MH042039
Rear Differential Reduction Pinion Pilot Bearing
Mitsubishi FUSO®

The Rear Differential Reduction Pinion Pilot Bearing, with part number MH042039, is a vital component of the commercial truck's drivetrain system. This bearing is responsible for supporting the reduction pinion gear, which is a crucial part of the differential assembly. The reduction pinion gear is responsible for transmitting power from the driveshaft to the differential, which in turn transfers power to the wheels. Without the Rear Differential Reduction Pinion Pilot Bearing, the reduction pinion gear would not be able to rotate smoothly, leading to excessive wear and tear, and ultimately, failure of the differential assembly. This would result in the commercial truck being unable to move, leading to costly repairs and downtime. Therefore, it is essential to ensure that this bearing is in good condition and replaced as per the manufacturer's recommended service intervals to ensure the longevity and reliability of the drivetrain system.
