SQUEAKING sound from driver side !!!!

Zeetah

its the left side, its annoying the holy ship outta me.

my windows were down, and i couldnt pin point it, i hear it at every single bump, even at slow speeds for speed bumps, makes it sound like a cheap car.. so embarrassing, i think ill have to get a friend drive my car in front of me or vice versa to find out where its coming from.

but my question is will that 10w30 stuff or w.e its called be suitable? i rather use that myself if i can, and instead of taking to a shop
