I tried plugging the cap back inside but it won't stay. Does anyone know how to fix this problem on my own?
Do I need a new wheel or do I need a new hub?
Sorry I'm new to mountain biking and want to learn what I can so I don't have to take it to a bike shop. Thanks.
Is it a steel or rubber seal? If it's steel, try gently bending the edge of the cover outward so that it's a tighter fit. It won't need much. Then use a rubber mallet to put it back in place. Don't go caveman on it. You should just tap it into place.
It it's a rubber seal, it's probably decayed and you'll need a new one. Try a local shop.
