1998 Pontiac Grand Am Question: SHAKING/VIBRATING FROM FRONT END WHEN CORNERING, WHAT COULD THIS BE?

 

Question

Car is a automatic with the 2.4, My car shakes when you reach 30mph & mainly does it when going into right or left cornering, then continues to shake until about 70-75 mph. the worst shaking happens at about 50-60mph, it has gotten worse and worse to where it vibrates constant now. Here i Jacked The car up on a floor jack and started the car and placed it into drive, when it hits bout 3k rpm +, it shakes violently from the passenger side, and the whole strut/& wheel assembly can be visibly seen shaking. Can Anyone Give Me Any Advise On What This Could Be? Here I Was Thinking The CV Shaft, But In Past All My Other Vehicles Clicked Or The Shaft Flopped Around This Has Me Stumped . Any Advise Would Be Greatly Appreciated!!! THANKS!

    I have seen the inner CV joints cause similar problems, and they don't make noise. The joints get dry and they start binding, causing a vibration.
    Verify that the wheel balance is OK and that the transmission and motor mounts are in good condition and not broken. Make sure the suspension bushings are OK as well.
