The ARB Air Locker Shim Driver (0770004) is a professional-grade differential service tool engineered for the precise installation and servicing of shim-preloaded differentials. Maintaining correct carrier bearing preload is critical; insufficient preload leads to premature bearing wear and ring and pinion failure. This tool is specifically designed for Salisbury-style axle assemblies, such as the Dana Spicer Model 44, which require shims to be tapped into place to achieve specific tolerances.

Tapping a shim from a single point can easily deform or ruin the shim. This driver set utilizes six distinct steel profiles designed to distribute installation force evenly around the outside edge of the shim. This allows thinner shims to be seated in tight housings without damage, ensuring a reliable setup for both factory and Air Locker equipped differentials.

• Six different steel profiles sized to suit common carrier bearing shim diameters
• Evenly distributes force to prevent shim deformation and damage
• Zinc-plated finish for long-term corrosion resistance
• Drivers are joined as a single set for convenience and shop organization
• Essential for Dana 44 and other shim-preloaded axle assemblies
• Manufacturer Part Number: 0770004

The ARB 0770003 Air Locker Differential Case Spreader is an essential specialty tool for technicians installing or servicing Salisbury-style and shim-adjusted Banjo-style axle assemblies. Achieving precise carrier bearing pre-load is critical to the longevity of any differential; this spreader allows you to safely and controllably stretch the housing casting (the "pumpkin") to insert necessary shims according to OEM specifications.

By utilizing the factory spreader sockets in the housing, this tool eliminates the guesswork and risk of damage associated with improper installation. Ensuring correct pre-load prevents common failures, including premature bearing wear, ring and pinion damage, and potential air leakage in Air Locker systems. Built for professional shop environments, it provides a highly effective solution for heavy-duty axle maintenance.

• Precise Pre-Loading: Safely stretches axle housings for accurate shim placement without risking permanent deformation.
• Universal Compatibility: Pre-drilled hole pattern is designed to fit most common axle types, including Dana Spicer Model 44 and other Salisbury assemblies.
• Durable Construction: Manufactured to withstand high-force applications; includes a powder-coated parts tray for organization.
