Some 2006 Raider pickup trucks with 3.7L engines may emit an annoying chirping sound from the accessory drive belt area. According to Mitsubishi, the noise usually occurs when the vehicle is traveling slowly with the steering wheel at full lock (such as while parking), and is due to the drive belt slipping on the alternator pulley. Installing a new-design, improved alternator pulley with a built-in overrunning clutch, Part No. 05170529AA, should eliminate the slippage and chirping issues in short order.
