I had to put on my tire cables today up on the mountain, and while I was driving (under 30 mph of course) I got an intermittent chirping sound from my front right side, even when I was barely moving. It mostly went away after I took the chains off, but then it moved to the left side later. I looked to see if the chains were rubbing, and I think they were occasionally grazing the bottom strut receiver, but didn't even rub the paint off.
Any ideas what this is? The struts are only a couple of years old, and don't have that many miles on them. Do bad sway bar bushings chirp like a bird intermittently? I looked, and they are still attached, but I have no idea how old they are.
Inexpensive problems are preferred
