Check casting number! Please check casting number of the old hub! Should have 1090-471-010 stamp on it. Checking this on parts list number/serial code in ZF SDM may result in wrong hub! **IMPORTANT INFORMATION** Due to a product modification of ZF, the hub itself is no longer supplied. Instead of this, the transmission needs to be updated to a modified standard. For that modification more items than just the hub need replacing. Following parts will be supplied with the new modified hub: - 8HP45.HUB03 (which is the modified E-Clutch hub and has stamp 1101-471-030) - 8HP45.SH01 (main/input shaft) - 8HP45.SUN03 (sun gear RS3 & ring gear RS2) - 8HP50.HUB02 (C-Clutch hub)
