I am having a wierd issue. Whether I am accelerating from a stand still or going HWY speeds. Going straight or turning there is a sporatic hard pop in the front end of the car. I don't feel it in the stearing wheel but it jars the crap out of you. At first I thought is was a CV axle slipping on the driver side. I had replaced the passenger side last summer so I went ahead and replaced the driver side. I checked the ball joints and tie rod ends and they seem ok to me. When you are standing outside of the car and someone is in the car driving it up and down the driveway and it decides to pop, the wheels jerk in the direction that the car is moving. Again you don't feel it in the steering wheel. Last fall I replaced the the motor mount on the passenger side and the one that is on top of the tranny. Any help is greatly appreciated.
