The ATC4454 Rockwell Meritor Axle Seal Driver Kit is a professional-grade service tool set designed for the correct installation of Rockwell / Meritor axle seals. Engineered as an OEM-equivalent solution for R4422401 and R4422402, this kit ensures precise, damage-free installation of axle seals during axle service, hub removal, or differential repair procedures.
Proper axle seal installation is critical to preventing gear oil leaks, bearing contamination, and premature axle or hub failure. Improvised installation methods can distort seals, damage sealing lips, or install seals out of square—leading to costly rework and downtime. The ATC4454 kit provides purpose-built drivers that apply even, concentric force to the seal, ensuring correct depth and alignment every time.
Designed for durability and repeatable accuracy, the ATC4454 is ideal for heavy-duty truck service centers, fleet maintenance facilities, trailer repair shops, and professional driveline specialists servicing Meritor and Rockwell axles in on-highway, vocational, and off-highway applications.
