This afternoon, I got into my car after work, started it and heard a squealing noise after turning the steering to the left, the steering also began to judder a little as if there were intermittent losses of power. After a few wiggles back and forth it was fine but during the drive home, there is still an occasional faint hint of vagueness in the wheel that I never felt before. Does anyone have any idea what this could be? I should add that I hit a pretty big pothole 2 nights ago while driving home and checked everything since and it all seemed fine at the time.
