Did ford ever produce front HP axles other than dana 60's? not 44's I mean Dana 61's or 62's. I found a couple of them and the guy doesn't think they are 60's but I'm pretty sure they are, there is a number cast into them about 8 digits long, 602??? or something like that. are these 60's?

what is the whole 6 digit number?

I don't know I'll go back there @ lunch and write it down

Is the number cast into the pumpkin or stamped into the tube? A 6 digit number starting w/a 6 sounds like a Dana BOM number.

Pete

Its cast into the housing it looks like it says 6200893R and the other one says 47721 but its ball joint and the other is similar to the first 6200888 maybe I'll try to post a pic

here is one of the ball jointed one not so big

The one with the kingpins sure looks like my hp 60 to me. The ball
jointed one looks like a dana 50 from a newer f250/350 single wheel.

get the 6 digit number off the tag on the diff cover. the 7 digit number you gave doesn't compute. 6 digits *stamped* NOT cast into the axle tube and the diff tag. starts with a 6 has 2 to 4 digits after the 6 initial numbers you need.

After you get the numbers you can look them up on http://www.patooyee.com/ under dana BOM listing.

For anything larger than a 1/2 ton Dana only made the Model 248 Reverse Spiral Gear Set in the 70's and 80's. Not sure about 90 and up.

(That's a Dana 60 for those of you who don't use Dana's Expert web site)

trying to sound smart while lookin dumb!:flipoff2:

The ball joint one is from a 1999-newer F350 front end. I just put one on my '95 wrangler. I'm not sure what the difference is between d50 and d60 but mine had full 1.55"(no taper) inners which I had shortened by Dutchman. Outer is 30 spline though. It took 5.13:1 gears for a d60 along with the carrier so I figure it must be a d60. So far I like it, but I'd still prefer King-pin.

I agree with Rockhog.

The only way you can tell the 99-newer D50 from the D60 for sure is: the 30 spline shafts, D44 size R&P (the diff covers are the same size), and the rear snout on the D50 is a little shorter than the D60.

The king pin axle is a 60 from an '86-92 Ford F350. ~36" spring perch dimension. They aren't as friendly for off roading as the 771/2-'79 Ford 60's. The springs are too close to the king pin which causes the tires to rub the springs more easily than the earlier axles.

Hey fellas I am looking at swapping a d60 front into my 80 Bronco..
So the 77-79 d60 is the one I want to keep an eye out for ehh?
That year has ball joints, not king pins?

late 70's D60 have king pins.

Mid 77 to ~'92 are king pin. After that are ball joint.

If you are looking for a 60 for a coil spring conversion you will need the 77 1/2 - 79 axle. It's not very easy to do on the '86 and newer Ford axles because of the short distance between the spring perch and the inner knuckle and the wide spacing between the spring perches.

Thanks for the info.......
So is the ball joint design preferred over the king pin version?

Guess it depends on who you ask. King pins are good for hi steer setup. Supposedly the king pins are stronger but its just what I heard. The 78-79 60's are preferrable because of the larger amount of space bewteen the knuckle and the diff. In the picture above with the king pin 60 you can see the clearnace for coils is very tight. The 78-79 60's will have more room.

Interesting discussion. The front 60 I'm building is from an 85 F350. I plan on shortening the long side 3 inches, for a WMS to WMS of 66 inches.

And I'd planned to run standard Hummer beads with this setup. Am I going to run into problems with the tire hitting the springs on the driver's side? BTW, this is a SOA YJ.

Not sure on the Jeeps. Personally I wouldnt take the time to cut it just 3". Either cut it more and run regular wheels or dont cut it at all and use the hummers. Before I would do anything I would stick it under the jeep and made sure everything clears before I start cutting. I am not much of jeep person so maybe others can help you out better than i can. Good Luck.

Blatant:

'85 came with IFS on the F350. '86 was the year Ford came back with the solid front.

You will need to cut ~6" off if you are going to run the stock width leaf springs on a YJ to get the correct spring center line. You may get by with 5.5". It's been 5 years since I did mine so my memory is a little fuzzy. The reason you need to take out that much is the diff side perch can't be repositioned very much. Maybe 1/4 - 1/2" by ovalling the center hole in the spring perch.

I'm running 39.5 boggers and yes they rub the springs with 16.5x12" wheels with 3 1/2" backspacing. I've cranked the steering stops out and now they just touch the edge of the spring.

If you are going to run stock hummer rims you will need to either use a '771/2-'79 and leave it full width or narrow the '86 and later and run dually hubs in front. If you try using the '86 with hummer rims you will definitely rub big time.

As I said before I narrowed mine ~6" and am running dually hubs up front with stock hummer rims. I haven't checked the clearance since I changed it but it doesn't rub right now. I'm guessing it will when I finally get some time to play.

Hmmm. I ran the BOM number off the axle housing and came up with 1985 F350.

Regardless, by my calculations, three inches off the long side should be enough. We're going to flatten and fill in the cast section of the driver's side as much as possible to create a new spring pad. From there, measuring 31 inches (center pin width on YJ) to the other side would leave me with three inches to cut off.

So, no way to run stock hummer wheels on this setup without tire-into-spring problems? My proposed tires will either be 38.5x14.5 SX or 39.5x15 TSL. I was trying to avoid having to redo the brakes, as the Ford brakes are in good shape.

Going off memory again. 36.5" spring perch dimension on the '86 and newer housing, -3" will give you a 33.5" perch to perch dimension. You will need to move the short side mount and the long side in 1.25" to align with your springs.

You will have to carve into the housing quite a bit to do it. It's not impossible just a lot of work. That will give you an extra 1.25" of space between your wheel and the leaf spring. The hummer rims are 7" backspacing and I was running say 3.5" backspacing. That still leaves the hummer wheel 2.25" closer. I'm pretty confident you will have major rubbing or minimal turn radius.

By the way, you will not be able to use a U bolt on the inside of the short side perch if you want to remove your diff cover. You will have to fabricate a bolt or stud configuration like the Chevy or Dodge 60's.
