For a couple of weeks now, I've been getting this annoying chirping noise ONLY while the braking and going over a bumpy surface (which is every road here in W. PA). I can't quite figure out where it's coming from. I want to say it sounds like it's coming from the rear of the car but I can't be certain. I haven't touched anything on my car in months so it's not related to any recent work. Does anyone have an idea what it might be?

 

Check your wheel bearings/hubs in the front. Your fronts are loaded more when breaking and the bearings will take more of a beating over bumps. (When they start to go bad, they sound like squeaking brakes.)

 

Thanks for the tip...I'll check it out!
