At first I thought the chirping noise was the TOB but it sounds like its one of the pulleys. It happens upon start up and varies a little with rpm and clutch pedal pressure, but soon disappears once the cars gets warmed up, then its completely gone. My question is, are there any common or regular problems with a particular pulley or aftermarket pulley bearing. If anyone has had a similar problem and solved it, please let me know. If it helps its an eaton steggy V with 2.93 uppper and 4# lower and idlers, all are billetflow. Any info would be appreciated.
