I just did those bearings and the dust shields were originally installed at the factory when bearings were unsealed. Now that all bearings are sealed the dust shield is no longer needed. My uprights still had the factory bearings along the dust shields when we disassembled them. The dust shields were promptly thrown in the trash along with the old bearings.
