Maybe not useful but interesting. While swapping summer wheels for winter ones, a balancing weight fell off the drum of our 2004 Toyota minivan. Someone suggested JB weld so I put the weight back on with that. The van had a nasty vibration, especially affecting the little table between the front seats. Sure enough, the weight had fallen off and was gone. I lived with the vibration all winter. Next summer I mig welded a piece of steel on that drum where the weight was. The vibration was much reduced but still there. I ended up buying a new drum. It had no balancing weights. And there was no vibration. I don't know what this says about Toyota vs the aftermarket maker. I guess the Toyota drum was badly made.
