RE: 86 5kcst brake shimmy

["Pat Dooley" <pdooley@gte.net>]

I inspected the sway bar bushings when changing the lower control arms.
They looked fine so I didn't change.  The wheel grab/shake test should have
revealed any shortcomings.  Maybe I'm putting too much faith in a crude
suspension test.

Anyway, I noticed a couple days ago that the caliper guide pin bushings were
badly worn on the driver side caliper.  Incidentally, the driver brake pads
were more worn than the right side.  I attributed this to a sticky caliper,
but maybe the worn bushings were causing problem.

Now to source out some bushings.  Gotta love these high mileage cars.
