A4 Rear End humming noise
Hi all, I have a problem and I hope some of you might be able to give me
some help. I have a 2001 A4 Quattro, 5 speed. It has 60K miles on it. In the last week or so I've noticed that there seems to be a humming type of noise coming from the right rear (I think...sometimes noise can be deceiving). The sound almost seems like the noise you used to get when you put snow tires on a car. My tires are in excellent shape, so I don't think they are the problem. The sound is more noticable at higher speeds and increases as speed increases. If I put the clutch in, or shift to neutral at a high speed (60mph or so), the sound remains. I haven't noticed this sound before this. I am thinking something in a bearing or axle? What are your thoughts? Anyone experience anything similar to this? I'm not too familiar with Audi running gear (axles, bearings, CV joints, etc.), but I am a pretty fair backyard mechanic, so I will be able to comprehend any suggestions. Any help or suggestions would be greatly appreciated. Thank You |

On the good side though the bearings are sealed so they wont fail they just keep getting louder and louder untill you can no longer bear it anymore |

If you let go too long they'll take out the hub and the hub carrier. The hub carrier = very expensive. Very easy to do if you have a arbor press or something like a hub tamer. I just did my rears I few week ago. About a 3 hour job once you know how to do it, 4 or 5 the first time. --Vic |

Not bad, not cheap but not outrageous. The dealer wanted $1200 to do all
four on my car. I said forget it and did it myself. I paid $120 for rear bearing and $270 for a hubtamer. Now I have the tools on top of getting the job done for less than the dealer. The parts are $120, labor is four hours for 2 rear bearings, $300, 4 wheel alignment =$80. Local garage get about 75/hour so total is about right. >> > Thanks for all the advice.

Anyway, I'm happy that my A4 is quiet again. |

Anyway, I'm happy that my A4 is quiet again. It was a bit under $300 for a local shop to do one of mine and a bit over that for the dealer to do the other. (They didn't fail at the same time.) -- John Carr ) |
