My seat squeak was getting bad. It would squeak while getting in/out, shifting my body any direction and while going over any imperfection in the road.
It's just very annoying and cheap sounding. I could even notice it even with the wind/road noise @50mph and the radio on 25.
It seems that replacing the broken spring clip takes care of the squeaking. Although, I'm positive that the squeaking will back in due time considering this has happened before and only a couple months ago.
