Answer
Hello and thanks for the question...I'll try to help.
It is removed from the bottom. Remove the pitman arm. Then the dust shield. Then remove the C clip. Then start the vehicle and place a pan under the steering box and crank the steeting wheel to one side. The pressure in the box will force the fluid and seal out. Re center the wheel and install the seal, clip and additional dust shield.
Hope this helps,
Erik
