Common Issues This Bearing Can Address

• Excessive driveline vibration from a worn center support bearing
• Noise from a rough or damaged bearing in the driveshaft support
• Driveline movement caused by bearing wear or looseness
• Reduced shaft stability during acceleration or cruising
• Service replacement for a bearing with the wrong inside diameter

Installation Notes and Tips

Verify the bearing inside diameter before ordering, since fitment is based on the 25 mm bearing size noted in the application data. Confirm the driveshaft support configuration and compare the old bearing dimensions to the National 105-CC: 25.000 mm bore, 47.000 mm outside diameter, and 12.000 mm width. For Mercedes-Benz E320, C240, C230, C220, 190E, 300E, and 260E applications, matching the bearing size is essential for proper installation.
