2000 Xj with 8.25 in rear and the front had no tags on gear oil has been changed so all the tags were gone contacted Jeep directly sent me back an email 8.25 rear 27.50 front 3.55 gear ratio. What is a 27.50 Dana 30 or 35? Looked on search no one has a 27.50 thread.

 

all cherokee's came stock with a dana 30 up front.
auto, probably 3.55

 

Thanks.

 

not sure what the 27.50 means.
the d30 has 27 spline axle shafts, but the .50 has me confused.
