  9. Remove the hub from the axle housing. Inspect all parts for damage or excessive wear. If the seal needs to be replaced, pry the seal out of the hub with an appropriate tool. The seal is installed by tapping it into the hub until it is firmly seated. If the bearing race(s) needs replacement, drive the race(s) from the hub using a brass drift. Use the brass drift to install the race(s). Drive the new race(s) into the hub until firmly seated.
