When installing an ARB air locker, you'll also be dealing with bearings—especially the carrier bearings and pinion bearings. Ensure that you have the correct bearings to match your axle model and gear setup. If you’re using a Dana 44-style differential, ARB may provide a
wheel bearing kit specific to that axle, or you might need to source bearings from a third-party supplier (Timken, SKF,
TBS, etc.) based on the exact axle configuration.
