How It's Done (how I did it anyway)...
With the front axle disassembled, now was a good time to take care of
flipping the tie rod. For easy access I clamped the outer knuckles in the
vice but it can just as easily be done on the vehicle. In a nutshell what
I'm doing is reversing the taper of the hole that the tie rod ends pass
though. The idea is to ream the hole from the top down but only go
half way down. The cones, which are inserted from the bottom up, make up
the rest of the taper and essentially reverse the taper so that its wider at the
top and narrower at the bottom.
To the right, you will see the stock ball joint in place as it would be in
it's stock location.
I took the reamer and placed it in the existing hole from the bottom up. Then
I and made a depth mark with a black marker. This will indicate the depth
of the hole the reamer will make from the top down.
Then, from the top down, start drilling with the reamer. I used a hand
drill to take out most of the material I wanted to remove using the drill. Then,
so I didn't drill too far I did the final small amount by hand. The last
thing you want to do is drill out too much material.
