i need to know the amount of teeth on the ring gear on a cherokee dana rear if posible

 

whats 2.55? are you refering to a 3.55 axle gear ratio?

 

yes the gear ratio i thought it was 3.73 and 2.55 gears

 

?

 

nope.

they're

3.07
3.55
3.73
4.10
4.56

3.07 is 5 speed
3.55 is auto, or 5 speed with tow package
3.73 is hard to find
4.10 is 4 cyl/5 speed
4.56 is 4 cyl/auto.

that's "general rule of thumb" and things could be ordered otherwise.

 

Why do you want to know only the ring gear? Are you trying to find out what you have? There are bettery and easier ways

 

null on 456 never offered

 

Is there a place to run the vin number and get the build specs, like axle ration etc?

 

well here is the prob i have a 96 cherokee country w tow package so it should be 3.73 gears but the cover has 11-28-87 stamped into it and if it makes a dif i have 10" drums

 

bull.

explain to me the '85 xj waggy 4 cyl/auto with 4.56's that I stripped.

 

no tags on rear cover remove the cover and turn it untill u see the numbers on ring gear you will see some thing like this just an example 9-33 that mean 9 teeth on ponion and 33 on ring gear divide the lower number into the bigger one thats your ratio

 

10" drums means that's not the stock rear end. I've never seen anything but 9" drums after around '92


and there's numbers stamped on the ring gear. take the larger divided by the smaller and you'll get your equation.


now...why do you want to know this about the ring gear?

 

x2

 

because i need to know what the ratio is so i can replace the rear with the right replacment so i dont explod the t case

 

remove the diff cover (this will require refilling, as it will drain when you remove it)

look on the side of the ring gear for the numbers etc. like these


look for the two numbers close to each other. they'll be something like 46 and 11 (just an example)

divide 46 by 11 (divide bigger by smaller) which would be (remember, this is theoretical numbers) 4.18 gears.

that is the only real way to tell.

and you haven't told us what rear end it is, d35 or d44. plus, there's different teeth per gear, so you actually need to know the ring and pinion numbers to get the proper answer.
