UPDATE: I sent Lippert a email about the parts that I was needing. They responded that they no longer made the sealed bearing system, and that no parts were available. The entire axle would need to be replaced... (The ruined spindle was gonna require that anyway). They were offering to sell those of us with the affected units axles at a BOGO price.
I called them, and told them that I really wanted to upgrade while I was at it. Long story short, I am retiring my 5200# axles and installing 7000# axles, springs and brakes. They let me have a very good deal. Especially as the TT is 6 years old now. I wasn't expecting any help.
I will miss the maintainence free aspect of the 5200s, but I figured that if they pulled them off of the market that fast, that there must have been a lot of problems with them. The Dexter system looks suspiciously like the same bearings... But I am leery now. If parts were to be needed on the road, it could be a major problem.
I am satisfied with the outcome of my "Lippert" experience thus far.
So long as the axles arrive as advertised, I would rate them an A+.
