Dana 44HD axle nut socket? Or is it a Dana 50?

Ah, ok, I didn't realize there was such a thing as a seven lug wheel on the later model F250s.
Although now that I'm thinking about it, I remember my brother in law had an F150 (2001 I think) with six lug wheels which we jokingly called a 5/8-ton.

The "standard" F-150 is actually the 5/8 ton.  It was made in the '70s as a heavy-duty half ton (to get above the EPAs GVWR limit requiring catalytic converters).

Similarly the "light duty" F-250 is the true 3/4 ton.  The F-250HD was a heavy duty version in the early '80s to get above the raised GVWR limit.

Of course the F-100 (true half ton) was discontinued.  And in '99 the standard F-250 (true 3/4 ton) was rebadged as an F-150 (called F-150 7700 for its higher GVWR, and still with 7 lug wheels).  So your brother-in-laws F-150 was likely a 3/4 ton.

Now the F-150 is either a heavy-duty half ton (5/8 ton?) or a 3/4 ton, depending on how it's optioned, and the F-250 is only available as a heavy-duty 3/4 ton (7/8 ton?).  But the real bottom line is that the "ton" ratings mean absolutely nothing anymore (if they ever did).

Yes I mean the oddball 7 lug 250's.
What was Ford thinking?

I would much prefer a meaningful tonnage rating. GVWR - Curb weight = X
100, 150, (200 in Mexico) 250, 350, 450 (as far as normal size pickups go) doesn't say much about the load unless you know the year. And what it meant in that year.

So 1/4, 1/2, 3/4, 1 & 1+ ton rated would make more sense to me.
But I'm not wired like most.

Truck looks great!
