Some ARB air locker applications require that you change the OE carrier bearings to a slightly different carrier bearing.
If a change in the carrier bearing is required, it will be noted in the install guide provided with the ARB differential locker which is also available upon request in PDF form and will be available for download from the products online listing shortly.
For a list of all the available bearings, vist: ARB Air Locking Differential Bearings
