Re: Left turn whining noise
With what they charge for the lower control arms, you'd think they were made out of gold (about $450 a side, just for the parts). Dealerships do not carry replacement bushings.
If you go after market, you're looking at around $150 per side for the LCAs. You can also buy replacement bushings for ~$20. Lots of labour involved either way you go (including the particularly difficult to remove clevis bolt).
Upper control arms are a whole lot cheaper and easier to replace. Can't remember how much the parts where, but it was less than a couple of hours to do both sides taking my time.
To be honest though, the description of the sound your vehicle is making doesn't sound like worn out bushings to me. It sounds much more like the right wheel hub. I know you checked it for play, but it is possible that the hub will generate some noise before play is detectable using the grab and shake method. Bushings, control arms, etc., are all more likely to make clunks and pops than wawawa types of noises.
