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!

[jeepsr4ever]

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 :oops: . 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!

[Trusty258]

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

F150 or brnco is my guess

Jesse

[78304CJ-7]

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..... :roll:

[78304CJ-7]

Yeah for sure thanks again. What is involved in getting a Dana 60 with 5 on 5 1/2. Just new axles? Who is good for these BTW? I am sorry but 3 grand for a axle just ain't happening, Currie can you know what. :twisted: . So the search beings. Are the oder jeeps good doners. I am thinking I might go back to that 70 J series truck that I pulled my tranny from and seing if that has a 60 on it. I am sure it prob has a 44 up front. What did most of them come with for gear ratios?

-RJ

[jeepsr4ever]

their is one style dana 60 that came in old fords, IH and jeep full size trucks 67-73 called the 60-2, they had 5 on 5.5 bolt pattern and were semi floaters, I would run a full width 8 lugger though. For many reasons including the more lugs you have the bigger the tire you can run, ask anyone who ran the 44-18/15's on their jeep! They will tell you that you need a thick steel rim or your studs and lug nuts come loose and wear

[78304CJ-7]

I agree, I would like to run 8 lugs but I don't want to have to get new rims at the same time all around. This is gonna cost me enough as it is. besided this jeep will never see 44's. So that is why I would like to keep it 5 on 5 1/2. I guess I will have to start diggin'

-RJ

[jeepsr4ever]

LOL never say never.....oops i said it twice :oops: You could always run a d60 8 botl with wheel adaptors! I is costly though, i make them ..4 from 8lug to 5lug run around $350...I dunno might be worth rims :wink:

[78304CJ-7]

Guy on the FSJ board has a dana 70 rear and 60 front from some Dodge truck. 500 bucks for the pair. The rear I guess is set up for Dually but can be fixed. Sounds like a good deal. Hoe much bigger is the 70 rear then the 60? Am I going to be draggin' the ground with 31's?

Edit:

I posted pics on my website below, go to it and click axles for images, click on images for larger pics.

[jeepsr4ever]

you may need to run a 16" rim making those 31's obsolete, but a dana 60 front and 70 rear for under 1200 is a steal,,,,go for it man!!!! yup something to be said about doing it right the first time!!

[BLHTAZ]

I have a Ford 8.8 out of a Towncar with brand new 3.08 Ford gears if you might be at all interested in that. It is on eBay right now and can be seen here:
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2436162094&ssPageName=ADME:B:LC:MT:1

It is 5 on 4.5, but you could change that.

[78304CJ-7]

MC did you check the pics out. Does averyhing look ok? They measure up like this: The Front perches are about 32 1/2" and the rears are about 43 1/4. How does this sound?

Will this work ok?

Now what are your thoughts on SOA on Cj's are these the way to go?

Um the only thing is they have wimmpy bearings compared to the truck axles. Thanks though.

[jeepsr4ever]

SOA or poor mans lift is a lift you dont want on the street, 36"s is the frame width in the rear for cj's 75-86 and the front was 29" (?).....? i thought thats what it was, anyways i would outboard the springs on the front and move the purches on the rear axle for the cj width.....get em buy em' ......or tell me where to get them..........LOL :o

[BLHTAZ]

SOA or poor mans lift is a lift you dont want on the street,

Why would you say that :?: :?: :?

SOA is a great thing to do for all around lift, ride and flex. I definately would not call it a poor mans lift...they can be more expensive than most lift kits when done right.

[jeepsr4ever]

The ride on the street is dangerous for SOA on a cj, with stock axles. I did jump the gun dangit TAZ you got me man!!!! I run soa and i think it is the better of the two for flex and even for jumping your jeep, but would i tell someone to go soa?....probly not...because if it isnt done right you can kill yourself ..not that i am a conspirator but man we just got to make sure everything on your/my rigs are rigid/well built or accidents can occur, thats how i lost a good friend of mine so maybe i am a little gun shy about telling some one to go SOA

[78304CJ-7]

From those whom I have talked to I HAVE to go SOA with these axles if I am going to narrow them. (Dana 60 front Dana 70 rear). It is because of where the pumpkin is located on the dana 60 (so close to the knuckle). I guess another option is this. I think this is what you are refering to.


http://poisonspidercustoms.com/Axles/axlekits.htm


But I don't think I could get my car inspected with axles that wide on them. Maybe maybe not. It look cool for a trail only rig but I think it is kinda strange looking when I see one on the road with it.


Do you run a ladder bar to deal with axle wrap on your SOA? Also who make a good Disk break conversion for the dana 70 rear?


