Evening all. I searched and searched and seem to have information that points both ways. ... I have a mercruiser alpha one gen 2. Thanks to service manual 14, seloc, and this forum, I changed my gimbal bearing, carrier oil seal, bellows and a few other things. In the interest of full information, I had to pull the gimbal bearing one time due to misalignment with the grease hole. I used a wrench type puller. Not a slide hammer. I got rolling torque right on my second try and put everything back together. We went on a camping trip this weekend and there is a high pitched whine the second I put it in gear. It is either absent or much quieter out of gear. I seem to have found two opinions. ... I screwed up the gimbal bearing or the ujoint bearings are bad. The whine does seem to get worse when turning side to side and there is a tiny sweet spot where it stops. Since I used a bearing driver, my only thought it that the puller, which pulls on the inner race, damaged the bearing when it came out. It looked and felt normal before I put it back in. Thoughts? Could this whine be caused if I actually got the rolling torque wrong? Or is it more likely that I screwed up the gimbal bearing? Going to take it all back apart tomorrow, any advice is appreciated for a head start!
