National 32209-A Axle Differential Bearing - Front or Rear

National 32209-A Axle Differential Bearing

The National 32209-A is an ISO metric taper bearing assembly built for axle and differential service where precise fit and consistent load handling matter. Manufactured with premium materials and engineered to OE specifications, it is a direct replacement choice for driveline repairs on applications such as Honda Civic and Toyota Corolla where the correct bearing dimensions are critical.

Detailed Description

National 32209-A is a taper bearing assembly designed for axle differential applications that require a 45 mm bore and an 85 mm outside diameter. The cone and cup dimensions are matched to support proper seating and alignment in the differential assembly, helping maintain smooth rotation and stable driveline operation. This part cross-references SKF BR32209 for the same application.

For repair work on Honda Civic and Toyota Corolla driveline systems, the National 32209-A provides the dimensional consistency needed when replacing a worn axle differential bearing. The OE-spec engineering focus makes it a practical choice for technicians and DIY owners who need a precise replacement bearing rather than a universal part.

What It Helps Fix

• Wheel or driveline noise traced to a worn differential bearing
• Excessive play in the axle or differential assembly
• Rough rotation caused by bearing wear or surface damage
• Vibration from improper bearing support in the driveline
• Noise after differential service when the original bearing is no longer serviceable

Installation Notes and Tips

Verify bore, outside diameter, width, and series match the original bearing before installation. Press-fit bearing replacement should be performed with the correct tools to avoid damaging the cone, cup, or mating surfaces. Clean and inspect the housing, shaft, and related components before assembly, and confirm proper preload or endplay settings according to the vehicle service procedure.

Quality Assurance

National manufactures this taper bearing assembly with premium materials and OE-spec engineering standards for dimensional accuracy and dependable driveline service.