-RJ

[jeepsr4ever]

yeah you would have to go spring over, but the good news is that with your bigger backing plate you will gain some stability, you dont need ladder bars unless you have major wheel hop or axel wrap, which you may get from the increased weight and gear reduction, its a hit and miss with the spring type though, remember when going to larger brakes or disk rear the MC must be changed to one with more volume, it is not as easy as just swapping for disks

exactly my thoughts, any good ideas for a Master Cylinder swap canidate? Wondering what my options are. Also many have said I should upgrade th yoke on the back of the D20? Think so?

[jeepsr4ever]

early 70's corvette MC will fit..........MC, i would upgrade the yoke and run a cv shaft

[CJ Shark]

The Vette MC is good when you run 4 wheel disks as well. The primary & secoandarys are equal size so you can probably get by without the prop valve.

I had the vette MC and it worked ok, but I switched to a 70's Chev 1 ton mc. It has the same design (primary & secondary of equal size) But it moves allot more volume thus giving more stopping power.

I'll try and look up the part number for it.


But either one of those will work fine. I believe the Vette is the 1968 1 1/8 bore 4 wheel disk MC. Make sure its the 1 1/8 bore.

[jeepsr4ever]

good info CJ!! :wink:

Sounds good. Let me know part numbers if you can. How is the mounting compared to the CJ. I just dropped a new Perpotioning valve in with new lines so just rather keep it there.

Thanks CJ

[CJ Shark]

I'll try and find the part number for the chev tonight, at work right now.


The 2 are almost exactly the same bolt patern as the stock MC, so they will bolt right in.

The only problem you will encounter, but with your prop valve this won't be a problem is;

The Vette MC (and I think the Chev is the same) the brake lines are reversed. The (i think 9/16) line on the jeep mc for the rear brakes will now bolt onto the front (primary) side of the new mc.

With the MC bult for 4 wheel disks it shouldn't matter, but keeping your prop vlave is a good idea especially when the lines are being reversed.


Oh and forgot the best part. Even though you would think otherwise, especially when its a '68 vette part.............the MC is bloody cheap. You can probably get a new one (not rebuilt) for less than 60.00 of your yankee money. :D

(cost me about 100.00 canadian :roll: )

[jeepsr4ever]

LOL yakee money..........hey cj check out geminisales.com they got lots of jeeps parts up der in canada dont you know.......LOL Hey man awesome first posts.....

[78304CJ-7]

How does this one look:


http://www.partsamerica.com/PartDetails.asp?SourceArea=&SourcePage=SEARCHRESULTS&MfrCode=BEN&MfrPartNumber=11331&PartType=230&PTSet=A

Specs:

1970 CHEVROLET C30 PICKUP V8 6.6 Liter

New; 1 1/8"; w/13 x 2-1/2 Rear Brakes $59.28

Right on the money 60 bucks.

Will me PB diaphram fit on that ok?

I doubt this was made for 4 wheel disks though. A 68 vett has rear disk brakes?

[CJ Shark]

http://www.partsamerica.com/product_images/AAP/BEN/10/101534.jpg

It looks more like this one off a 78 gmc 1 ton. You can see how the primary and secondarys are the same size, and the size of the reservour that gets pushed to the brakes under.

The vette looks almost exactly the same, just not as beefy underneith

http://wheelingpiazzas.com/pictures/brakes/DCP00552.JPG


You can kinda see what I mean off these two pics. And yes the vette came with 4 wheel disks even back in the 60's.


LOL thanks Mr Moderator guy, I try to help :D


Edit......this picture of the motor is not mine. No way I'd let mine ever get that dirty :lol:

[78304CJ-7]

No power breaks on your bad boy? Do they make a power break version of that MC?



What is that smog stuff doing on that engine.... ewwwwww :mrgreen:

...... Just kiddin'

Thanks again!

[78304CJ-7]

I see that one it is a 1 1/4 inch though here:

http://www.partsamerica.com/PartDetails.asp?SourceArea=&SourcePage=SEARCHRESULTS&MfrCode=BEN&MfrPartNumber=R11730&PartType=230&PTSet=A

There is also a 1 1/8 inch on here:

I looked up the one for the 68 Vett and got the same part number as above so this should be othe one correct?

60 60 60 is all i can say! :lo1l: Even though the 9 inch is good and strong { we have used one in a 2200 hp small block car } i put a 60 in my cj7 as havent looked back ! If your concern is the lug pattern cut off the ends and install ford big bearing ends and get axles from some one like moser as i did! You can then use the big bronco drum brakes. 60s hang down a little lower then the 9 inch but you wont have such an extreme drive shaft angle !60 60 60
