Right on. These things represent a substantial portion of our retirement nest egg so they certainly deserve to be cared for diligently. I invested in a good infra red gun way back with the first RV and use the thing at every stop, have caught problems a few times before they became serious.
These Nev-R-Lube hubs represent quite a design departure form the norm of smaller cone bearings at each end of the spindle. They are very large and opposed with preloading torque on the center line of the wheel. I lift each wheel slightly off the ground and do the Dexter recommended top to bottom play test every so often as well. Short of dismantling the things, that's all the manual calls for on a periodic basis. If I get an indication one of them is questionable, I'll probably do all four at once as it will have some good mileage under it's belt by then.
