I need to buy some manual lock hub parts for my truck. I don't know if the diff is the Dana 50 or 60. There is no tag on the cover bolt. How can I find out which one I have? There is a casting number 620093R stamped on the axle if this means anything.

 

you can go to www.dana.com/ and use their library theres a little drop down menu hit expert system and then catoalges and liturature and there's manuels to show how to find and use the bom # (bill of materials).

 

pretty sure if its for your 91 F350 there its a 60, but
i think they take the same locking hub anyway?

 

I think northern7.3 is right...

 

Dana 50 and 60 both use the same lockout hubs.

91 solid axle was a Dana 60.

 

what years did they put in a solid Dana 50 in the F350?

 

'99 Super Duty, Non-dually (SRW)

 

'99-? Super Duty, Non-dually (SRW)
I don't know when they stopped putting the D50 in the SRW Super-Duty for sure but most sources say '01 or '02. All Super Duty F-250s and F-350s started getting D60s then.
They also have unit-bearings and funky working hubs.
In '05 they also went to a coil-sprung suspension much like the '94-up Dodge but with beefier components.

 

i didnt know Ford made a 4x4 dually before the super duties...(99+)

 

Oh yeah, lots of them.


BTW, as far as I know all factory dually 4wd. trucks were 1-tons and were equiped with Dana 60s, no matter the manufacturer.

 

This truck came from Ford as a 2wd. Quigley in PA converted it. Is the axle shaft and universal different between the 50 and 60? Thanks for all the help.

 

Be carefull there if it is a conversion.

The local fire department had a 450 crash truck converted to 4x4 when they installed all the fire equipment.
The axle the conversion company used for the conversion was some closed knuckle Chinesse axle, I did a search on the name and the only thing I could find that used axles from that manufacturer was Ditch Witch.

Looked like a 1960 closed knuckle Dana 60 untill you really started looking close.

Wish I could remember the name on the axle.

I was looking at the truck with intentions of buying it for a service rig with the very nice utility body it had.
After I found out that parts were not available for the axle, it went to some other lucky soul.

 

ah, quigley...we have a bus at work (actually three, this this one) that snapped both lower torque arms off today for no apparent reason :shock:

 

No wonder you went to look at it, that sounds like a cool rig! I probably would have looked at it, thought it was a Dana (or surely something you could get parts for) and bought it. Then wanted to shoot it later.

BTW did it have 10-lug hubs/rotors, must have (shoot it could have had drum brakes if it had a Chinese axle anyway)?
I've always kinda liked the idea of a Quigley 1-ton, 4wd van with an IDI. Ive always read their van conversions (8-lug) were D44s or D60s, you can bet if I ever find one cheap enough to go look at it I'll be checking the X-case and front end REAL good now.

 

When I was first looking at it, I thought I had found gold.
If I remember right it was a 93 7.3 turbo with a five speed.
Gen set built into one of the lower compartments, diesel engine on the gen set plumbed into the truck fuel system.
Power outlets several places on the body, built in quartz lights that extended and could be aimed any place you needed them to shine.
There was also an air compressor powered by the same engine with a 50 gallon storage tank.
Plenty of bins, drawers and compartments for tools.

Had a 200 gallon water tank and pump in the back, but the department was keeping the tank and pump.

Well taken care of.

I saw the truck was 4x4, but no transfer case shift lever, just a **** like a PTO would have with a cable down to the transfer case (I use the term transfer case very loosely here).
I called it a transfer case, but single speed in 4x4 or out 2 wheel drive.
Then I start noticing things like the close knuckles and 8 lug front wheels.

One of the firemen start telling me about having it converted to 4x4 after they bought it so they could make it to calls when the roads were bad.
Since it was their crash truck, I guess that would have been rather important.

But it did not work out for them to well, when the water tank was full and all the equipment was loaded, with no low range they ran out of power on some of the back road hills around here.

Even though the price was right, I left it there.
Now when they replace the F550 crew cab 4x4 they have now, I might have to look again.
