ARB Differential Carrier Shim Installation Drivers

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 differential. ARB differential carrier shim installation drivers are professional service tools for installing/servicing common shim pre-loaded differentials. Most common Salisbury-style axle assemblies require the pre-load shims to be tapped into place 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, rendering it useless, resulting in extra cost and labor. ARB's shim drivers are comprised of six different sized steel profiles designed to evenly distribute the installation force around the outside edge of a differential shim as it is tapped into place, allowing thinner shims to be inserted into tighter places than would otherwise be possible.
