Power steering pumps don't break down? In my 1989 Raider, V6, 5sp, when I turn the steering all the way left or right, the idle becomes erratic (800-1200 rpm) and then the vehicle stalls when I step on the accelerator.

A growling sound comes from the front of the engine when I step on the accelerator and the sound becomes worse as the RPMs rise.

Is this not a bad power steering pump? The power steering gearbox looks pretty bad, too as the boot is torn and the gearbox leaks as evidenced by how covered it is in grease.
