That's good because they wont last long with the tiny bit of grease behind the seals. What's funnier is when they have a zerk and sealed bearing. You can pump it all you want and no grease is going to get by those seals. There is a reason why the factories use grease filled spindles. Grease lubricates, cools and allows contaminents to be forced out. They may last a while but no where near the factory original.
