Ford 9" or Dana 60

[78304CJ-7]

Ok. Well I was looking in the paper today and saw an add that a guy was selling a rear ford 9" with 3.00 posi in it with disk breaks. he wanted 250.00 is this a good deal? I am thinking I will have to replace my AMC 20 in the back of my CJ when the new 401 gets dropped in. I know I would have to swap the gears in it. Would a 3.70 or 3.75 be close enough to my stock 3.73 I have in the front. I have no idea what it came from. He has 3 Caddy 500 ci engines if anyone is intrested I can buy them and crate them.

I have also been considering a Dana 60 in the rear. Which is better. The one thing I like about the 9" is it is already 5 on 5 1/2. So I can use my wheels that I already have. I know the Dana 60 is a FF and the Ford is a semi float. Do I really need a FF my CJ isn't that heave!

Normally i would say 60, but that 9 is a decent deal, i would take it...heck the disk brakes are worth it, but make sure its not a light duty housing and small bearing like one from a grenada!! they arent really worht the effort, if it had stock disk brakes pass on it!

[78304CJ-7]

ummmm.... pardon my axle ignorance . How do I tell if it is light duty. Also I guess I can ask the guy if it had stock disks but how can I tell? What the heck would Ford have used a 9" with stock disks on?

[jeepsr4ever]

70's and 80's ford sedans, it is a light duty housing if it has only one crease on the tube, the heavy housing have an extra thick housing if i had the pics i could show you, really easy to tell, or maybe you could post a pic

[78304CJ-7]

I haven't seen it yet. Still gotta call on it. What should I ask the guy when I talk with him tonight?

Does the crease run along the tube horizontally along the top, if it has two creases will they be 180 degress from eachother?

[jeepsr4ever]

no it runs vertical like an extra wrapping of sheet metal, but it only goes a quarter way down the tube, ask him if its from a car, if it is offer him $100 for it, thats all it is worth. If he doesnt know ask him if he did the disk brake swap, if he didnt it is probly the crappy small bearing ford 9" light duty

[78304CJ-7]

Sounds good. I will call him tonight and see what he has done. He had a pile of stuff for sale some tranny's and all. So I asume he knows what he has got. Let you know then!

i cant imagine a 5 on 5.5 axle coming from a car, they were 5x4.5 right?

F150 or brnco is my guess

Nope came from a sadan with stock breaks. I figured such, coming with 3.00 gearing. Told him it was light duty, he huffed and puffed and said it was standard 9'. I told him all the sedans where light duty with wimpy bearings. He at least agreed to that! Lol. Nothing like an educted buyer! Gotta love it. Thanks MC. Well I guess back to my original question....


Dana 60 or Ford 9"?


Pros cons of each?

[jeepsr4ever]

60 brother and i got many of those, otherwise you can get them for cheap at your local boneyard. I also have dana 44 scout axles, glad it worked out though, would be a bummer to me if you had boughten that axle, he will never get what hes asking for it, unless he tricks someone into buying it.....
