Sorry - it is a Ford 9". I tried it with the wheel, per Big Al. Did
not work. Plus, since it is a Traction Lock, if I turn the wheel hard
enough, the diff will turn, even if in gear.

That's what I wanted you to do. Turn the differential. That's why I asked
you to put the wheel on. Any chance at all that you accidentally swapped
axles? Why not pull the other side and see?

I can't see how I possibly swapped the axles. I kept the left axle on
the left side of the car and the right axle on the right side of the
car. Any other thoughts that would cause this hang-up?

No. On a 9" with a stock carrier there should be no hang ups after the axle
starts in the side gear. Unless the bearing is hanging up in the axle tube?
You say it has a "Traction Lock." Is that something other than a stock LS
unit? Look through this and decide if it's really a Traction Lock. But if
it's a Ford factory carrier, makes no difference, the axle should go right
in.

Is there a chance the spline on the axle is twisted? About how far does it
go in before it hangs up?

I would withdraw the installed axle and try the other one. If it goes,
re-do the first.
I have a screen door with a lock that will accept its key either from
inside or outside, if alone, but will not take a key from the outside
if the inside has a key in the lock, and /will/ take a key from inside
when the outside has a key in it. Weird.

You say you changed the pumpkin, and that you have 28 spline axles. Was
that pumpkin rebuilt? A junkyard pickup?
I'm wondering if the axle carrier in the side that won't go in has been
changed to 31 spline somehow? Either a mixup at a rebuilder, or some
shade tree genius had one 31 spline axle, and changed the pumpkin to
accomodate it. A dirt track racer who wanted a 31 spline on the side with
the power tire?
I like the design of the 9" with the pumpkin, but at this point, it would
be great to have a cover that you could take off and actually see what's
going on.

Got it figured out (finally). Had to take it in. What was happening
- the metal gasket behind the brake backing plate and the axle mount
was bent in ever so slightly so that it was acting as a wedge between
the bearing and the axle housing. Because of this, the bearing would
not seat all of the way.
