 | Hiya, 
 Liqualube hubs have had great reviews.  Not very hard to do.  It is just a matter of removing your existing hub and seal, cleaning everything up really well, then it is a matter of drilling 4 holes in the hub (soft metal so you can do it, but would recommend a drill press when you do it) to mount the cap.
 
 The nice thing with liqualube hubs is if there is water intrusion, the fluid absorbs the water up to a certain amount and you are still protected from rust, etc.
 
 I'm looking to do it after I add disc brakes on my trailer.  They run cooler, and maintenance is a snap.  Change the fluid and you are done unless there are issues with leaky seals.  As long as the seals are good, I don't believe you have to replace them every time, but I am sure that as preventative maintenance you would after a couple of years of use just to be safe.
 
 Definitely a bit nicer than having to repack yearly...
