ARB Air Locker(TM) Shim Driver Set Part #0770004 – Professional Differential Service Tool for Installing and Servicing Shims

ARBs new Air Locker(TM) Shim Driver is a professional automotive differential service tool for installing/servicing common shim pre-loaded differentials. Insufficient carrier bearing pre-load can result in premature bearing failure and ring and pinion failure in all differentials, and possible oil/air leakage issues in an Air Locker(TM) differential. Most common Salisbury style axle assemblies(e.g., Dana Spicer model 44) require the pre-load shims to be tapped into place in order to achieve the required pre-load during set-up. Tapping shims into a tight space from a single point on the outside edge of the shim can cause damage to the shim and render it useless, resulting in extra cost and labor to the installation. As part of ARBs new Air Locker(TM) Tools range of differential service/installation equipment, ARBs Air Locker(TM) Shim Driver is comprised of 6 different sized steel profiles designed to evenly distribute the installation force (from tapping) around the outside edge of a differential shim as it is tapped into place in the assembly. This allows thinner shims to be inserted into tighter places than would be possible without the Shim Driver.
ARB Air Locker(TM) Shim Driver Set;

• Comes with a size range to suit most common carrier bearing shim diameters


• Reduces the risk of damaging carrier bearing shims as they are installed


• The set of drivers are joined together as a set for convenience


• Air Locker Shim Driver Set


• Zinc plated finish

The ARB Air Locker(TM) Shim Driver Set is an essential tool for automotive professionals working on Salisbury style axle assemblies, such as Dana Spicer model 44. Designed to facilitate precise installation of pre-loaded differential shims, this set helps ensure proper carrier bearing pre-load, which is critical for preventing premature bearing and ring and pinion failure. Proper shim installation reduces the risk of oil and air leakage in Air Locker(TM) differentials, enhancing overall differential performance and longevity. The set includes six different steel profiles, each tailored to suit most common carrier bearing shim diameters, providing versatility across various applications. The zinc-plated finish adds durability and corrosion resistance, making it suitable for demanding workshop environments. The unique design evenly distributes tapping force around the shim’s outer edge, minimizing damage and allowing thinner shims to be installed in tighter spaces where traditional methods might cause deformation or damage. This reduces installation errors, saves time, and prevents costly rework. The ARB Shim Driver is conveniently joined as a complete set, simplifying storage and handling for technicians. Its robust construction and thoughtful design make it an indispensable tool for differential service and installation, ensuring accurate preload adjustment and reliable operation of your differential assembly. Whether working on routine maintenance or complex differential setup, this tool enhances precision and efficiency, making it a valuable addition to any automotive workshop or professional mechanic’s toolkit.
