Hub Temperature

This is where I put the laser,are you talking about the brake drum behind the rim that you are pointing the laser to? If that's what you mean that will be directly related to the amount of braking that you were in doing, if you're concerned about the bearing temps then you want to be where my finger is pointing I believe. If there is a difference from each axle it could be that the brakes are not adjusted properly. I'm no expert by any means but this is the way I learned to keep an eye on the temperatures. Of course most of that was putting my hand on each one and making sure was never hot to the touch, but now I have the laser to get a more accurate temp. Click image for larger version

Well not sure what's going on now, got home from camping and measured the hubs again thinking i could repeat hub temp inconsistencies, all 4 hubs measure at between 115-120 degrees after i parked.

Don't worry about these temperatures or the differences front to rear. Bearing temperature can easily vary due to load (unequal weight between axles or even how the clearance was set at oem), grease distribution, brake settings, the difference in airflow or even how the measurement itself is taken. The temperature levels you are measuring are not too extreme for the bearings, seals and grease used.
