I've been trying to figure out why D-50's are so bad. Did a search and from what I can tell, the only diference from a 60 is a little bit smaller carrier and ring gear and 30 spline axles. The carrier is bigger than a 44 and the axle joints are the same as a 60. I've seen a lot of 44 axles broken at the joint and not many broken at the splines so wouldn't this be a decent upgrade from a 44 or is there something I'm missing? Are they not any less expensive or more available than a 60, or is there a weak link other than the spline count that I haven't heard about? I've heard about gears as low as 4.56 and ARB makes an air locker for them. The ones I've seen have ball joints instead of king pins, but I thought the late model 60's did too. Seems like they would be more popular than they are. Can anyone clear this up for me?

The biggest reason most people dont use them are the weeny 30 spline axles, why go to all the hassle of a swap if ya don't gain much strength over a 44...but I doubt there all that common either, sence they are only used in 99 and newer non-dually superdutys

I thought they were more widely used than that. ARB's aplication chart says '80-on. I know how inaccurate aplication charts can be though. I didn't think they were that old. I thought maybe early '90s or so. Thats what I get for thinkin'! <IMG SRC="smilies/wink.gif" border="0">

I have had my 2000 S/D D50F rebuilt by ford under warrantee 3 times. It still makes funnynoises. Biggest problems I have found out about investigating my problems is
1) The vaccum hubs are prone to failure
2) The Axles Neck down at the carrier to 30 spline(But the shafts to that point are 1.5" with large U-joints)
3) Upgradable gear selection. I have found that 4.56 is about the lowest you can go right now.

But you point out some good arguemnets about their benifits. The housing is close to the same physical size as a D60F with the same ground clearance. And currently, they cost the same as a D60F. Maybe in the future, when they are readily available in wrecking yards, they might gain popularity.

I personally was dissappointed when I first saw that the SuperDuty's big front axle wasn't a D60F. I liked the Reverse cut and the large size, but the gear choices held me back.
I would love to dump my D50F in favor of a D60F of equal fit, if it were financially possible.

if you find one in a wrecking yard for cheap buy it. you could then build a for9" hybrid and have the necked down section removed and resplined to 35 spline or new inner shafts made if it would endup being too narrow . or maybe a rear d60 pumpkin added to it. you would have to figure out how to buld a spring perch but it would be doable.

I think this is where they are going to have the most benifit, this way you get strength and ground clearance. They need to make a "super 50" kit with bigger locker and 35 spline inner shafts

The way they are now you end up with the clearence of a 60 with the strength of a 44. Like the last post noted if they bring out a 35 spline option and lower gears I would bet people would be all over them.

Another lame thing about the 50 and the newest 60's is the unit bearing hub. If you go through water it is very nice to have bearings you can replace for $75 instead of $600

Very true. I would like to think they are better at keeping the water out but I doubt they are <IMG SRC="smilies/frown.gif" border="0">

i just bought a dana 50 last monday thinking it was a 60. i only paid $100 for it so im not going to bitch but i hear it will cost me $1,200 to $1,500 to get lockouts put on, i have no problem running pucks in the front. so does any company make pucks for it? and will it hold up to my stock 460 with a liberal foot and 38's?

superduties only came with the dana 50 from 99-01.5ish. 02 and up were all true balljoint 60s.

the unit bearings and vacuum disconnects are garbage. dynatrac makes the freespin kit for both the unit bearing'ed dodge and ford 60s, but it is $$$. It does however give you true spindles, hubs, and good old plain jane timken wheelbearings. don't know if this is available for the d50.

edit: i had always heard the d50 was the same as the bj d60s from the C's out, so i guess the freespin kit would work with the d50s too. the shit is like $1,300 though. it does come with 35 spline outers... I'm not sure if you can run drive flanges with it.

here's the link for the lazy: http://www.dynatrac.com/products_freespin_ford.html


redit: if it has warn lockouts included, i'm guessing drive flanges are a go.

rereedit: i keep thinking of stuff. One of the theories i've heard is that the vacuum lines used for the hub engage/disengage tend to suck the grease out of the 'lubed for life' unit bearing. Anything larger than stock tires and they pretty much crap out at like 60,000 miles. They're supposedly good for 150ish with stock tires. At $600 to do teh axle for the damn unit bearings, two failures and you bought yourself the freespin kit.
good luck
Paul

Its a very common axle...you wont have a problem finding them; i dont know who told you that price...but my warns were $150 on ebay.

I think he's talking about the freespin kit. superduty 50s and 60s have vacuum actuated auto hubs with a manual mode, but the still rely on the unit bearing.

just a correction, that dynatrac kit is almost $1900. You could probably get regular balljoint+spindle d60 knuckles to work with superduty brakes for less than that.

Sounded like he was just talking about actual locking hubs...easy and cheap to cap off the vacuum tubes and run a manual locking warn or whatever brand.

but yeah, dynatrac isnt cheap...i would only use it if i had a superduty and it would be a pain to swap in a kingpin axle....otherwise id just buy an older D60

I would like to know more about the hybrid 44/50/60. Can anyone shed some light here. It would be a nice upgrade for those of us that already have a hp44.

agreed. i just figured if someone quoted him $1800 or something, that person was referring to the dynatrac.

i will say though, the vacuum hubs (when they work) are pretty slick. no getting out to lock the hubs up...

Iknow the TTB 50's were basically similar to a 60 on the spindles... (same stub shaft diametr, length, ectc) But they used a 44 joint... WTF were they thinking...

However, it would be a decent upgrade, I guess, for a D44... if you wanted the stouter shaft size, etc for cheap...

actualy the ttb50's dont use 44 sized joints, they use the bigger 1350's, with external c-clips.
