The hanger bearing on a Peterbilt 379 typically should have minimal play, generally no more than 1/8 inch of vertical movement. It's important to ensure that the bearing is properly aligned and secured to prevent excessive wear and vibration. Any noticeable play beyond this could indicate wear or damage, which may require inspection or replacement to maintain optimal performance. Regular maintenance checks are essential to ensure longevity and proper function of the drivetrain components.
