"On the road" hub replacement kit for Shorelandr trailer

Silly question, what do I aim the IR thermometer at? The rotor? The part of the hub that sticks out through the wheel? Thanks!

The irony of this discussion. My father tows his Lund Pro-V over to my place this past Tuesday. On the way, the bearing buddy fell off and he lost the bearing and pretty much trashed the hub.

The part of the hub sticking through the wheel will get hot as well. It's the housing the holds the bearings, races, and grease that surround the spindle that the hub rides on. So yes, any part of the barrel portion of the hub will get hot if it is low on grease or a bearing goes out.

His was low on grease, bearing failed, blew out the bearing and the races, and then blew the bearing buddy off on the trip due to heat expansion of what was left. When I pulled the hub off, the remainder of the bearings fell on the floor.

Don't let this scare you. If he had maintained his bearings, the hub may have never failed. And bearing buddies are a help, but sometimes you just gotta pull that hub and pack those bearings good.

Best of luck!

I was taking different readings on both brake and non-brake axles..
The wheel itself, the hub part that protrudes through where the bearing buddy is, the brake caliper.
I compared the temps between the non-brake and brake axles and port/starboard sides. I also used the "touch the hubs with my hands" approach. None of them were too hot to the touch.
I did pack them with grease prior to the trip and made sure there was enough room for expansion when the temps went up.
