In this video I am going to show you how to remove and replace a front wheel bearing on a 2006 Audi A4 Quattro.


Tools Needed:

17mm hex
21mm ½” socket
12mm triple square
Chisels
Hammer


Bearing Diagnosis:
I began hearing a low humming sound from the front once I hit 40 MPH, that slowly got louder as the speed increased. This is how I figured out what wheel had the bad bearing: On a straight empty road, increase speed to 40 MPH and lightly turn left and right. When you weave back and forth, you increase and decrease the weight of the car that each side has. When you go left, the weight shifts to the right of the car, when you go right, the weight shifts to the left side. A bad bearing will increase in sound when more weight is placed on it.
In my case the sound was louder when I was going the left, so I knew it was the right side bearing.

Torque:
17mm Axle Bolt: 200 Nm + 180 degrees
12mm bearing assembly bolts: 80Nm + 90 degrees
21mm caliper carrier: 30m
