What's the fascination with trailer bearings?
So I've seen many, many posts over the years about checking hubs with IR guns for excessive heat. I've even seen posts where people check their hubs every stop. :E
My question is why? I have never seen posts where they talk about checking their TV wheel hubs at every stop even though "most" use the exact same bearing type. (packable bearing) It's always the trailer for some reason. I've never seen anybody check their hubs on their trucks after driving around for a few hours. :h
I've owned over a dozen trailers in my life and have never had bearing problems. Ever. I check my bearings about every 7 to 10 years and have never found anything wrong with them. (Brakes are a different story and that is why I even check them that often)
I get checking often with boat trailer bearings. Especially boat trailers that go in salt water. Makes total sense that they can get contaminated with water and salt and they need to be checked often.
But TT bearings? It's a sealed system that see's no contamination. At least under normal conditions. Unless a seal is damaged the grease stays in there and works just fine year after year after year.
I guess it IR gun makers in business and that's a good thing in this economy I guess. :)
