buy one of these..
FWD Front Wheel Bearing Adapters
you may need one of these also to pull the inner race off the hub ... or cut it off..
Bearing Separator and Puller Set
please verify that the wheel bearing seals fit properly on the inner CV joint shoulder and on the shoulder of the hub.
this is probably the best video i have seen on replacing front wheel bearings that are pressed into the knuckle.. and the hub pressed into that..
notice the benz in the video does not use any seals like the toyota versions i linked images to below.. splash from the other side of the car goes right into the bearings and wipes them out..
