Hey 2000 A4 Quattro Turbo Tip.

About three months ago I replaced both wheel bearing in the back of my car. Because a very loud noise was coming from the back of the car cause defective wheel bearing. And now all sudden the same loud noise appear out of no where. That loud noise Honda's make with big muffler & rattling all the inside of the car. The loud noise appear the minute I step on the gas pedal & still goes on even when I take my foot off the gas. It's very loud & anoying & could hear it throught out the entire drive. Tell me what to do because I plan on changing the wheel bearing again but I can't keep on replacing these thing every 3months. So what can I do to avoid that problems P.s I avoid hitting potholes with the car.

 

Have you checked your exhaust piping?? Could be a fuel pump going bad too. I doubt its your wheel bearings because it would be constant if that were the case. Put it in neutral and hit the gas, if it happens then, its not your wheel bearings. Does it happen while you are coasting with no gas?

 

Wheel bearings tend to go out in pairs. I also replaced both of my rears a couple months ago.

There's not very much you can do. They wear down and have to get replaced.

Is the noise coming from the rear again?

 

Given how the bearings are loaded when the alignment puts outta spec forces on the bearings they are forced into a thurst load. This can kill bearings very quickly. They go out in pairs because they just divide the force between themselves

 

Yes I hear the noise while coasting with no gas, but not as loud as when I put my foot on the gas pedale. Yes the noise start from the back of the car & end up in the front & there's movement also and feeling the car shaking. But it's the noise that bothers me cause during the past couple of days it has getting worse & very loud. Any suggestions on how to approach the probl. I had a certified mechanic check it & he said that it was the wheel bearing but aslo said it's only one side that needed to be change not both. So if both sides usually get defective together y this time it's only one side? I don't know for sure if it's the wheel bearing or something else that cuasin the probl. But the loud noise sound exactly like the last time.
