I have a Bravo 3 with about 1000 hours. I just replaced the gimbal bearing recently. After about 15 minutes on the muffs, I started hearing a squeaking and rattling noise from the bell housing area or upper gear case. I removed the top gear cover, but could not see anything abnormal. Has anyone heard this?
