Thanks for responding Mike. The axle is most definately a Dana 44 IFS. I
have been trying to politely tell TheSnoMan it is a Dana 44 IFS, but now I
feel I need to quote the Haynes manual chapter and verse (sorry, I don't
have the Chilton's handy for quoting.). This is from the Haynes "Ford Pickup
and Bronco Automotive Repair Manual - 1980-1991 - 2wd and 4wd......" Chapter
13 Supplement: Revisions and information on later models. Page 326
"FRONT WHEEL BEARING (4x4) - ADJUSTMENT
Beginning in 1989, Broncos and F-150's and F-250's with Dana 44IFS driving
axles and manual locking hubs have a different front wheel bearing
adjustment procedure."
It then goes on to explain how to adjust the axle nut (singular) on this
particular setup. It is most definately the factory axle in this pickup. It
is also most definately, according to Haynes, a Dana 44IFS. The pictures
compared to my parts don't lie. Sorry, guys I hate to tell somebody they are
wrong after asking for advice. I just want to make sure we all are on the
same page and understand what it is going on.
The hub nut kinda has teeth on one side that are intended to bite in and
keep the nut locked in place. You see the same idea on locknuts for bolts.
They have the washer built into the base of the nut with serrations on the
flat.
I don't think it is so much the axle is too short, as much as it is
everything is riding too far in on the spindle. That is what my manual hub
is hitting against...the end of the spindle. I asked this question wondering
if anyone had seen a case where the entire hub assembly was riding a 1/16th
to an 1/8th too far inboard and how they corrected it.
Once again, I really do apreciate people taking the time to read my post and
help me brainstorm solutions. I really didn't mean to start an arguement
about what kind of axle is in the front of a 1989 F-250.
