It ran and drove but the power steering was damn near nonexistent, and when it did work, it felt "notchy" like the OP describes (but probably more so.) We unhooked the return line from the P/S pump reservoir and stuck it in a bucket and ran the engine while pouring ATF in the reservoir and sawing the wheel back and forth. Did that until the fluid was nice and pink and then some for insurance, reconnected hoses, topped up and worked the wheel back and forth a couple more times with the engine running to get the air out. Worked fantastically after that!
Thanks for giving me hope that the PS fluid flush might fix my problem. I really don't have all the 'click click click' noise that some have experienced, nor a whining/humming sound coming from the steering column. Just an occasional 'gunk gunk' sound when turning the steering at a stop or very slow roll, ie, getting in and out of parking spots. It almost feel like there's a 'dead' spot when turning the wheel, but only for a split second and once that's passed, steering is normal again.......
