I drive 2000 Audi A4 Quattro and latelythe carhas vibrating sound coming from the rear of the car and this happened 2 weeks after I changed all my tires. The weird thing is when I steered my car to the left, the noise or vibration is gone. Would anyone tell me if they ever had this kind of issue before? and pls give me some suggestion what I need to check before I go to the Audi dealership. I have a feelingthis problemhas something to do with the rear tires. I have done the alignment but still didn't fix the problem. Thank you.

 

turn your subs down....

did you do the alignment yourself? maybe it wanst done right?
or maybe you have a bent rim that could cause vibration adn more so when you turn a certain way..

 

take it to the place were you got your tires put on and tell them it started making this sound after, and see what they do. do not take it to the dealer

 

Possible bad or unbalanced tire, Possible wheel bearing going out.

Start with taking it back and make sure its not the tire. Or if its coming from one side, try swapping the tires and see if the noise follows the tire. Like switch the right rear with the right front, and see if the noise moves to the front.

 

^ good advice, just please dont go to the dealer

 

+1 on the unbalanced tire, and also check to make sure all your lugs are torqued properly

 

my car was vibrating when i went 70-80, but when i got new tie rods it went away.

 

Wow..thanks for the quick responses. I did have a tire puncture on the left rear tire when I had to replace all of the tires. I was going around 50 mph when I learnt that the tire was busted. I will check and try to do all those things you mentioned. Thank you again.
