Better, more robust deck spindle?

I apparently screwed up the link. This is the link to the video. The person in the video pulls a sealed bearing from a spindle, pulls a seal, showing green grease. Then re-installs the seal, re-installs the bearing, pumps the spindle with red grease until it squirts out, then shows that red grease made its way past the seals. Are you guys saying that this video is wrong?

I agree that the bearings need to be repacked, for those spindles with grease fitting it comes out between the bearings and will offer some cooling of the bearings, also the bearing size plays a big part in longevity especially when mowing larger amounts of acerage.
