Steering is too responsive

My daughter drove it around the neighborhood and if a cop saw her, we would have been stopped for a DUI check. My wife also had the same thing driving the car.
I drive it the most and have gotten use to it.

Here's the thing. This might or might not be a power steering problem

It could be alignment

It could be something broken/ loose

It could be the TIRES

It could be a mismatch between the front and rear tires.

With the car stopped, engine idling, does the steering wheel "want" to take off on it's own? Does it try to do that if you rotate the wheel a little left or right? If so, definately a PS box problem, and might only need alignment of the control valve, procedure is in all the shop manuals.

But if it seems to "dart" left / right going down a straight road, there are a number of things could be the problem, as above.

I can remember two cases of simple tire mismatch

Back in the mid 70's I was "a little poor." I rounded up some bias ply recap snow tires on the back of my RR, with radials on the front. I only intended it for a second car, slow speeds, around town. At 35 mph, that thing was just plain scary. Felt like one end of the car was gonna waltz right off the road!!

The second was my then boss had a new (couple years old) 80s Dodge 1/2T. Rear tires were getting thin, so he had me put two new ones on the rear. Still all 4 radials, but different brands. At 45--55 mph that thing felt like it was going to swap ends. We finally went back and had the same tires put on front as the rear.

I would get somebody who KNOWS front ends and this generally does NOT mean a "big box" brand to look the thing over critically for play in the front end.
