old staircase under my truck?

So, i have a noise when i'm slowing moving, specially in my driveway that is slightly a hill while i turn around. It sounds like a squeaky old staircase creaking under the truck. It is a normally thing to need to lube suspension or driveshaft, CVs or whatever? that's what it sounds like but ive never really heard anyone talk about doing that.

 

Springs need to be greased maybe?

Edit could be worn bushings in the ifs starting go..

 

I got that after I had some body work done. Turns out the shop didn't fit the bed EXACTLY back to where it was so there was some rubber from the bed rubbing against the cabin. Mine sounded like a heavy rubber against steel sound.

 

Is that a big deal? Expensive fix?

 

I don't feel like mine would be that. Even though after I bought the truck and took the pinstripe off I noticed it has had some at least paint work at the bed on the driver side. It just sounds more upfront.

 

Oh. And It also does it some times just driving a straight line. Not really flexing the body or suspension. Just more noticeable and. The truck is flexing
