2002 Camry XLE, 4 cylinder. About 97K miles, decent yokohoma v4s tires and have a 19mm rear sway bar (whiteline).
I just feel the handling of the car way too "loose" (for lack of a better word)

feels and unsafe in turns. Sort of a floating feeling like a boat. I don't have any suspension issues...
Questions:
1. Since I am close to 100K will changing struts/spring help? Could it be just the struts? or just the springs?
2. What struts/spring is recommended to improve handling? (I don't want to lower etc). (and where to buy?)
3. What's this poly bushing for the steering rack? (and how much work is it to put on?)
