So the problem for me is, I have three different sizes of rounded hex sockets and no definitive answer on which size I need to order.

Yes I have autozone, oreilleys, napa, etc. No one has what I need or I would just buy some, and take back the ones that didn't fit. I do not have the time or money to order the wrong sized socket, pay to have it shipped, and wait for a new one to ship back out. My truck is currently up on a jackstand.

So to clarify, and simplify.

What sized rounded hex do I need to buy in order to removed the spindle nut off of my 1997 F250 Dana 50 IFS with auto hubs?

I'm just thinking out loud here, but could you swing it to order all three sizes and then return the two you don't need? I'm sure they're not cheap, but that's the only way I know of that you could be sure to get the one you need for sure without having to wait for the shipping three times over.

Either that, or if you can somehow get it off the truck and measure it, you could then order just the one you need to have for reassembly.

I've been right where you are buddy. Sit tight and I'll have a definite answer for you when I get home in an hourish. I also have lots of pics from hub disassembly that should help.

Technically I could swing it but am afraid it would put me in a bind waiting for the refund to hit my acct. I'm going to try and measure it with a tiny measuring tape or a piece I string. It would be hard to narrow down the difference of a 1/16" but at least I could narrow down the 2 3/4".

redman84 has a good reputation on FTE.redman84 has a good reputation on FTE.
Performance Tool part # w83246. 2-3/4"
Got mine at oreillys

As far as the spindle nut there is a lip on it and the internal threads have grooves through them as well but it doesn't look like in your pic there is anything else holding it on. You obviously made it this far but I'll put up these pics anyway for you to compare to and see if something was missed.
Hub


Cover Off


Remove snap ring from inside hub groove


Pull the auto hub assembly out


Looks like this


Snap ring off of groove on axle stub


Washer stack out from behind snap ring


Note: There should be three washers. They come out splined, plastic, and metal and go back in metal, plastic, splined.


Pull the cam out


C clip comes out next


After that is the spindle nut, bearings, and oil seal. I don't have any more pictures from there. Hope some of this helps.

  1. Remove C-washer or snap ring from stub shaft groove.
  1. Remove spacers (three thrust washers) from shaft.
  1. Remove cam assembly. Pull to remove.
  1. If front disc brake hub and rotor and front wheel spindle (3105) are to be removed, refer to Wheel Grease Seal and Bearing, Front Replacement and Repacking in the Disassembly and Assembly portion of this section.
Installation
  1. Align the fixed cam retaining key on the cam assembly (garter spring inboard) with the keyway on the spindle. Firmly press the cam assembly on the wheel retainer nut.
  1. CAUTION: Improper sequence of three-piece thrust washers will result in excessive wear of assembly.
    Install three-piece thrust washer set (first metal, second plastic, third splined) and retainer lock ring on C-clip. It may be necessary to push the axle outboard from backside of knuckle. Be sure retaining ring is seated in groove properly.
  1. CAUTION: Rotate moving cam stop (use any one of three) to the one o'clock position in relationship to the fixed cam retaining key.
    CAUTION: Do not force body assembly into front disc brake hub on rotor if body assembly will not fit. Recheck alignment of all components.

    NOTE: The hubs should not be packed with grease. Too much grease will damage the hubs and prevent proper operation.

    Install body assembly into vehicle front disc brake hub and rotor by lining up the three legs outside the hublock body with the three pockets in the cam assembly.
  1. Make sure body assembly is in far enough to see groove in rotor tube. Install large lock ring into groove of hub. Be sure lock ring is correctly seated.
  1. Install cap to body assembly. Install three capscrews and tighten to 4-6 Nm (35-53 lb-in).

Nice job redman. Reps sent!

To the PO, NEVER tell a parts store you have a '97 F250. Ford made both a LD and HD F250 in '97 and most parts store employees have no clue what the difference is. I always ask for parts for a '96.

If you can't get the nut to move more than just a little, check your retainer key (C-clip). The tip may have broken off and still be in there.

I bought the rounded 2-3/4" and had the same problem of it not fitting inside the hub. So I walked over to the lathe and worked it down just enough to fit inside the hub.
Thats the best advice I have because I went through this same thing. Bought 3 sockets and none worked until I took the 2-3/4" to the lathe and made it work.

Hang in there, these things are hard because almost no one has the auto locking hubs. My '96 has them and I wish my '97 had them too.

EDIT: If you have the C clip out, the spindle nut will turn off. There isn't anything left to keep it on.

Yeah I dunno why my autozone didn't have one. Such is life.

Redman, thank you very very much. I wonder if we could get your write up as a sticky? Maybe already is just didn't see it. I guess the reason why the one I had wouldn't fit into the hub is because it wasn't rounded on the corners, as from what I remember, it was where it came to a point that would hit the splines and not allow it to slide in. As soon as I get home I'll be sending reps out.

Good advice on going with the 96 vs a 97. I'll try that next time and see if it's any easier and gives them less confusion.

Now I gotta throw it back together to drive it, and do it all over again this weekend baring weather. The ball joints are very very bad. At least a 1/2" of play in and out.

You know what, after looking at redmans pictures, I don't remember the tab on the C clip being as long as his. I'll check that first thing. It would explain why I was able to back the nut out by hand but only up to a certain point.

IF it's broken off in there, how would one go about fishing out the broken piece?

Correct me if I'm wrong but isn't that nut what controls the preload on the wheel bearing? If that is the case and it isn't tight and you're driving on it, there is a good chance of messing up the bearings and spindle. Maybe I'm misunderstanding what it is that you're doing, but that's the way it looks to me.
