Product Details
The Honda OEM Differential Ball Bearing is a genuine factory replacement designed to provide smooth differential rotation, precise support, and dependable performance in compatible Honda and Acura transmissions. Manufactured to Honda's original equipment specifications, this precision-engineered bearing features the NTN TMB208C bearing designation and is an excellent replacement for worn or damaged original differential bearings.
Commonly used in Honda B-Series manual transmissions found in vehicles such as the 1994–2001 Acura Integra LS/RS/GS, 1992–2000 Honda Civic, and 1997–2001 Honda CR-V, this genuine Honda bearing helps maintain proper differential operation and drivetrain reliability.
The differential is responsible for distributing power to the drive wheels while allowing them to rotate at different speeds during cornering. Its supporting bearings play a critical role in maintaining alignment, minimizing friction, and allowing smooth rotation under load.
Over time, differential bearings can develop wear from high mileage, contaminated transmission fluid, excessive drivetrain loads, or aggressive driving. A worn differential bearing may contribute to transmission whining, grinding noises, excessive vibration, or abnormal differential movement.
Whether you're rebuilding a B16 or B18 manual transmission, replacing a worn differential, installing a limited-slip differential, or preparing a Honda drivetrain for a performance build, this genuine Honda OEM Differential Ball Bearing provides the factory-quality construction needed for reliable operation.

Common Reasons for Replacement
- Differential bearings should be inspected whenever the transmission or differential assembly is disassembled for maintenance or rebuilding.
- Transmission whining or abnormal differential noise
- Grinding or rumbling noises during operation
- Excessive differential movement
- Rough or noisy bearing rotation
- Worn or damaged bearing races
- Pitting or deterioration of bearing surfaces
- Contaminated or insufficient transmission fluid
- High-mileage transmission rebuilding
- Differential replacement or upgrade
- Limited-slip differential installation
- B-Series transmission restoration
- Performance transmission assembly
- Replacing worn differential bearings helps restore proper differential support and may prevent additional damage to surrounding transmission components.
Installation Notes
- Proper installation is essential for maintaining correct differential alignment, bearing performance, and transmission operation.
- Before installation, inspect the differential housing, bearing seating surfaces, and transmission case for wear or damage.
- Confirm that the replacement bearing matches the original component and is correct for the specific transmission assembly.
- Use appropriate bearing removal and installation equipment to prevent damage to the bearing races, differential housing, or transmission case.
- Important: Apply installation force only to the appropriate bearing race according to the factory service procedure. Improper pressing techniques can damage a new bearing before the transmission is reassembled.
- When installing an aftermarket limited-slip differential, verify the manufacturer's bearing requirements and inspect the transmission's differential bearing clearances.
- Follow the Honda factory service manual for the correct bearing installation procedures, differential clearances, and transmission reassembly specifications.
- After reassembly, refill the transmission with the manufacturer-specified transmission fluid and verify proper operation.
Note:
- Includes one genuine Honda OEM Differential Ball Bearing (NTN TMB208C). Differential assemblies, limited-slip differentials, transmission gears, seals, and additional bearings are sold separately unless otherwise specified.
For Honda and Acura enthusiasts rebuilding a B-Series manual transmission, restoring a factory drivetrain, or installing a compatible limited-slip differential, this genuine Honda OEM Differential Ball Bearing delivers factory-quality construction, precise differential support, and dependable drivetrain performance.
