2011 Azera GLS stabilizer & low control ball joints, etc

What is your question?

I hear squeak sound under the front passenger side of the car. When I drive slowly, I hear little noises from the steering wheel too. I was told that two front stabilizer ball joints and six low control ball joints should be replaced. What would you think? I'd like have a second opinion. How much labor hours it would take and how much parts it would cost?
