I have a whining noise that I thought was a wheel bearing but my mechanic thinks it's the rear differential. I have an appointment with the dealer next Friday to have it diagnosed by them.

If I need my differential bearings replaced (rebuilt), is there a good place around the western suburbs of Philadelphia to have this done?

I did a web search and found Chester County Transmissions and they said that they could do it but I was hoping to find a place that specializes in BMW but won't charge as much as the dealer.

My car is a 2009 E90 xDrive manual trans with only 38,xxx miles. And I baby it. Has anyone heard of a similar situation?

Thanks

It came with staggered 225x40x18 front and 255x35x18 rear style 287's but I swapped out the rear wheels and all 4 tires at 28,xxx miles and went with a totally square setup (225x40x18 on 8.0 x 18 all around).
