Anyone replace a rear wheel bearing?
I'm trying to replace a rear Wheel bearing and not sure how to press it in correctly. I bought a new one from Malloy, fucked it up trying to press it in. Now I need to to press it out and replace but want to do it correctly. I searched for links but came up with nothing. Anyone got a link?Thanks in advance

I have just done 3 in the last month or so. Best tips I can come up with:
Use a pulley removal tool with good bite on the ends to remove the inner race from the spindle once you have removed the spindle. I used a small plate over the end of the spindle to have the pulley removal screw push against. You also may or may not need to use a large hose clamp to keep the hooked ends around the remainder of the inner race as you try to pull it off. Also may need to heat the inner race (limiting heat to the shaft) a bit to loosen it on the spindle shaft then try to pull it off. Extra hands are a big help.
To put the bearing in the hub put the aluminum hub in the oven to ~250-300 degrees for 10 min or so. put the bearing in the freezer for a couple hours. Very quickly remove the hub from the oven (use mitts) and then drop the bearing into the hub assembly, just as you get it out of the freezer. It will likely slide in with no pressing necessary. (worked on 2 of mine, 1 needed a bit of a push). This will minimize the chance that you damage the bearing on install. Make sure you reinstall the large c-clip before the next step!
Finally to press in the spindle you can freeze the spindle, and heat the hub & bearing to only ~100. Then brace the opposite side of the inner race as you press in the spindle from the other side. This will get you the most stress free install. Good luck.
