What is causing bad wheel bearing on one side

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Tundra. Repeated issues with a wheel bearing on one side, especially after an impact, can often be traced back to residual damage from the initial curb hit. Undetected issues like a slightly bent steering knuckle or axle housing, misalignment, or damaged suspension components can add stress to the new bearing, causing it to wear out prematurely. A cracked rim from the impact also indicates that the force might have extended beyond the wheel, affecting nearby components. It's worth having the suspension and alignment thoroughly inspected to ensure there aren't any slight distortions or misalignments still causing added stress on that side. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
