[swany]

hey, didnt know if this goes here or in modified but here we go, i am trying to get some gears but dont know what rear end i have. the number plate on the front diff. is scratched to hell and the rear doesnt have one. my jeep is a 94 4 door 5 spd 4.0 with a 4.5 inch lift and 33" tires(35's next summer) could somebody tell me how to find out what rear and front i have and also what gears i should get to keep it a dd and have my power and torque back. thanks

front you have a dana 30 highpinion non-disco, for sure.
in the rear its not a definate, but up north ive seen much more chrysler 8.25s they have the flat lip on the botton and a rounded face, the other option would be the dana 35 no lip at the bottom and the face has like a half moon poking out of it.
the best indicator would be the flat lip at the bottom of the differential. and the tube will be thicker as well.


edit: damn you beat me too it.

An easy way to tell is if the rear has a rubber plug its an 8.25, metal plug is a D35.
