How do you know if your wheel bearings are installed correctly?

To determine if your wheel bearings are installed correctly, listen for any unusual noises such as grinding or humming while driving, which may indicate improper installation. Additionally, check for excessive play or movement in the wheel by shaking it; if there's noticeable lateral or vertical movement, the bearings may not be seated properly. Finally, inspect for any signs of leaking grease or wear after installation, as these can also indicate issues with the bearing fit.
