At how many miles should I expect to change rear wheel bearings?

Hello, Wheel bearings can fail at any time, but longevity of a modern sealed wheel bearing should be between 75-125k miles. Some will last longer or shorter, but a 2006 year model vehicle is a prime candidate. Raise the vehicle from the ground and attempt to move the tire in and out at the top and bottom. If there is any play there, you likely have a bad wheel bearing.
