what could the cause of a power steering leak be
the rubber hoses cinch into a threaded connector, stresses increase at this intersection of hose and crimped metal threaded end. The leakage failures usually increase at this intersection.
True, and that applies to both ends, the pump and the other end at the steering box. Also, the reservoir on the pump could be cracked, you didn't say where the leak is tk777 ..some cars have a restricting device to prevent over steering at high speeds the hoses run through that too and that device itself can leak
The cause would depend on where it is leaking. There's a pump on top. There's a pair of rubber hoses. There's a steering rack with shaft seals at both ends. Everything gets old and hydraulic fluid pressure finds a way out.
