Good clip from Ky afield.
I have turbo lube hubs on my trailer. They are o-ring sealed with a clear outside sight cap. Inside they are filled with 90 weight gear lube. You can see the bearings and the oil level, also if any water has entered due to a failure. 4 years and I am still good. At one time Northern Supply and Overtons was seeing this replacement system.
