Hired help left tractor in gear and it rolled into pond. Submerged for 1/2 the day, we finally pulled it out of the water. Had to repair some electrical, starter, fluids drained & replaced. Hydraulic fluid is pouring from out of the front axle. Usually milky and thick, it will goop out the most when turning the tractor. Looks like it is coming from the steering box. Do I need to replace this component or are the seals just bad & needs to be rebuilt? What else do I need to do to get this tractor right again? It did have a small fluid leak before being in the pond, but worse now. Any suggestions would be greatly appreciated.
