OK Steve----I think the verbage led you to reaD THAT i MEANT THE DESIGN WAS BAD(sorry about the caps lock)
Here's where I am pointing the finger---A RAG JOINT won't fix the PROBLEM!!! neither will tightening up the adjustment of the rack( Sorry Blas)
The shake is coming from something that can generate a force back thru the steering parts---this can be from wheel balance, out of round, etc---it also can come from caster, ball joint to tire patch alignment, etc----
There are systimatic processes to determine when it does it( 60-85 mph)---is that in a straight line??? how about a long turn to the left??? right??? under braking???these are just some basic examples of ways to isolate this vibration/shake---
In addition to all the suspension sources for shake/vibs---aero can play a big part at those speeds---a small panel can cause enough buffet to shake a 2-3000 lb car---
