I get a vibration when driving that I can feel through the steering wheel only when the wheel is turned to the left. Straight and to the right, no vibration. I hear no noises, clunks etc. I even tried turning in a circle all the way to the left and no noise. It feels like I'm getting resistance when I turn to the left while driving (such as bends in the road etc.). The steering wheel doesn't shake but you can notice the resistance and vibration. I'm thinking bad strut.

The only things I've ever known to cause a "vibration" on a turn are:
Severely chopped tire on the inside of the tire.
Loose lugnuts.
Badly worn wheel bearing.
Worn CV joint starting to lock.

Never heard of a strut causing a vibration only on a turn.

Hope this helps.

Will it do it when not moving? Could it be from belt slip on the power steering pulley?

maybe not the strut itself. but the upper mount will cause a vibration.

if you lift ur car off the ground. grab the spring, and try to shake the whole mcpherson unit. it should be pretty solid.

Only while moving. Today I was driving straight going about 35 and just turned the wheel to the left slighty and back to center(Not enough to really move too much) several times in a row and could feel the vibration. At straight wheel no vibration or noise. Any deviation to the left I get the vibration and a slight moan no matter how slight or how far to the left. Do you think a bad spring could do that? When I hit some bumps I can feel some vibration like that I feel when I turn left.
