What This Center Bearing Does

A center bearing supports the driveshaft between the transmission and the differential.
Over time, the rubber carrier can crack or separate due to heat, stress, or age.
When that happens, the driveshaft loses stability and vibration increases.

The TDA CB210020 helps ensure:

• Smooth driveshaft rotation

• Reduced vibration at all speeds

• Less drivetrain noise

• Improved stability under load

• Longer life for U-joints and driveline components

Replacing a worn center bearing restores proper alignment and prevents further damage.

Common Symptoms of a Bad Center Bearing

If you notice any of these signs, the CB210020 may be the correct replacement:

• Vibration during acceleration

• Driveline shudder at low speeds

• Knocking or thumping noises

• Excessive play in the center of the driveshaft

• Cracked, loose, or separated rubber support

The TDA CB210020 3XSA solves these issues with a durable rubber cushion and precision-bearing design.

Compatibility

The TDA CB210020 Center Bearing fits many Class 7 and Class 8 trucks that use a 3XSA driveshaft support.

Typical applications include:

• Freightliner

• Kenworth

• Peterbilt

• Volvo

• Mack

• International

Always confirm by matching part number CB210020 or by verifying your driveshaft series.

Installation Details

Installation is simple and does not require special tools.
Steps include:

1. Support the driveshaft.

2. Remove U-joint straps or bolts.

3. Slide the old center bearing off the shaft.

4. Position the new CB210020 3XSA center bearing.

5. Re-assemble and torque hardware to spec.

A proper installation removes vibration immediately.
