'86 5KCSTQ Front End Shimmy

[Mark Pollan <0002009911@mcimail.com>]

All:

I seem to recall a thread on this not too long ago but can't find in the archives.

Iv'e got an intermittent shimmy under braking sometimes more violent than others.
Shimmy seems to be worst when I'm dropping through the 65 to 55 mph range.  The
perplexing thing is that it is intermittent so I have pretty much ruled out warped
rotors.  CVs?  Ball Joints?

She runs smoothly up to and beyond 90mph.  Do it daily so I don't think it's
wheel balance either.

Any thoughts?

TIA, Mark
