The wear on one side is common, I think, because the pin only moves in a
short arc with all the weight of that corner of the car on the top side of
the pin. My guess is that the bushing is worn the same amount. Sounds like
the PO did not grease the fitting regularly, which would hasten its wear.
The best fix, unless you really want to get into a big time job of alignment
and silver soldering of bushings is to trade out the A-arms for rebuilt ones
with new fulcrum pins. A useful modification, when you get the rebuilt
A-arms, if you go that route, would be to drill and tap the REAR bushing for
a grease fitting so you can pump grease into the forward AND the rear
bushings. You were very lucky that you could remove the fulcrum pins that
easily. It usually takes cutting, heating, a BFH, and an act of God to
remove them.
