In answer to the question in the previous post, mine shakes the steering wheel pretty good. Jumps rapidly 1/4 inch each way. The really odd thing is I drove it 20 miles on the highway yesterday and no vibration. Today, I drove it again and immediately upon reaching 60 mph, the vibration is there. I think it is something in suspension or the new power steering pump. We'll see.
I'll bet it has something to do with steering pump.
Keep in mind that most cars have SPEED sensitive steering. They back off the power assist as you speed up.
I bet it can't decide to be off or on, kind of like the headlights
I wonder how hard/safe it would be to disable power steering, just a for a quick test. You might need some assist all the time though.
When it vibrates "at 60" as some people say, does it stop vibrating when you go well above that speed?
If it were tires and many other things it would get worse as you go faster.
