Can air get trapped in the power steering system and is there an easy way to bleed it?
When the outside air temperature is warm/hot, I hear a ticking/clicking sound when I turn the steering wheel. It is more noticeable at slower speeds. Car has about 90,000 mi. Power steering fluid was low so I added fluid. Noise didn't go away. I lubricated steering joints, but didn't help. Noise is not present in morning when temperature is fairly cool.
