If you don't remove the dust seal from the new bearings and pack them with grease you are waisting your time.the new bearings come with very little to no grease at all.
I would grab the top of your tire and see if it pushes in and out every couple oil changes. Once a year jack it up, remove tire, and spin the hub by hand making sure it it nice and smooth. Bearing should last for some time but in my case they have not. I would say at least every other year, pull off the hub and check by hand to make sure they are good. Only takes a couple minutes and you can clean all your brakes at the same time.
I ordered them as a nice kit from Rocky Mountain. I did this video a while back. I have been having so many issues with aftermarket parts that are made in China, I am switching to OEM for all my critical parts. These have not failed, but will continue to monitor every race.
