i just put new axles on my car today and i noticed right away my car is shaking at take off and then seems to go away. it does it both while turning or going straight. please help my da is riding way worse than before.

 

I changed them for him and a more detailed description is: there is a vibration in the car. It doesnt make the steering wheel wobble or shake so I assume its in the rear, but he says it didnt happen before today. It is predominant on acceleration from a stop through the first few gears. Not so much while cruising, but it is still there.

he had the tires balanced the other day.

I searched and found that some people were getting bad axles from the store and had to change them out a few times before they got one with good cv joints. Is this a true possibility?
