have a vibration at initial acceleration low speed or high speed, check front end over all tight nothing is found lose, check alignment come out OK, I thought the tires is an issue put on 4 new Michelin and computer balance and road force all the tire come out OK, but the initial vibration still there any advice? anyone ran into similar case like this one?

 

check your motor mounts, a broken motor mount could cause the front end to "vibrate" when accelerating

Just an idea, could have nothing to to do with your issue

 

I did check the motor mount none of them broke or bad.....the vibration only occurred on acceleration, put in neutral gone

 

Another thing that only vibrates on acceleration is axles. Particularly the inboard CV joints.

Lift the front of the car & support it really solid. Grab the axle & try to shake it. If the inboard end of the axle has some looseness, that could be the problem. Try to move the axle up & down, or forward & back. Not in the direction of the axle centerline.
