Very true. The first thing I did was check out how to use the EZ Lube hubs. I jacked up the trailer and, using a manual grease gun, pumped grease in while spinning the wheels, until fresh grease came out the front around the grease zerk. And that takes a lot of grease, which tells me they didn't put an overabundance of grease in those hubs.
I don't disassemble and repack the wheel bearings on the front of my car/truck every year, or two years, or three years. I've taken a couple apart to replace the brake rotors and on all of them the bearings were just fine. Heck, the newest vehicle I own is a 2004 Honda Silverwing, and I've not pulled the wheel bearings on any of them just to repack the bearings.
I do need to check brake linings/drums so I guess I'll find out how things look at that point. Just hope I don't have to eat crow. :)
