Anybody...on a '94 Grand Cherokee, 5.2 liter, 4X4, how do you tell what
the ratio is for differential replacement? I have a Hollenders book but the
numbers I found on the front differential cover bear no resemblence to those
in the Hollander book. thanks!

Usually there are two numbers on the tag... number of ring gear and pinion
teeth. Divide the big number by the little one. Example:
43 / 14 = 3.07

Forgot to mention... the numbers are usually on a tag under one of the cover
bolts.. not on the housing itself.

Jack up one back tire and then tape a peice of string to your rear
driveshaft. rotate the tire once, and then see how many times the string
has wrapped around the driveshaft. Not precise but you could modify this
method to be more accurate.
