    How do I find out what axle (Dana) I have in my 95 yj? If it's a Dana 30, AMC DANA 35, Dana 35 or a Dana 44 I want to change my gear ratio from a 3.07 to a 4.10 lockers. Any help would be helpful. My yj has 33s tires, I want 35s.


    Is it stamped on the axle and where do I find it if it is?

    Most accurate method Ive found, is to jack it up, and count the rotations of the shaft when the rear tire is spun one revolution

    1979 Jeep CJ7, 258, TH350, NP208
    Howell fuel injection, header, HEI distributor, TH350, NP208, SOA lift with YJ springs in the front & GW springs in the Rear. AMC20 with G2 1 piece chromos trussed, Dana 30 with G2 chromos and 760x ujoints and MM Stainless Hubs, Geared 4.56. Tom Woods shafts, Metal cloaks, Caged, 37" Toyo MTs.
    The picture graph below is how I figure out what is in a vehicle. It is also good to have if someone is trying to sell you a Dana 44 as a Dana 60 (likely cause they don't know either). The 60 has a noticeable ridge on the pumpkin.

    Your Jeep should have come with a Dana 30 front, Dana 35 back. In 94/95 the most common ratio was 3.07, but some towing applications from '87-'95 came with 3.73/4.10. If you plan on staying with the dana 30/35 combo I bet you could find a set of 4.10s off another jeep for around $300-400. This would save you time and money, and you could sell yours. If you are going to all that trouble, I would look for an older ford explorer and yank the 8.8 out of the back. It is a much better/stronger axle than the Dana 35.
