2007 CHEVROLET AVALANCHE Suspension Problems

We are repair facility. on or about 5/2/2023 the vehicle was towed into our shop with the right front wheel bearing sheared off - the customer stated he did not have any impact/accident with the vehicle. We noted that the wheel bearing still rotated - no explanation on why the hub would shear off. At the time, we inspected the entire front suspension (with extra emphasis on the left front bearing/hub assembly) and found no deficiencies. On, or about 5/19/23 the vehicle was towed into the shop - the left front hub/wheel bearing assembly had sheared off. In 30+ years in business, we've never seen a hub shaft sheer - let alone 2 on the same vehicle

I HAD BEEN NOTICING THAT THERE WAS A SLIGHT NOISE ON THE RIGHT FRONT END OF MY 2007 AVALANCHE. I CHECKED THE UNDERCARRIAGE AND DIDN'T NOTICE ANYTHING WRONG. I HAD AN OIL CHANGE DONE AND IT CAME W/ A FREE TIRE ROTATION. THE SOUND SEEMED TO BE GONE AFTER THAT , I CAN'T BE SURE. THE TRUCK HAD APPROX. 12,000 MILES ON IT. I WAS GOING TO DROP OFF SOME PAPERS WITH A CUSTOMER ON OCT. 6TH WHEN I HEARD THE NOISE AGAIN. I WAS LOOKING FOR THE CUSTOMER'S TRACTOR THAT WE WERE REPAIRING IN THE FIELD AND WAS SLIGHTLY BOTHERED BY THE SUN SO I PUT ONE OF MY HANDS UP TO BLOCK THE SUN. WHEN I LOOKED BACK AT THE ROAD, I WAS IN THE WRONG LANE. I TRIED TO CORRECT AND THE VEHICLE ACCELERATED ON IT'S OWN! I APPLIED THE BRAKES BUT DIDN"T GET THE SAME RESPONSE...
