At about 66,000 miles, I had a standard oil change and tire rotation performed at a Chevrolet dealership, just before a 1,000 mile trip. While traveling, I noticed my car was starting to make an interesting noise -- it sounded as if there was excessive road noise coming from my newly rotated tires. I assumed (this is what I get for assuming) it was just because my tires had just been rotated and that it would go away. I put the problem off hoping it would go away (yeah right) and about 4,000 miles later, my car started making an awful noise when driving (around 40mph it was the worst). When the car turned one direction, the NOISE was worse, and when it turned in the opposite direction, the noise seemed to subside. In addition to the noise, the car would VIBRATE really badly.

I took the car to get the tires replaced, but found out it was my hub bearing -- specifically the front left.

The Chevrolet dealership was prompt about getting the bearing changed. It took them all of three hours. The note on the invoice states: "inner bearing on the left front worn causing noise, these wheel bearings are two-row ball bearing and thus have inner and out bearing and races. When it is the inner bearing that fails, it can sound like the other side of the car has the bad bearing due to the weight transfer when turning"

Total cost was $466.95, but it was covered under the extended warranty so I only paid the $100 deductible.

I hope this helps anyone with the same concern.

high pitch noise

BOUGHT THE CAR FEB 2014, NEXT DAY I HAD TO TAKE IT BACK DUE TO LOUD NOISE FROM TIRES. THEY SAID IT WAS INSPECTED AND COULDN'T FIND NOTHING WRONG WITH IT. TOOK IT BACK HOME 2 DAYS LATER RETURNED IT AFTER HAVING 2 CERTIFIED MECH. TELL ME IT WAS THE WHEEL BEARINGS, THE DEALERSHIP SAID THERE WAS NOTHING WRONG WITH IT HAD TO CALL THEIR CORPERATE OFFICE AND TAKE IT TO ANOTHER TOWN TO BE CHECKED. AGAIN THEY HEARD THE NOISE BUT COUNLD NOT FIND WHAT WAS WRONG. THEY KEPT MY CAR FOR A WEEK AND GAVE ME A RENTAL CAR DURNING THE WEEK THEY SENT IT TO THE CHEVY DEALER IN WHICH THEY FOUND A LEAK IN ONE OF THE SEALS AND GURANTEED IT WAS FIXED. 2 MONTHS LATER I'M STILL DRIVING WITH THAT NOISE FROM THE WHEELS. THEIR EXPLANATION WAS CERTAIN CARS HAVE CERTAIN NOISES AND THIS MALIBU AND ANOTHER CAR WAS THE NORMAL NOISE THEY MAKE. THE FRONT OF THE CAR WOULD SLIGHTLY REAR TO THE LEFT UPON 40 MILES AN HR OR SO. I DECIDED TO LET IT RUN IT'S COURSE AND DOWN THE LINE IF SOMETHING WAS TO HAPPEN THEY WOULD BE LIABLE MIND YOU, I PURCHASED THIS VEHICLE FOR $18,000.
