Ken S.,
I just got off the 'phone with Bob D., talking about your dilemma. I tried
to call him back with the outer dimension of the bushings I have: 1.680"
I was going to suggest checking the inside of the hub to be sure whether
the bore is the same all the way through -- Jim H. just confirmed for us
that it IS NOT. There's a stop shoulder, as I feared, so using that
dimension for a "drive-it- outer" won't work.
It's been over 20 years since I did my bushings (meaning they've needed
more attention for at least 20 years). I did them at the GMC Coop,
following Jim B.'s suggestions. That was to use a muffler chisel in an air
hammer to remove the bushings. That worked, but I also made at least one
groove in a hub -- bad juju. If I were doing them now, I'd either follow
Jim H.'s procedure or CAREFULLY use a manual muffler chisel -- NOT a
powered one. If you aren't familiar with a muffler chisel, it has a flat
blade, the end of which is concave so that it "peels out" a 1/8"+ path
through what it's driven against (normally sheet metal), hopefully without
affecting the adjacent surface. That is, it's intended to cut a muffler
flange off without damaging the exhaust pipe.
Not many of us have the blind puller Jim H. also suggests.
If Jim K. has a better suggestion, please share it with the rest of us.
