PROBLEM DRIVES
The Belt is the Sympton.....NOT the Cause
What causes belt noise? Misalignments and Slippage cause belt noise.
PAGE 1 OF 3 - NEXT DODGE TRUCK - BELT CHIRP:
Some 2003 – 06 Ram pickups with the Cummins diesel engine may produce an irritating chirp from the accessory drive belt just as the engine is shut down. According to Dodge, the noise is caused by the drive belt slipping on the alternator pulley as the engine makes an abrupt stop. Replacing the alternator pulley with an upgraded unit with an overrunning clutch mechanism should eliminate this annoyance.

TOYOTA TRUCK - DRIVE BELT SQUEAL:
Owners of 2000 – 06 Tundra pickup trucks may complain of an annoying squealing sound coming from the front of the engine. According to Toyota, the noise is most obvious during cold engine start-up and is due to the serpentine drive belt slipping on the accessory pulleys. Installing a new design automatic belt tensioner with a revised a/c compressor mounting bracket should help eliminate the annoyance.

JEEP WRANGLER - BELT CHIRPING NOISE:
2002 – 05 Jeep Wranglers with a 2.4L engine many times experience a chirp like sound coming from the accessory drive belt. The sound may become more pronounced at higher engine speeds. Investigation may reveal accelerated accessory drive belt wear even though the belt is properly installed on all pulleys. The accessory drive belt chirp-like sound is most likely caused by the misalignment of the power steering pump pulley to the shaft of the power steering pump. The pulley may have been installed too far (over-installed) onto the pump shaft. The front surface of the power steering pump pulley hub should be flush with the end of the power steering pump shaft.
