Axle parts are essential components within a vehicle's drivetrain, specifically relating to the axles and shafts that transmit power from the transmission and differential to the wheels. These parts enable vehicle movement and are found in both front-wheel drive, rear-wheel drive, and all-wheel drive passenger cars and commercial vehicles. This category includes a range of components such as axle boots, axle nuts, lock washers, and related hardware necessary for axle assembly and maintenance. Maintaining axle integrity is crucial for efficient power transfer and overall vehicle safety. Examples of parts within this category include Febi axle bolts (MPN FEBI02497), MAN axle nuts (MPN 81307156152), and SACHS driveshaft flex discs (MPNs 3400700467, 3482000361, 3400127401). These parts ensure proper axle function and longevity.
