The power steering fluid in my KZJ95 seemed to be leaking intermittently. I don't see any fluid on the ground, but the reservoir gets low and I have to refill it every once in a while. Seems to be worse when it's cold. Mechanic thinks it's a power steering pump issue, and the fluid is leaking into the engine. Does this seem legit? If so, any suggestions for replacement part number? If not, is there anything further I can do to diagnose?
