Front springs? Strut inserts? both?
 

Hi All,

My 2001 9.3 SE is becoming un-drive-able due to the incredible amount of reaction in the steering wheel and steering column when i hit bumps, changes in road surface etc

A good size bump will literally shake the steering wheel nearly out of my hands, the vibration is tremendous

Running Eagle GTs on 16.5s well under max pressure. Car has 128k on it.

Replaced control arms last year - did not help at all.

Strut inserts? Springs? both? Is there a good "How to replace strut inserts" thread on this site?
