Just put a new bearing in today and the hub spins but with a lot of drag. Is the right? I dont want to put everythig back togeather if I screwed something up. Is there a way to grease them before assambley?

It should spin smoothly, but not freely. The grease in the bearing keeps it from spinning easily by hand. As long as it isn't notchy or clunky or feels like it has sand in it, its fine.

 

Some manufacturers pre-pack the bearing with grease and some don't. Usually if the bearing needs to be packed there will be a note in the package, but not always.

More than likely if you got an open end bearing, it needs to be packed.

I usually buy rubber sealed bearings because it avoids having to re-pack and keeps dirt out of the bearing.

Everything worked out great. Thanks
