 there any other suspension
 components that I should look at that may be causing this shimmy at high
 speed?. Apprecaite any help.

1. Rack & Pinion rack "play"
2. Improperly balanced tires (not balanced to 110 mph)
3. Belt seperation/movement in one tire.
4. Tire that was previously improperly imbalanced, now out-of-round/worn 
wrong.

Suggest re-balancing tires first on a Hunter of similar year-2000 balance 
machine that can replicated "spin up" speeds to 110 mph. When you get up 
there, you must have the tires/wheels PERFECTLY balanced, not just WELL 
balanced.
