Dexter 8k axles, nev-r-lube bearings

I "had" never lubes on my 2009 5er. This past summer while heading out to Alberta, the left rear brake drum broke up and the only thing left was the part that held the wheel studs. When a repairman came to the 5er where we were in a campground in Edmonton, he found the bearing to be damaged. He tried to get a new drum and bearing but Lippert told him they didn't make parts for that axle anymore. So got rid of the never lubes and got 2 new Dexter axles with bearings that can be greased when needed. The summer before last, my repairman, here, was able to change out the never lubes and one fell apart in his hand. I have never liked having them because I could never grease them myself.
