Long story short.
For the last few thousand miles my 99.5 jetta has been making a popping noise (many pops, not just one) only when turning right under accelleration. (No noise when coasting or decellerating in gear and turning right, no noise under any circumstances). no pulsing in the brakes, and the car appears aligned well as it tracks nicely.
The noise is rotational, the faster you go, the faster the pops happen (again, it will make many popping noises, not just one). Probably once per revolution on the tires, not entirely sure. And it is, with as much certanty as i can have, coming from the front passanger side of the car.
I took it into the mechanic twice, first time they couldnt hear it and sent it back. Second time they said it was likely the CV joint so replaced both on the passnager side.
I have to admit that I didnt notice the noise for about 300 miled after that service, and I did try to get it ot happen.
but its back now.
All boots and ball joints look ok and no grease has slung out. I am thinking it might be a wheel bearing at the extremely early stages of going.
Right now i am on a "wait and see if it gets worse " course. For the last 1500 or so miles it has not seemed to have changed.
Appreciate the input!
