With regards to the aftermarket bearing hub....I too looked on Rock Auto and found that the hubs with sensors were relatively close in price to the Lexus OEM ($300). I saw a Moog with the sensor in the mid $200 range and preferred to go with OEM. Since I am not doing the work myself, I did not want to take any chance that the aftermarket hub would not be compatable with the sensor and cause the ABS light to come on. We all know what it would be like to pay for labor twice when you use your own parts. Right now I cannot hear any noise unless I'm on the highway but knowing how **** I am with my cars, I'm sure it will be addressed in the not so distant future.
