Replacement of the front wheel bearings is done in accordance with the procedure
above for repacking the wheel bearings, except that new wheel bearings and a
new grease seal are installed.
Some notes -
Bearings and races come as matched sets — new bearings should NEVER be installed
on old races and vice versa.
Make sure that the numbers of the bearing parts match or that the new parts
are listed as acceptable replacements in the parts-interchange book at the
auto parts store.
If you are reusing the brake drum, you will have to remove the old bearing
races (inner and outer) from the hub and install new ones. Others have had
success driving the old races out of the hub with a brass drift, then tapping
the new ones in. Here’s what John Muir has to say -
It is possible to install the new outer race yourself. Clean the wheel hub
thoroughly. Hold the whole bearing up to the hub to make sure you know how
it goes, with the heavy part in, then get the outer race started in the hole
evenly all around. Use two hammers, one on the race and one to tap it with.
Tap this race into the hub until it is inside the hub, then tap it in with
a dull chisel until the race is seated on the shoulder of the hub. You can
tell by the solid sound when it’s seated. Now proceed to packing the bearings.

Personally, I find this a bit daunting. I prefer to take the hubs to a machine
shop to have the old races pressed out and the new ones pressed in.
With the new races in the hubs, proceed to pack the bearings, replace the
hubs, and adjust the bearings as above.
