Boost Junkie Member 8 Member For: 11y 9m 12d Gender: Male Location: Nowra Posted 20/07/14 09:23 AM Share Posted 20/07/14 09:23 AM I have a dull humming coming from what sounds like the gearbox. I originally thought it was the tailshaft center bearing so I replaced that and the center uni yesterday which did absolutely nothing. The noise sounds like a bearing is dry and dying, it doesn't go up and down with revs it only increases as the speed rises which is why I thought it was the center bearing. Any ideas what this could be? I'm going to check the the gearbox oil level tomorrow but there are no leaks anywhere, I'm getting worried cause it gets a little louder each week.
