2008 Yaris Buzzing

[TLyttle]

Lots of money made by the "rebuilders" by taking a perfectly good alternator and replacing the bearings. It is the method they use to replace the bearings that assures a return customer!

I replace alternator bearings by pulling the old ones, then burnish the shaft so that the new ones slide on, not press on. Takes a bit of time, but the bearings will last far longer, and take less power to turn.
