I recently took my 1990 Ford Taurus to a garage. Driving it is unpleasant, or more accurately, steering it. Something going on in the steering wheel. Odd internal movements. The garage said there were worn parts. They replaced the rack and pinion, both outer tie rod ends, the subframe bushings, and the subframe itself. Still has the same problems. But, the steering itself is stable. I do not understand this. I took it on the Interstate, got it up to 75mph. Removed my hands from the wheel and car continued travelling in a straight line requiring only very slight pressure at intervals to correct for small drift - and that was despite high wind gusts.
So, what is with the sensation in the steering wheel? It feels like it is jerking at intervals. No noise associated. End result is that I do steering correction that isn’t always needed.
What is going on? I don’t drive this car much, but it used to handle very nicely. Certainly got a big enough repair bill that didn’t seem to address the problem.
