good to know.. never seen a sealed bearing on any heavy truck trailers.. they run in an heavy oil which explains the longevity for them.
have wondered why the RV trailer guys have not gone to the oil filled hubs vs grease. could be the speed of a large wheel vs a 15-17" wheel rotation speed. don't know just guessing.
with a good size truck and strong motor the wheel coming off might not be something you would feel like a smaller truck and motor..
the 7K axles will be nice addition to the trailer.
still trying to figure out what's the big hurry where you have to run 75 MPh... too fast to stop, mpg in the toilet etc.. c u down the road...

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+.
