Duster front drum wheel bearing R&R

Plenty of people have replaced just the bearings on the old races through the years and it's been just fine. I've done it myself. In the past. But, IMO, it's not the best idea. Steve is dead right. However, they are not matched when they are new......they are what I call "neutral". In other words, they have no wear pattern. The old bearings and races however, are matched to each other. It is best to replace bearings and races together. Some bearings and races are not available as a set, you you have to purchase separately. Most automotive bearings are available in sets, but there's always that exception. As easy as they are to change out, replace the races, too.
