Rear Axle Shaft Bearing NSK B35-188 with 35 mm Inner Diameter 74 mm Outer Diameter and 2RS Sealed Design for Toyota Probox Succeed

The rear axle shaft bearing with NSK part number B35-188 is a direct replacement for the factory-installed bearing in the rear axle of Toyota Probox and Succeed models. This bearing supports the rear axle shaft, ensuring smooth rotation and efficient transfer of load from the axle to the wheel. It is the exact cross-reference for the Toyota Genuine part number 04421-58010.

The bearing is a single-row ball bearing with a sealed (2RS) design, which keeps lubricant in and contaminants out—critical for a component that operates in the harsh environment of the rear axle housing. With an inner diameter of 35 mm, an outer diameter of 74 mm, and a dual-width profile of 17/26 mm, it fits precisely into the rear axle housing, supporting the axle shaft and allowing it to rotate freely. It is designed to absorb both radial and axial loads exerted by the vehicle during motion.

A failing rear axle shaft bearing typically reveals itself through a growling or humming noise from the rear of the vehicle that increases with speed, excessive play in the rear wheels, or vibration felt through the floor or seat. This replacement bearing restores smooth, quiet operation and ensures safe, reliable rear axle performance.

This NSK rear axle shaft bearing B35-188 directly replaces the factory component in the following Toyota models:

NSK is a world-leading bearing manufacturer and a trusted original equipment supplier to major automotive brands including Toyota. This bearing is manufactured to the same exacting standards as the original equipment, ensuring reliable performance and long service life.

The bearing features contact seals on both sides (2RS). This design keeps the factory-applied grease in place and prevents contaminants such as water, dirt, and road debris from entering the bearing. A sealed bearing requires no maintenance and delivers consistent performance over its entire service life.

With a 35 mm inner diameter, 74 mm outer diameter, and 17/26 mm stepped width, this bearing precisely matches the original Toyota specification. The stepped width design ensures correct fitment in the axle housing and proper alignment of the axle shaft.

This bearing is the direct cross-reference for the Toyota Genuine part 04421-58010. It is also listed under the aftermarket number B35-53F for the same application. When a customer searches by any of these numbers, this listing provides the correct replacement.

A worn rear axle bearing produces a characteristic growl or hum that increases with vehicle speed. Replacing a worn bearing with this NSK unit restores smooth, quiet operation and eliminates the vibration that can be felt through the floor or seat.

A failed bearing that continues to be used will eventually damage the axle shaft itself and the axle housing. Replacing the bearing at the first sign of noise prevents this cascading damage and avoids a costly axle rebuild.
