We had a problem with the belt slipping, so got a spray can of belt dressing that took care of the problem.
I'd use a mechanic's stethoscope to listen to the bearings.We used to just use wd40 to temporarily silence the bad bearing to know which one it was but a course now that seems like it may harm the belt
I have a can of that too. But in my old age, I figure that if the belt is worn enough to squeal, it is worn enough to be replaced. Besides at 289,000 miles, a little preventive maintenance is a good idea.We had a problem with the belt slipping, so got a spray can of belt dressing that took care of the problem.
