It saves a lot of wheel changing. I open them all up and pack them with grease though. What is in there from the factory is somewhat lacking, and they will last longer with more / better lubrication.

Good tip. I'll do the same. It may also help to quiet them down a bit. They do tend to have noisy gear boxes.
