CAUTION

• For vehicles with ABS, be careful when handling the projection at the tip of the speed sensor so 

as not to damage it by striking against other parts.

• The front hub assembly should not be disassembled. When removing the front hub assembly, the 

wheel bearing inner race may be left at the spindle side. In this case, always replace the front hub 
assembly, otherwise the hub will damage the oil seal, causing oil leaks or excessive play.

Required Special Tools:

• MB990326: Preload Socket 

• MB990767: End Yoke Holder

• MB990998: Front Hub Remover and Installer 

• MB991897:Ball Joint Remover 

Post-installation Operation
