles turn the same (non SG) as if were in the car if wheels are available.....and you don't even need tires on them. Yeah, it's not that big of a deal to remove the chunk but imo, it's more work. I've checked plenty of ratios on trucks just by laying under it and rolling it making sure everything was safe. Cars are harder since they are lower plus I'm not nearly as skinny anymore. Also, Stock ratios are 2.76, 2.94, 3.23 etc....not that it matters much between a 2.73 and a 2.76 lol. And why can't we just all get along!?

People can do simple math...hence 2,#2 revolutions, lol...some people like round numbers obviously that disrupted your day, weird indeed...

I guess the people that agreed with my post understood as well...but one person did not....lol

 

[eldubb440]

if both wheels don't spin the same direction, it simply doesn't matter.......

and me disagreeing with you caused hurt feelings. Don't worry i am sure you will get a participation ribbon. Maybe we can start referring to 2.76:1 gears as 5.52:2 gears


i removed the disagree mark from your post. You are right. It is accurate and informative. Good job!

Now that was a long post. May I make a suggestion here, as it has worked for me since The Military used black powder.

1) If the car is a Suregrip: with both wheels off the ground I rotate one wheel exactly 360 degrees. I watch the yoke, and it rotates 3 1/4 times if it is a 3:23 ratio.

2) if the car is NOT a Suregrip, I do the same thing. But, every single time I do that, the yoke rotates exactly half of the number of times as a Suregrip. I would get a hair more than 1 1/2 turns of rotation of the yoke if an open 3:23. The principal is the same if the assy was a 4:10, 4:56. whatever. The non Suregrip yoke would rotate 1/2 as many times.. simple. Works for me!

 

[moparnation74]

and you disagreeing with ME caused ME hurt feelings. Don't worry i am sure I will calm down and realize my mistake. Maybe we can have a group hug and call it a day!

Fixed, lol

 

[monaco66coupe]

Fixed, lol

and how do you get popcorn? I can't figure out where that comes from! DUH!

 

[PP1RT]

So in your first post you have one wheel on the ground but in the last post you have them both off the ground turning the wheel 2 revolutions and coming up with the same results. Am i reading this wrong?

Oh yea, my wife finally noticed I'm Talking about cars on this site Instead of watching the Movie! I said: Make some damn Popcorn and I will! HAHA

I am in the same boat, too funny my friend...I got the stare as well due to my snickering

Moparnation's explanation makes the most sense. With an open rear, and one wheel fixed on the ground, the free turning wheel will turn at twice the speed compared to a sure-grip with both wheels turning. That's how the pinions work. So a 4.10 ratio will have the driveshaft turn 4.10 times for one tire rotation if sure-grip, but only 2.05 times with one open ended wheel in the air.

That is the danger of spinning your tires on wet roads with an open rear. You're barely moving, and the speedo says 65 mph, but that single tire is actually spinning at 130 mph. while the other one sits still.

Yup, non Suregrip yoke will spin at 1/2 half the total as the Suregrip. Predictable as the day is long!

Yep you are correct on an open diff x2. Sure grip you would count once. Open-one wheel blocked sure grip- both turn. You would not turn the sure grip 2 revolutions of the wheel. That is what i am trying to say but reading back thru i can see that doesnt come thru clearly. So we are saying the same thing but turning different things?

your good, you got it figured out. Now in the future it will be a breeze/ Mopars are easy, uniform in design, and very predictable.
