1990 v1500 suburban. With the 350 5.7, 100k miles, all stock suspension(for now). Love the car and plan on keeping it for a long time just this sound has me stumped.

Doesn't happen every drive, it sounds like a card in a bicycles spokes until you come to a stop and you hear a slight clunk. Usually after the clunk it stops but not always. Sounds like it's coming from the passenger brake/suspension area. I've looked over the area and dont see anything noteworthy. Plenty of material left on brake pads. It runs and drives great.
Any ideas would be appreciated! Thank you!

 

Possible parking brake, did you check those pads?

 

not yet, I'll pull a drum tomorrow and have a look. Thank you!
