This is about my '85 300TD.

My power steering pump had been leaking for a year or so. I'd turn at a stop and hear the groaning at each far range of steering. I saw the frothing in the reservoir in unison with the groaning.

This year, as I started driving the car again, the power steering had been offering no help, hard to turn at low speeds. Last week, I resealed the front and back of the pump, following Stretch's DIY thread.

Yet, the pump still seems unresponsive. Still hard to turn the steering wheel.

Any thoughts? I've never let the pump run dry, always kept a bottle of fluid in the car.
