So bummed...Power Steering is gushing fluid

As Redfish stated, unhook column shaft and make sure steering box shaft doesnt wiggle
side to side.
If not, replace the seal.
I have done this the way it sits without removing gearbox.
Drill small holes through seal on both sides of shaft.
Put screws in holes snug.
Grab screws or pryoutward with diagonalpliers or other to popout seal.
Install new seal tapping gently at first, then use same OD deepwell socket to
finish setting seal flush to gear case or where old one was.

(unless its leaking from case)
