The other day I started noticing that when the steering wheel would return to center after a turn it had a very noticeable "notchy" feel to it. I un-screwed the p/s cap and the lid blew off of it. What's causing air to get into the system. Hydro-booster maybe
? This morning, same thing, notchy feel in the wheel, cap blew off again, and then steers smooth as butter again. Anyone else run into this before?
