(Sorry I know its a lot to read) Hey guys I am having a real fun time with this repair.....to be honest over a week I have ordered 2 different hub/rotor assembly's from Carquest and both have been the wrong hubs, first hub sent the studs (1/2) are to small for my trucks lug nuts the second hub sent had 9/16 studs BUT nuts off my truck wont thread on??? maybe wrong thread??? (left hand/right hand thread....IDK !!!) also hub was smaller than what came off truck.

I told them its a 86 F250 XL 460 4x4 D44 8 lug 6.5, and yet they keep getting the wrong 8 lug hubs sent to them,now they tell me they cant find one for my truck at all and it MUST be a junkyard part for me.

I will go back to NAPA tomorrow (if there open on the 4th) and see what they got again.

Right when I think I got it all figured out it ends up being all wrong !
I see that my trucks sticker says 3,800 front and the studs on my truck are 9/16 BUT all the HUBS listed at CQ and NAPA (and other internet websites) that are listed with 9/16 studs are rated at 4,800 pds (front) !

Why does my sticker say 3,800 (front) with 9/16 studs ?

Should I just get the one listed as 4,800?? why are there different wights for anyways? What a mess.

Also I got a few pics I would like to show, one is my trucks spindle can you guys tell me what you think? Do you think that it looks like a race has been "fused" to the spindle? Do you think the spindle is usable still or is it beat up looking to you?

Also so far I have only fond one destroyed bearing on this wheel.

where is the spindle bearing and the inner and outer bearings LOL ?!

Your axle should have a tag on it; post its info.

 

That inner race should come off fairly easily. Brass punch and hammer.

Dana 50?

 

Sorry but theres no reading this tag its long gone.

Ok thanks Ill try that tomorrow, I would rather it be a D50, I think.........

Anyone know if D50 hubs can be installed on a D44 ?

 

Hmmmm........ that's really too bad.

I can get still maybe find a little bit of information if you post a picture of the certification label from the driver's side door jamb.

 

I believe you can, but I think you'll have to change each end where the hubs go to a Dana 50 setup.

This truck is an 8-lug truck, so more than likely a Dana 50, but you could still have a Dana 44HD if your truck is a light duty F250.

On a Dana 44, the hub is slightly smaller than the mounting flange it was bolted to. On a Dana 50 and Dana 60's, the hub is the same size as the mounting flange. This should give you a clue as to what you've got for a front end.

The weight ratings for the front, rear, and the gross vehicle weight ratings as well as gross cumulative weight ratings are all necessary so the driver can safely, and in a lot of states legally, put the truck under a load. For instance, you have to know the front gross axle weight rating and choose an appropriate snow plow so the front isn't overloaded. You have to know the rear gross axle weight rating so you don't overload the bed of your truck. You have to know the gross vehicle weight rating so your truck isn't overloaded with the combined weight on the front and rear. If I remember correctly, the gross cumulative weight rating cannot go over the gross vehicle weight rating (cumulative rating is when you add like a trailer or a tow dolly or something similar, plus whatever is on the trailer). To make sure you don't go over the weight ratings, you would have to equip your truck like it would be fully equipped (full gas tank, you and whatever passenger(s) may be present, whatever tools etc.) minus the load, and go have the truck weighed at a weigh station. Subtract your weight from the GVWR and that's what you can tow/haul.

All of this is necessary so you'll be able to stop the vehicle safely and drive safely. Your motor won't have any problem pulling it, but the problem comes in stopping and turning.

You can look on the drivers side door jamb sticker, if it's still there, to read all the ratings your truck is equipped for.

 

Can't do it, the dana 50 has a larger bottom ball joint with a larger hole to receive it.

Not true, the only major piece that makes a f250 "light duty" is the rear axle. The dana 44hd was standard on regular cab f250's, light duty and heavy duty. The heavy duty truck will have a full floating rear axle assembly(has the thing sticking out in the middle of the wheel with the little bolts on it).

This is true, the dana 50 and dana 60 have the same size outer pieces and can interchange, except the dana 50 spindle will not have a tight fit onto the dana 60 axle, but it will bolt on and work.


If you have a twin-i-beam 4x4 frontend and your weight rating is in the upper #3000lbs area, you have a dana44hd. If your tag or the parts person is giving you parts that are in the #4000lb range, and you still have the ttb, then that will be dana 50 parts. I am not sure what the wieght rating is for the solid dana 60.

 

Didn't know all that Franklin! Thanks for the corrections! Would've gave you a rep but I have to spread the love.

So if the Dana44HD was standard, why would the other trucks come with the Dana 50? Just because of a higher front GAWR?

 

The early f350's from 1980 to 1985 1/2 came with the dana 50 because of the higher rating of the truck(f350)

All extended cab pickups came with the Dana 50 because the truck was larger and heavier, so they needed the heavier rated front axle.

I have heard, but never personally seen, that there were special order regular cab f250's that came with the dana 50. I have never seen anything officially saying this wasn't true, and I can possibly see someone checking off the heavier axle if they wanted to, it's not like it would be a problem for the factory, it bolts right in. So I will leave open the possibility that you could get a regular f250 with the dana 50 front. Of course you may see one once in awhile, but like I said was it factory or was it swapped in?

 

A version of the camper prep package, the snowplow prep package and the max front gawr package got you a d50.

As for the studs, I have never seen an 80+ 3/4 ton with anything but 9/16 studs, 44HD or 50.
If the studs are the only issue, just swap yours over. Why are you replacing the hub/rotor assy and not just the rotor alone anyway? Once you drive the studs out the rotor comes off.

 

If I were Ford and offered a snowplow package, I would make you buy a f350. I am not sure about the camper package though. I am just trying to think like Ford would, which is impossible sometimes with all the politics of running a business and dealing with government regulations.

 

The 250 was handy because at least in MN it squeaks under being taxed on GVW so you can have cheaper tabs, and IIRC they fit under the same regs in other states.

 

Well I just figured the hub would have been damaged due to driving the truck (not knowingly) for a while with the barerings all destroyed, wouldn't the hub have been riding metal to metal on the spindle or a race from a baring that fell apart ??

Trust me I would love to just snap some barerings and a rotor in it and be done with it but I think I went to long before fixing this repair and that just sounds WAYYY to easy a fix for me in my case.

I think* I need new hub (drivers side only) and for both sides new studs,lug nuts,barerings,rotors,calipers,pads and maybe a new spindle (driver side) that's just about my worst case scenario...so far.

also the last day I drove the truck I lost all braking power but I dont see any fluid leaks anywhere yet, the rotors both have 1 large and deep grove on them both sides and both driver/pass rotors have this, looking at the caliper and pads I took off I dont see what could have caused these deep groves?

Maybe they have been there a long time I just never notice it I really have not owned this truck long enough yet....I starting to know it now though lol.

Oh and BTW in case anyone has not realized yet and I probably should have mentioned already that I have never done this kind of repair before and really have no clue what im talking about or doing so I apologize for any ignorants. (hope at least I spelled that word right lol)
