Original Honda front wheel bearings are ball bearing with a single sealing cover on the out side of each bearing. Most folks pull the half shaft along with the steering knuckle and A arm and take them to a front end shop to have the bearings pressed out. The new bearings ( Front wheel
bearing requires 2 each side #6305) and will be sealed (seals on both sides) No grease necessary on these. (The originals will need about a pint of grease between the bearings) Remember to remove the dust seals with care as these can be reused if not damaged. Clean everything and don't lose the spacer between the bearings, this is necessary to hold the bearings apart when bolting things back together.
Caution, the bearing seat in the housing on many knuckles is worn and not allowing the bearing to seat. (this is normally the reason they need to be changed out) There are bearing retaining compounds that will lock the bearings in place. The problem is getting the bearing centered in the knuckle before the compound sets. Locktite has a range of products to accomplish this and most are available off the shelf. However once again getting the bearing centered is the chore.
What you can do is cause the inner area of the opening to increase in size by using a sharpened (to a point) nail punch and make a series of indentations or dimples in the metal inside surface area where the bearing seats. Since the bearing seat is about a quarter inch below the outer edge of the knuckle bearing housing you should keep the dimples in this area and about four across making the same number on both sides in an X configuration to keep the number of indentations or dimples the same on all sides. Use a retaining compound like Locktite #620, it's high temperature (400 F)
h igh viscosity liquid. Sets in 30 Minutes at room temperature. It provides a shear strength of 3,000 psi on steel. Use a bearing tool tap the bearings in place. Remember, lots of dimples will give a better surface to center the bearing.
Pulling the axle back through the bearings can be hard. But you should be able to get a few threads to show and then by using the castle nut and washer (s), larger nuts even the box end of larger wrenches will work to give some added space to work the shaft through and seat it against the cover of the dust seal in the inside of the assembly.
Also, remember this is not the front bearings on a Chevy, the Castle nut should be torque to about 150 pounds feet. (or as tight as you can get it) No backing the nut off here. It really needs to be tight. If the holes don't line up for the pin, make it tighter then put the pin in.
