Left ball joint failed so I decided to replace both at the same time.  While I didn't use the cheapest, I definitely didn't use the most expensive replacement, although it claimed to be OEM standards.  Was fine for 3 months but now getting the pop/click on both sides now, depending which way I'm turning, and it only happens when turning on any sort of slope or under braking.  Flat turns (i.e. from a stop) it doesn't happen, but when I'm turning to the right, I hear it from the left and vice-versa.  Steering alignment is perfect and I don't feel anything in the steering wheel.   
  
Did I purchase some junk ball joints, possibly over-torque them, or should I be looking at something else?  Selling soon and this could kill the deal after a test drive.
