AW Wagner steering pump vibration

[pr2501]

Hello

I am writing here because I would like to inform me about vibrations and noise coming out from the bump while steering when boat is sailing in harder conditions and turning wheel faster and stronger.

Noise and vibrations are present only steering starboard direction.

And for the therm harder conditions I mean 15-20 knots of wind with 2-3 meter big waves.

And I could notice leak on front seal.

What is wrong with the pump?

Is it that my pump can quit and I can lose steering at once?
