a picture of my wheel without the decorative cover over the hub. I'm sorry I don't have a picture of what it looked like before I removed the decorative covers, but never intending to reuse them, I threw them away.
I thought I would offer this quick tip for everyone out there that likes to DIY. "destroy it yourself".
A long long time ago in a land far far away I started checking the wheel bearings on my trailer every time I stopped. When I pulled into a restaurant for lunch I would walk around the trailer and touch each of the wheel hubs to see if they were hot or warm, and I did the same thing when I would pull into a camp spot for the night, I didn't know if it was of any use but, it made me feel better.
Then one day I pulled into a crowded rest area on the interstate and parked next to a big rig. As I was walking around touching the hubs to check my bearings the truck driver got out, came over and virtually congratulated me for checking all my bearings. We talked for a while and he said he had been taught to do the same thing on big trucks, and if more people paid attention to their bearing temperatures there would be a whole lot less problems with RVs.
I took this tip to heart even though I've gotten high-tech with a handheld infrared temperature sensor, and almost always walk around and check my wheel hubs whenever I get out of the truck.
But with the Arctic Fox, and I would say a lot of other trailer brands, a decorative cover is placed over the wheel hub to make the area look pretty which interferes with the ability to get a meaningful temperature reading on the hub by touching it or using a temperature sensor.
The plastic decorative covers on my 27 – 5L Arctic Fox are held on by the wheel and you can't remove them in less you take the wheel off, which I did when I bought the Goodyear Marathon tires that are on it right now.
And yes I know they don't look as pretty as they did with the fancy covers, but I will trade looks for the ability to keep an eye on my bearings, and the increased ease of greasing my bearings any day. And I think anyone who's had bearing problems like I've had with other trailers will agree.
I removed the rubber plug so you can see the Zerk fitting for greasing the bearings. The decorative covers made that job a whole lot more difficult.
