Hi Ernie
front wheel bearings are very easy to change. I just did a set the other day.
You can either get the bearings at a local bearing shop or online. The link here has them for $1.59 each. The seal should be a 25-42-7 seal. Any bearing shop should be able to match them.

Or you can get the AllBallsRacing kit for $16.40 It will have 2 bushings and 2 seals..

As far as changing the bearings, GENTLY pry the seals out with a flat head screwdriver. Then insert a punch through the hub. with a little side pressure you should be able to displace the center spacer a bit. then work the punch around the entire bearing tapping gently..gently.. the bearing should work its way out slowly. When the bearing comes out the inner spacer will fall right out. then flip the wheel over and gently tap the other bearing out.
Installation is pretty much the reverse. If you have access to a Hydraulic press, it is very easy to install the bearings, if not, use a socket that is about the same size as the bearing and (again gently) tap the bearing in until it seats. Flip over, insert the center spacer, and repeat. Now press in the dust seals, and you are done.
If you have a propane torch, you can heat the hub. The aluminum hub will heat faster than the bearings making it easier to insert and install the bearings.
I like to put my bearings in the freezer over night before I install them then heat the hub to minimize the binding.
If you have any questions, email or PM me and I will give you a call.
