Do I need to replace the abs sencer wheel
Expert:  Dan replied 6 years ago.
Nope, just remove the axle shaft from the axle housing and that will allow you to remove and replace the axle seal. Be sure to clean the axle surface where the seal rides so it's a nice clean surface for the seal.
Customer: replied 6 years ago.
It says grand the wheel so just thorw it away the car dont need it or please explain
Expert:  Dan replied 6 years ago.
Those are all steps if the axle were to be replaced. Since you are replacing the axle seal all that you need to take from this info is the procedure to remove the axle shaft and install the axle shaft into the axle housing. Sorry I wasn't clearer about the details and procedures.
