My TT is going on six years old. I do not know about the previous owner but I have put over 20,000 miles on it in the three years I have owned it. Until I decided to replace the brakes it was lubed though the EZ lube zerks once a year.
When I did pulled the drums the bearings were well lubed. I cleaned, hand packed, then EZ lubed them. I like the idea of having the axles shaft filled with grease.
I have been told you can over pack them but the manual said to spin when wheel and watch for grease at the front bearing while pumping. It worked for me.
