well parts I would assume would be anywhere from $90 for the pair to as much as $100 each depending on where you look. If you aren't going to Audi see if you can at least buy the bearings yourself, you could probably save a few bucks.

The gimme is the fact that I believe the easiest and correct way to get the bearings out, is to press them out of the hub. I don't know if there is another secret way but this is what I had to do. I figure if you schedule for service at the shop and they don't dick around, I'll err on the side of caution and say 2 hours tops. With the bulk of that just removing the pieces that connect to the hub. The only other issue that came up with me was you have to remove the ABS wheel speed sensor to get the hub out and when I pulled mine believe I may have damaged them because I have the ABS and Brake lights on (could also just be ABS module) If the shop damages these, they are about $70-90 each on ECS Tuning, you might find a better price if you look.

Now this is just an estimate. By no way am I saying that this will be the case. This is just what I did. I removed the hub myself in about an hour so a mechanic could probably do better, removing and pressing the bearings is easy if they have the tools.

So in a long story:

about $90-200 in parts (depending on where you look)
about $65-125 in labor/hr. (if you go to a independent shop vs. Adui)
I'd say between $220-$450

Then again....I could be wrong......I know you are looking for a definite answer maybe someone else will have a better idea.

Thank you. I'll call around tomorrow. I think there's only one shop in town that would be willing to do it.

That makes sense, as I'm only getting 25mpg highway.

Just scheduled the repair for Wednesday. I went with the cheapest quote I could get from a reputable shop, which was $214.50 for parts and labor for the right front bearing. I intend to change all four bearings in a year or two when I get all new suspension anyway, so I figured just changing only the problematic one for now would be sufficient.

They're installing a bearing made by a company called ***. They say they're a very reputable brand. Despite the strange name does anyone know anything about this brand?

looks like I wasn't too far off on the quote. I would still replace both fronts but that's just me. Never heard of *** bearings but as long as they fit and they are new you should be good to go.

Yeah, that's what I figure. I chose not to replace both because I want to replace all four at once along with my all new suspension when I get the time/money. That way I shouldn't have to worry about any of them for a long time afterward.

if you are turning left and the noise stops, wouldnt that mean the left is bad since you are unloading the left wheel in a right-hand turn??
