When i launch from a light i get a slight vibration from the rear of the car and i just wanted to know if this is normal? This is my first AWD car so i don't know what is sounds or feels like. I have heard a lot of people breaking axles and i am not sure if this is what this feel like when one is loose. When i go to 2nd i don't feel it anymore so i really don't think it is the axle. If this is a normal feel then i will let it go. i have about 1700 on the car as i have had it 5 weeks.
