Front wheel bearings' signs of going south??
Soon after showing off my 5kcst's new found braking power to my
brother during the weekend, the front end of my Audi developed a very loud
'wo wo wo wo' noise whenever it reachs 45mph or higher. Btw, the noise's
tone will changed to a higher and louder wo wo wo wo as the speed
increased to 80mph.
I think the noise has already existed for sometime already, it just wasn't
as loud back then.
So, I did a lot of tests this afteroon.... including switched tires to
different conner and performed the wheel bearing test. However, the noise
is still there regardless how I switch the tires around(I even put my snow
tires on it). And, I found no play for both front wheels during the wheel
My question: Can the wheel bearing be failed even I found no play during
the wheel bearing test?
Or just something else that causes the noise?? Flat-spot-uneven wear
tires? How about the worn out a-arm bushings? I noticed the a-arm bushings
on my Audi are in really bad shape. Please help me guys.....
