[s-cars] Shimmy nearly gone

[Robert Myers]

Hi Y'all,

Well, it appears that my SEVERE shimmy during 85 mph left hand sweepers is 
MUCH IMPROVED but is not gone.  Wednesday we replaced the lower control 
arms.  The bushings, after 220K+ miles, were toast - not terribly 
surprising.  Driving the car showed that the violent shimmy is gone but 
there was still some vibration which I attributed to driving on square 
wheels.  The tires on the car were down to the wear bars and I figured they 
were no longer fairly well balanced.

That evening my local tire shop balanced and installed the brand new tires 
(Bridgestone Potenza RE750 245/45R16 if it matters).  At highway(+) speeds 
there is a vibration which feels like an unbalanced wheel.  It becomes more 
pronounced during left hand sweepers at speed.  Either the balancing job 
was poorly done or I'm still having bushing problems.

Today I plan on checking the balancing.  What other bushings could cause 
this shimmy only in the RF corner?
