Keith,
I used locktite when I first installed and that left some witness marks
on the rearward portion of the u-joint outer surface, where it enters
the carrier bearing. It was obvious the joint had only entered the
bearing about 3/8". Carrier bearing is brand new. First install was done
by brute force, and it took some. It did NOT slip right in.

After measuring the other day I determined that the joint needed to be
seated about 20mm deep(from memory). So, I did the hot/cold thing
(recommended by John Prusnek) on mating parts and it went in pretty well
and the proper distance.

Don't know if that is clear or not but feel free to ask for more sloppy
descriptions.

When I had the swingarm out of my Ambo several weeks ago, I had the same

problem on re-assembly. The U-joint had slipped forward out of the
carrier bearing and wasn't seated properly, therefore, the swingarm was
not aligning on the right side. Took me awhile to figure out why the
U-joint was sliding all of the way up onto the tranny spline but the
swingarm wasn't aligning on that side. I stood the swingarm up on it's
end and slipped the U-joint back down inside and tapped her in, then
realized it wasn't seated. Re-installed without any issues.

My question is, Ray said the following:

"Then I looked at the end that was installed in the carrier and noticed
the marks showed it wasn't fully seated. So a few measurements with the
calipers and a plan for identifying proper seating were devised. Joint
in the freezer, heat gun on the bearing. Some dead blow hammer whacks
later, using an old messed up driveshaft as a tool, and down it went."

I'm confused on this part. What marks are you referring to? Where is
the fully seated point on the U-jon? I was able to tap my U-joint in
pretty easily, no heat or whacking needed. Did I do something wrong or
is there something wrong with my carrier bearing? If it is worn,
perhaps this is why I am getting oil migration?????
