HP D44 owners

How much have youll spent on them? Im looking at a deal that will really help me out in my SAS project, and it involves one of these axles.

I haven't spent anything yet and had the axle given to me off a truck that was to be melted down for scrap but had a good engine and front axle. I took the axle, a mechanic took the engine, the rest of the truck is now part of a 10" thick, 80" wide steel slab that will eventually become a steel plate in a bridge or railcar or ship or tank or whatever.

What year and what vehicle is it from?

any of the ones that can be used for the EB and pickups. It for a friend so he can do rear steer on his truck, and i can get his rear axle. He wants that, and i want the axle because its already built, spool and 5.38s. So if i can get him a HP D44 then i can have the rear D44.

Okay. Keep in mind that they're not all alike. The 78/79 D44 HP's are a two piece axle tube design and don't work well with leaf springs.

They have an axle tube that goes from the center to a cast piece that the spring and radius arms hooks to. Then a short piece goes out to the end where the ball joint mounts.

Many of those axles have thinner axle tubes than the leaf spring versions because they don't have the spring directly connected to the tube. They're not as strong in leaf spring applications, but are great if you use coils at the original locations.

The one I have is a 79 F-150 and I'm mounting it with the original F-150 coil buckets, arms etc. -- basically reproducing the F-150's coil front suspension.

i think theres still a lil confusion. Hes wanting the HP D44 to run in the rear, so he can have a rear steer setup. Hes running one up front already with leaves.

Hes running a D44 in the rear, from the same waggy i got the front D44 from. I plan on basically trading the HP for the rear one since hes already built that one, and ill have the same bolt pattern all the way around, also will be able to run 5.38s.

I just read over on TRS that the ~78/79s had the c-wedges cast as one with the axle tubes. Unlike the earlier 70s ones that were welded on to the tubes. running leafs may not be to much of a concern, but hes talked about running a linked coilover rear.

what years are most people getting a EB D44 from, 78-?

He wants a front HP D44, and he wants to know how much he can get one for.

The D44 will be used on the rear of his buddies truck so his buddy can hook it up for rear-steering.

You can get one for cheap, but you will spend 500-750 at least replacing balljoints, bearings, seals, brakes, u-joints, etc, etc. Not to mention that you'll need gears, install kit, and a locker. If you decide to really beef it up and go with alloy shafts and HD ujoints like a CTM you can add another $600-$800 to it. It adds up quick, believe me.

I understood exactly what you were talking about -- I was just warning you about some of the coil spring ones. They're great axles, but marginal for leaves no matter WHAT end of the truck you use them on, lol.

to make a front Dana 44 run in the rear of a truck you will have to extend one side axle tube and axle and then shorten the other side tube and axle........you will not be able to just put it in because of the offset center section.........

just remember if you are putting in a Dana 44, the best ones to get are from full size F-150's then have them cut down to the width of a Ranger or leave them full width.......the early Bronco axles are low pinion and when installed in a lifted application will wear out u-joints in the driveshaft........the full size truck Dana 44 is a high pinion unit which means the pinion gear sits on the upper side of the center section which is more sutiable for lifting.....

Isn't it true that if you put a front HP Dana 44 in a rear position, it will turn in the wrong direction unless you ALSO flip it upside down? If so it'll no longer be high pinion.

that is also true....didn't think of that.....so if you are wanting to run a Dana 44 in the rear and have rear steer, the best axle would be a early Bronco Dana 44 because after you flip it, it would be a high pinion axle...........

if your friend has all this other stuff done, why not just get Rockwell axles.....

However, you have two issues if you do that.

1. Filling the axle -- might be you find the fill point is wrong when it's flipped.

2. Pinion lubrication -- you need to put a proper "oil flinger" on there to get the lube up to the pinion bearing properly.

Item 1 you could just make a new fill point I think if it's necessary.

Item 2 is really just a large metal disc between the pinion and the inner bearing that rotates and flings oil up. Not sure if any other design features of an HP housing need to be addressed. But if you just flip and don't pay attention to pinion bearing lube, you'll have problems for sure -- eventually anyway.

yes........i dont see the point of going to rear steer unless it is a hardcore competition rock crawler......even at that there are things to take into consideration....things like John stated above............

if your friend is dead set on doing rear steer, push him to get 2.5 ton Rockwells....that would be the best bet to do rear steer unless he goes to a company like Currie and has them build him an axle...

a rear dana 44 should be pretty close to the same offset as a 8.8 should it no? its got a center offset. only ting i would have to do is move the perches out to the width of my frame compared to the samuris.

so ur friend wants a high pinion dana 44 to run in the rear so he has rear steering? aint gunna work, the axle isnt made to rotate in the opposite direction and u just cant flip the axle to "work" in the correct direction.

someone correct me if im wrong. but ford d44s are reverse rotation, im guessin this is because of the way the tcase turns. if you get a chevy or dodge 44, you can use it for the rear.

it all says where the pinion is located. high pinion means the pinion gear is above the centerline of the axle. it also makes the gears turn in a reverse rotation, which is built into the gear set and axle itself. the reason for this is more tooth contact which is stronger and less prone to damage.

the t-case can spin in either direction, all it is is some gears and a chain with an input/output.

yes u said that, but no one really knows why it wont work

would a case work from a front TTB D44 in a HP D44 axle?

Im going to be getting the rear 44 from him, since it wont be much a problem to get it under mine.

As his sits now, the dana 44 rear thats under there, has a center offset, but his samuari driveline is offset to the passenger side, which when you put a front D44 back there, it would be passenger side.

u can weld a ttb dana 44, remove the center pivot points and weld it togethor with steel so it doesnt bend..wallah strait axle

but why not just use a regular D44..
