This selection of drivetrain components falls outside of typical differential and main gear sets, offering specialized parts for passenger car and commercial vehicle applications. Located within the differential assembly and related drivetrain linkages, these parts ensure proper gear mesh, lubrication, and secure component mounting. These are often supporting elements crucial for maintaining optimal power transfer and driveline longevity. Examples include specialized ZF gears like MPN 4466-362-007 and MPN 4466-362-156, alongside MAN components such as MPN 81.37501-5052, and seals like ZF MPN 4463-301-003. This category covers a range of housings, seals, spacers, and related hardware essential for complete differential servicing and repair.
