Is it worth a damn? 6 or 8 lug? Too old to fool with? Balljoint or kingpin, high or low pinion, standard or reverse rotation? I'm sure it's leaf sprung, correct? I haven't seen it, only been emailed about it, no pics as yet.

JUNK
small D44 sized shafts, low pinion.
not worth it.

 

[makemeknowit]

Thank You.

 

[fordman7795]

high or low pinion, standard or reverse rotation

these two questions are asking the same thing.

 

[makemeknowit]

Thanks fordman, I'm still learning stuff the more I'm here. Too bad that some think you should already know everything prior to being here.

High Pinion = Reverse Rotation

 

[seboh]

No, high pinion = reverse cut or reverse spiral

There's no such thing as a reverse rotation housing, unless you're talking about the pigs under Tiny.

 

[fordman7795]

reverse rotation is the same thing as reverse cut as is the same thing as high pinion.

 

[dogonmut]

reverse rotation is the same thing as reverse cut as is the same thing as high pinion.

No. seboh is correct. Reverse rotation implies that the gear spins a different way. It spins the same direction as a standard "low" pinion carrier. It's called reverse spiral or reverse cut because the drive side and the coast side of the ring and pinion are cut in the oppisite direction of a standard R & P gear. This alows the forward torque to be applied to the stronger side of the gear set.

But all in all we are only talking about semantics.

But all in all we are only talking about semantics.

Exactly...and tons of folks CALL it reverse rotation...so for him to understand what people mean by it, is almost more important than actualy understanding the mathmatics of the inner workings....at least when it comes to chosing the right aplication for his rig...clear as mud?

 

[makemeknowit]

Ok, since I'm here to learn all I can about 4WD stuff and I have from this thread already, how 'bout this:

Are all high pinion fronts kingpin or are some of them balljointed?
If some are balljointed, which years or models or are there some of each(kingpin and balljointed)in the same year models?

 

[seboh]

No. All Ford D60s (and only Fords) are high pinion after 77.5. They're kingpin until 91, then ball joints from 92-97. Starting in 99 (no 98MY), they're the D50/unit bearing/metric pattern/ball joint POS axles under Stupid Duties.

And yeah, it was only semantics.

However, the axles under Tiny actually *are* reverse rotation. The centers are flipped to put the ring gear on the opposite side. They spin backwards from what a normal diff does.

Thank you seboh, and everyone else, for expanding my knowledge. :thumbup

I love this place!

Oh, and since I never even read the first question.... are you sure it's an F350? Ford didn't make a 4wd F350 until the mid-70s, right? If it's an F250, it would be a low-pinion closed-knuckle 44... but if it's really a mid-60s F350, I wouldn't be surprised if it's a conversion with a Nash (err... .Neapco??) axle... one of those big suckers with the removable center.

Ask over on PBB in the Ford Forum. I'm betting Alpo or P|n-ball would know.

I think you are right... I thought the first factory 4x4 F350 was 1979... but I'm not 100% sure.

 

[plug ugly]

shawn, just curious, but why does everyone say a d50 SA is a POS. The carrier is a 44 i know, but the rest is the same as a 60. How often are 44 r/p's actually failing? It seems to me that the knuckles, shafts/tubes and bj's are the weak point on a 44, and (except for the upper bj of a 60 being the same as a 44 IIRC) a 50 does eliminate a lot of the weak spots on a 44 and could prolly be had for a lot cheaper than a 60. What else is there?

 

[seboh]

D50 SA is unit bearing, necked-down shafts (about the same size as D44 stubs, if not a hair smaller), ball joint, and metric pattern.

And IME, they're about $2k in junkyards.

So if you wanted to run a metric 10.50 and replace ball joints and wheel bearings ($150ish EACH?) once a year on the D50.... it wouldn't be a bad idea.

 

[muddybronco]

Speaking of dana 50's, theres a d50ttb w/4.56 gears on eBay for $50 if you need hubs to convert a dually d60 front to normal hub style, or if you know somebody wanting to regear their f250 to 4.56... cheap way to do it if you're near IN :hump
