Squeaking when turn Left

2003 Pontiac Grand Prix SE.
When I turn left, especially a hard left, there is a squeaking noise. I can't figure out where it is coming from and part of me thinks there is something rubbing that is making the noise. I t never happens when I take a right turn. Any ideas what to check first?

check your wheel bearing

I'm actually leaning towards a bad strut mount

run it thru some grass or bumps if it the strut mount you will hear it,it could have worn the plastic cushon below the spring
