I was hearing a lour roaring noise while driving. Took my car to the dealer and they told that both the Rear Wheel Bearing Hub Assembly need to be replaced. The dealer said they have the right hub assembly in stock but would have to order the left one.

Can someone please help me with the OEM part numbers for the right and left rear wheel bearing for an acura 2007 TL (3.2 Auto). I always thought it was the same part number for right and left. The part number I found when doing my research is: 42200-SDA-A51

Thanks
Acura TL 2007

 

Not saying rear wheel bearings never need replacement, but I'd make certain that they are bad before laying out the money. How many miles? Any rear tire wear?
L/R both the same number as far as I can see.

they are the same .. item 3 shows qty.2

 

I'm with Turbo, I find that hard to believe, especially coming from a dealer that can't even figure out the part # correctly...

Guessing the "roaring" noise is a cupped/worn tire and that you will find your alignment out of spec (rear toe specifically).
