bird sounds under my truck
 

When I hit I the throttle and press the brake in it sounds like birds are chirping under my truck any ideas

possable brakes going out

Check your u-joints. You may have to drop your driveshaft to check them if you can't feel any movement in them. U-joints will start to chirp when they are seizing up.
