The inside diameter of 1.181 inches (30.00 mm) is the critical fitment spec for this bearing—this determines whether the bearing seats properly on your driveshaft. The bolt hole center-to-center measurement of 6.299 inches (160.00 mm) determines whether the bracket aligns with your vehicle’s chassis mounting points. The maximum outside diameter of 3.933 inches (99.90 mm) is also a key dimension to verify against your original bearing.

Product Features
- Direct OE replacement. This bearing matches BMW OE specifications 26121226731 and 26121229089 for E34, E36, E39, E46, and Z3 models.
- Precision bearing design. The center support bearing supports both sections of the driveshaft and allows it to shift under load. A bearing in the middle is suspended in rubber to absorb vibration.
- Driveline support. Supports the driveshaft to ensure stability and reduce vibration during high-speed rotation.
- Universal joint protection. Helps protect the universal joint and extend its service life.
- Vibration absorption. Reduces driveline vibration and noise, improving ride comfort.
- Durable construction. Built with high-quality elastomer and alloy metal to withstand intense undercar heat and vibration.
- Pre-lubricated sealed bearing. Resists the elements and minimizes driveshaft runout.
Installation Notes
- Verify fitment. Confirm this bearing matches your original bearing specifications before installation. Symptoms of a bad center support bearing include a thunk from the center of the car, especially when dipping in/out of the throttle.
- Check your vehicle configuration. This bearing is designed for BMW models with specific transmission and driveline configurations. Verify your specific model and drivetrain configuration before ordering.
- Verify the inside diameter. This bearing is designed for a 30mm (1.181″) bearing opening. If your vehicle has a different size, this part won’t fit.
- Check dimensions. Verify the outside diameter (99.9mm), width (13mm), and bolt hole center-to-center (160mm) against your original bearing before installation.
- Recommended replacement时机. A great time to replace the center bearing is during a clutch overhaul, short shift kit install, or any time the driveshaft is removed from the car.
