Ford 9 Inch and HP dana 44

Hi,

I recently stumbled upon an add for a 9 inch and HP dana 44 for 250$

"ford 9 inch (31 spline) and HP dana 44 out of a 78 ford f-150, the dana 44 is complete down to the links. the ford nine inch has had all the brackets cut off and jeep tj coil buckets tacked on. "

I'm currently only on 2.5" of lift with 31" tires but plan to go 33-35" in time.

I've been searching craigslist for axles for a few months just trying to find a deal, or really anything... I live in Vancouver, BC. so finding a 44 is very rare, and 8.8 just as bad.

Anyway I'm mainly just wondering if this is a decent deal? and I'm assuming that since the 9inch already has the buckets tacked on there really isnt too much work involved in making that a strait bolt on swap? Also if i would need a SYE for the swap? Or really any other information...

Thanks, Landon


(And yes I have searched the 9inch on the forum a little bit, and have been getting mixed results in terms of the questions I had)

Edit: Due to having a d35/d30 setup now with 3.07 gears, I would have to re gear anyways for the 33"

Unless you plan on running Ford radius arms you should make sure that the HP44 doesn't have the cast wedges. I don't believe that it will but double check. Other than that all new brackets will need to be welded on to the housing.

As for the 9 inch It will need more than coil buckets in order to be bolt in. It still need control arm, shock, swaybar, and track bar brackets welded on. Since the pinion is lower and longer than your current dana 35 you will more likely than not need a SYE.

With both axles width may be an issue. They will be wider than your current axles and will require rims with less backspacing. Then again new rims will be needed due to a different bolt pattern.

It sounds like a decent deal for just the housings though. Keep in mind that the axles will likely need to be entirely rebuilt and parts add up quickly. Pirate 4x4 has some more information and build ups with axle swaps and would be another good resource to learn about the work involved in swapping axles.

78 Ford Dana 44's have the cast wedges. 78 was the first year for them in the F150/Bronco.

I think it's tnt customs that makes a nice truss system for that axle. It would allow you to use that axle with tj bracketry. And yes that's a decent price for that set of axles.

The truss you are referring to is for the HP Dana 44 with WELD ON wedges ONLY. It is not compatible with the Hollow Cast wedges like will be found on this axle.

This 78 Dana 44 is basically worthless for a swap.

use the ford arms for a long arm, re-tube the axle, or find a 78-79 f250 hp44, or 1976-1977 150 axle.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.

Using the Ford radius arms is probably the best option for that front axle, but it's a half-assed fix if you ask me. Re-tubing it is going to cost more than a HP44 is worth, if you do it right.

Getting a HP44 from a '78-'79 F250 or '72-'76 F100/150, or '78-'79 F150 crew cab is your best options for a HP44. '72-'75 came with drum brake style knuckles, but thats not an issue if you plan on switching to Chevy flat tops, or disc brake style Ford knuckles are easy to come by. I would try to shy away from the '77's, from '72 to mid year '77 the F100/150 HP44 came with 2 3/4"x1/2" wall axle tubes, after that they changed to 3/8" wall.

'78/'79 F250 and F150 Crew Cabs were very close to the same axle, both used the 3"x1/2" wall axle tubes and leaf springs, but the F250 used 8 lug knuckles and the F150 Crew Cab used the 5-5.5" knuckles that the rest of the 1/2 ton trucks used.

All very true. The ford axle is also 6 or 7 inches wider then the tj axle as well. You will likely be much better off going with an exploder 8.8 rear and a hp30. If you can't live without the bigger axles then build a 9" rear and a hybrid 9" front or better known as a 69 . This is stronger then a d44 and has better ground clearance. But it will cost much more then $250.00

Thanks for all the reply's saved me from buying the useless hp44. talked to the guy a bit, and did a little more research and looks like ill be picking up the 9" for $100 and the width shouldn't be that big of a deal, will just get rims with the right backspacing?

Also I'm not planning to do the swap for quite a few more months so there's still plenty of time to find a front axle
