| Remove and replace the differential assembly. Refer to the Dissasembly and Assembly Manual, RENR6454, for the complete procedure. The front differential is removed as per instructions for the rear, but does not have a transfer box attatched to it. The 908 Wheel Loader will require the brakes to be bled after assembly. Refer to Testing and Adjusting Manual, RENR6456, "Brake System Air - Purge". All machines covered under this service letter program have front limited slip differentials, so 0.5L 1U-9891 Oil Additive should be added. Before filling the axle check the instructions detailed in the Operation and Maintenance Manual, SEBU7208.For refil capacities |
