I'm a bit confused. Did you replace the reservoir after the accident
or before.

If fluid is dripping from the steering rack as you describe then it is
possible that a seal is leaking. It may also have just dripped down
from the broken reservoir. It is also possible that the rack itself
may have been damaged in the accident.

At any rate the pump may also begin to make noises and eventually fail
if it was run with no lubricant for several days.

I would say you need to have a mechanic look the car over.
