I have a 2011 TSX. The car has developed an inconsistent shimmy. It is not severe but it inconsistent. It typically happens going up hills under acceleration or corning under acceleration. I have changed tires and had an alignment done but it still persists. The car was hit on the front right corner, but this developed quite awhile after this incident. Any suggestions?

 

The axles are prone to pitting, which makes them shake.
