My reading turns up a bushing at the upper end of the driveshaft
where it passes through the exhaust adapter plate.
Driveshaft rubs on the bushing making the squeal at low rpms.
Supposed to be barely visible through a hole in the exhaust housing
when the engine is tilted all the way up and rotated to one side.
Spraying silicon lube onto the shaft and bushing is supposed to kill the noise.
