I got a 91 Cherokee that had 3.07 gears and 235/75/15 to 3.55 gears and 31s. Is there a chart to figure out the what gear I need and also were to I get a new gear

 

heres a chart ebay can get ya a used one for alot cheaper there are long and short ones need to see which one you need....http://www.jeep4x4center.com/jeep-sp...ears/index.htm

 

Thanks that chart works perfect

 

any time

 

quick question here, it says on the link to change the pinion O-ring also when replacing the gears or youll leak tcase fluid, thus leading to my question where does this gear go? and how do you replace it? my jeeps speedometer has been off ever since i lifted my jeep and tossed bigger tires on, now that im installing new axles with 4.56 gears id like to be able to have the correct speedometer reading. any info on this would help as im currently 100% clueless on this subject

 

can ya see where it goes

 

Does it go where the hole is. I can't actually look on my xj im on vacation now

 

yep right in the hole it goes

 

thats what shes said

sorry i couldnt help myself
