Why not take a picture of the cover and post it?

for the gearing, if there's no tag on the diff cover stretched between 2 bolts that tell you the gearing, then you'll have to remove the cover and look on the edge of the ring gear for the number. in that group of numbers will be the amount of teeth on the pinion and the amount of teeth on the ring gear.
something like 11-39 or something like that.

you would then take the 39 and divide it by 11 to get 3.54

btw, you probably have 3.55 if it's an auto.

 

i was going to but didnt have a phone earlier i will tomorrow. im sure doing that will help.

 

alright perfect i will try that tomorrow also and let you know how it goes thanks again. and it is auto but it has been opened before and the cover looks like it might not be original only reason i think that it might have upgraded gearing. and has crazy acceleration compared to my friends cherokee which also gets me to think that. it wants to peel out straight off the whole everytime

 

Here's the pic of it let me know thanks.

 

Looks like a Dana 35 to me!

 

i do have an auto and i did exactly what you said and the numbers are 8-36 which gives me 4.5 is that right has anyone heard of 4.50 gears i dont know much about gears. i can tell it has been opened before also because all the bearing have been changed and the company that did it marked everything iside with a k. these gears being 4.50 seem to be perfect for my use right

 

Anyone? I know I asked a lot already but this will be the last thing for this topic.

 

it is possible you have 4.56 gears.

i had it wrong, the ring gear number is stamped first, so the larger number then the smaller pinion gear number.
