I will probably try to replace the 2 front drum bearings first since the edges are almost worn out on them. I have a pair on the truck but they don't have rivets so I will take 4 with me and the gun. They have metal pieces that go through the hole then you just bend the tabs over to hold them in. I don't really like that design too much and think rivets are better. I will hold off on the rollers in effort of trying to save the customer some money. Customer stated they replaced about 1 year ago and even the black carbon washers looked new and not very brittle so I have to believe they probably were replaced. This rubbing noise was so loud that over the phone we knew they had a dryer problem when they first called us even before they said what it was. Haha.
