2100x2193 230kb(If the image has failed to load, click on it to view large version) Description: With the outer race removed you will have more clearance for accessing the inner race.
2306x2338 205kb(If the image has failed to load, click on it to view large version) Description: The bore seat for the inner race has two opposing notches (arrow) for access to the back rim of the race.
2162x2158 231kb(If the image has failed to load, click on it to view large version) Description: Use your punch at the two notched points and tap out the inner race.
1966x1618 218kb(If the image has failed to load, click on it to view large version) Description: As the race approaches the end of the hub, tilt the hub for your final few taps on the race until it falls free.
2070x1963 231kb(If the image has failed to load, click on it to view large version) Description: With both races removed, clean the hub thoroughly again to remove all traces of old grease and debris from the bore seats.
2630x2370 225kb(If the image has failed to load, click on it to view large version) Description: The rebuild kit includes inner and outer bearings and the grease seal. The races are factory-matched to their corresponding roller cone assemblies, so keep the parts from the right and left side kits separated to avoid parts being inadvertently mixed.
2050x2201 229kb(If the image has failed to load, click on it to view large version) Description: Assembly begins with the new bearing races. It helps to seal them individually in plastic bags and leave them in the freezer for 30 minutes or more so their diameters will contract for easier insertion. Label the bags to ensure that the factory-matched races and cones are installed together.
2250x2463 236kb(If the image has failed to load, click on it to view large version) Description: It doesn’t matter which race you install first. Just remember when you install the inner race to set the hub on the wood block to avoid driving out the wheel studs. Select a bearing driver of appropriate size and tap each race until fully seated in its bore. Then clean the hub thoroughly again.
2314x2715 235kb(If the image has failed to load, click on it to view large version) Description: Opinions vary, but I like to butter the entire area between the races to form a reservoir of lube and to prevent the grease in the bearings from escaping into the hub and starving the bearings. Use a high-quality wheel bearing grease. The product I used is rated to resist liquefaction to 560⁰F.
2118x2079 220kb(If the image has failed to load, click on it to view large version) Description: If you have a bearing packer, pack the inner bearing with fresh grease. Or, do it by hand by “scraping” grease off your palm to force it into the bearing cage until it squeezes out around the rollers. Completely fill every recess with zero voids. You can’t put too much grease in the bearing.
3200x1871 230kb(If the image has failed to load, click on it to view large version) Description: Install the inner bearing, add a little more grease and smooth over any areas where you can see the rollers. Wipe a little grease on the inner ring of the seal and press it home in the hub. The center ridge of the seal will spring back out; just confirm the outer edge is seated flush all around.
3276x1557 211kb(If the image has failed to load, click on it to view large version) Description: The grease cap was scratched and the brake disc splash shield was showing signs of corrosion, so I cleaned those parts as well as the hub water shield and sprayed on a couple of coats of high-temp brake caliper black.
