Squeeky bed spring sound

Lately i have been having a loud squeeking bed spring sound comming from the left front suspension.. It used to only seem to do it when it rains, but lately it does it when i hit bumps, turn, or when i just sit idle and turn the wheels. Seems to be getting louder and happening more often.. Any ideas ? Thanks

what suspension you using? stock, coilovers, etc...
have you taken a look under there yet?
I would start by checking your ball joints, and if you find out that is what you are hearing, FIX IT!!! You don't want it to happen to you.
