Squeaky Pig drivin me crazy now

[Slik69]

Prior to buying my truck, it sat outside in the elements/dirt/heat for 7 long years. It ran good when I first started driving it, but almost like everything else I've had to EVENTUALLY REPLACE due to rust from sitting.. after the recent rains I've noticed now that since it has gotten wet underneath the truck has turned into a noisy POS. I mean it squeaks like crazy. Some of it front end.. some of it rear. What parts can be replaced to get rid of this noise. I have never heard this til now. I'm thinking after it being driven in the rain.. and now dry again, all the suspension parts are...

I mean this thing squeaks even at a slow rolling stop. It's kind of annoying and embarrasing now because you hear it before you see it. I'm not sure what parts need to be changed, but something. Could it be the shocks. They are new, but maybe they need some oil?? Don't know.

Sounds as if the brakes are squeaking too. Will it do this is the drums are thin with new lining. I was told I needed new drums a while back. I say this because I sometimes hear this squeek (maybe all the time) from the wheels/brakes??
