2004 Chrysler Sebring Driving Vibrations ?!?!?!?

[Erik]

Ok so here's the problem....My car started to have this weird vibration problem, while driving as i give it a little gas to accelerate i feel this vibration...It doesnt seem to be a engine problem i recently gave it a tune up my engine light has never turned on...From a stop i can acceleratae and vibration starts at around 35mph and so on...NOW, i know its not my tires they are brand new and are balanced...It only shakes while i give it gas, while im at a steady speed its fine....The more gas i give it the more i feel it...So here's what i think it might be im not sure...i noticed grease on my rim so i looked closer and it appeasrs to be coming from my cv joint...can it be that the cv joints loss of grease is causing this? Like when i acclerate the cv joint spins since there is little or no grease its causing it to vibrate which is why i feel the vibaration at my wheel / s......Or can it be my wheel bearings...I hear this weird sound as im driving and turn slightly right to merge onto another lane when i center the wheel its stops if i turn slightly left it doesnt do that....So im thinkin it has to be something around that either the bad cv joint or a bad bearing but i think its the cv joint since grease has been leaking out of it for the past 3 weeks or so....and thats when i noticed the vibrations while accelerating...let me know what you think....My tranny has transmission fluid no oil leaks from engine or tranny....
