Hello. Good to see all the Patterson photos. Good to put faces to the names.
My coach (77 Palm Beach 403 53K miles) has begun to make a whining sound when under power. Take off and begin to notice it about 30 mph, increases slightly in pitch as speed increases, then is gone at ( or I just cant hear it any more) at cruising speed. Whining stops when I let off the throttle, then begins again when I give it gas. Also a slight whine when coming to a stop. Don't think it's bearings; have new ones and knuckles with zerks, which I maintain. My trans has a few minor leaks, the pan is clean, but don't know its service record. Fluid level is good. Had the coach about a year. Overall, coach is in good shape and well maintained,
Any ideas or links to study would be appreciated.
Thanks.
Roger
