2002 Sierra Denali slight chirp over bumps

This one baffles me.. Truck did it last summer and then around October the sound went away. It was gone all winter and now it's coming back again. WTF? The chirp is very random and seems to happen more on sharp bumps or dips in the road. I'm suspecting the driver side middle or rear. Thinking possibly the step bars... this one got me stumped.

You and that truck

hahaha

 

Yessir.

 

I'll track it down this weekend. Thinking it's a step bar or maybe rear leaf.. maybe a cab bushing.
