RIGHT WHEEL ASSEMBLY SLIPPED AT HIGHWAY SPEED, CAUSING MY VEHICLE TO LURCH TO THE RIGHT WITHOUT WARNING. ONLY BY MY FIRM GRIP ON THE STEERING WHEEL, DID I AVOID A LOSS OF CONTROL WHICH ALMOST CAUSED A CRASH. *AK PREMATURE WEAR OF THIS COMPONENT IS NOTED IN OTHER GENERAL MOTORS SUV'S (SPECIFICALLY DURANGOS). THE COST OF REPLACEMENT (1500) THE COSTS OF RENTAL CARS WHILE MY VEHICLE WAS UNDER REPAIR ( 400) ARE PART OF MY CLAIM......LUCKILY NO CRASH RESULTED FROM THIS FAILURE.
