This video compares the noises emanating from a Bad Hub/Bearing to a New one on a BMW 330i (E46) - Passenger side @ 97,251 mileage.

First you heard what a blown out hub/bearing sounds like, then after a new one has been properly installed... you hear the difference between them.

HOW LONG WHERE YOU DRIVING ON THE OLD ONE????

@FireBurningDesire

Probably for a good three and half months. The sounds developed slowly (barely audible). At first I thought it was tire noise < they were old anyways, so I rotated them.Thought that fixed it because the sounds changed ie: less noticeable. However, the noises came back several weeks later... which made me get new tires. But, the noise was still there and getting Louder to a point of major annoyance. That's when I took the whole thing apart and tracked it down to the bearings.

just a typical POS BWM, I have mine replaced once already and they are make that exact noise agagin...so frustrating

Interesting... usually when new bearings FAIL (prematurely), it's due to over torque. What torque spec did you install your hubs? Was it done with a Impact wrench, instead of a proper torque wrench? Also, what brand of hub/bearing did you use?

Funny thing you would complain... I was able to get 95+K miles out of the original bearings on my 330i BMW. And, considering the level of performance this vehicle has given compared to other brands of the same model year, there are no equal.

I have a RWD, so it doesn't matter which mode my transmission is in, since these were my front axles. If you have an Xi model, then perhaps you should set it to "neutral". The main thing about this process is you need to remove the brake calipers when you test.

That bearing says "FAG" on it.

@wootness3000

Hey r u doin that in PARK or in NEUTRAL

[bimmersgarage]

@frosty9595

That is absolutely correct.. and you can see it is as you stated when the brake rotor is off. However the rotor on, the weight of the rotor makes it appear much less so.
