Hi, how do you fix the cap that covers the ball bearings on the front wheel?
I recently bought a used 1999 cannondale m400.
The only thing I see wrong with it at this time is the front wheel. There is a flat cover and isn't tight onto the hub that covers the ball bearings and I believe it's getting dirty inside there.
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.

It it's a rubber seal, it's probably decayed and you'll need a new one. Try a local shop.

Its steel. I'll try what you said but should I first clean out the bearings and then relube it? What do I use to relube the bearings? Will any heavy lubricant work like lithium grease perhapS?

The cone should hold this in place... ideally the cone should go through it and the sheild then jam on the smooth edge of the cone. If it is working lose the hole in the sheild (that the axel fits through) is probably worn, it should not fit over the cone... but jam on it. In short as the wheel turns, the axel, cone and sheild should not... the cup turns around the sheild.
Lithium grease is fine, but a marine grease is better.. it is more water resistant.

As for grease, buy a tube of Phil's grease or Park. It'll last for years. A tub of marine grease is okay but it will last for several lifetimes

If like me you relube every 6 weeks there is nothing wrong with Lithium Grease! It could even last longer!
But... use a real water resistant grease (like marine grease) and it will last ... um... a year even!
Anyway, as regards the bearing sheild. I fess up, I got the wrong end of the stick. I have never seen that type of sheild... all of my bikes have had the fixed sheild, but most of my bikes are cheap!
