Unsafe/Cheap Wheel Bearings Front and Back of Car, I was noticing some Noise as i was driving, which sounded like the front Passenger Wheel(Bearings), as i went to take it off Lugs broke off..One By One, Then I paid and got that taken care of at Pep Boys because my warranty didnt cover fixing it, so as im driving out of Pep boys i hear the same sound coming from the back wheels as well, im thinking this is still a New Car but has Wheel Bearing Problems.... I havn't taken care of them as of yet, but if Wheel bearing break your Tire comes off...I Never heard of bearings only Lasting 50,000 Miles. My last Toyota was original and had 266000 miles and my neice is still driving today.. So if you hear Noise while riding, take it to Your Mechanic and have bearings Inspected.
