Operating Temperature for Hubs
Updated 05/20/2024 | Published 05/17/2024
Question:
Hello, I have a Hustler tandem axle trailer with surge brakes on 2 wheels. I believe it’s a Dexter. Recently when driving back about 30 mountain miles my hub temperature was 140 degrees on both wheels.The week before my temp was 115 degrees after a2.5 hours drive with some flat roads and some mountains. I haven’t had temperatures this high before. I don’t know if the safety brake cable was pulled or not. Brakes are not locked up. Should I be concerned about 140 degree temperature? The non brake hubs are under 100 degrees. Any suggestions would be greatly appreciated. Regards Chris

Hi Chris; the temperature you measured isn't anything out of the ordinary. Hubs running in the 140-175° range aren't uncommon. If your hubs start hitting the 200° mark you could have an issue with the bearings and grease or the spindle nut could be too tight. The difference between weeks could have been a difference in use or the outside temperature. You could jack it up if you want and spin the wheels to see if there is excess drag just for peace of mind. If you haven't repacked your bearings in over a year that would also be a good idea.

Thanks for your reply. I did pull my trailer out of the garage to do my annual bearing service to re grease. The wheels were dragging and I noticed the actuator was pushed in. I backed up the trailer a bit and went forward and the actuator pulled out and the wheels released and spun freely. The wheels never locked up when I was backing up the trailer I greased and lubricated the actuator thinking it might need some. Should I have anything looked at before I take my next trip? I live in a mountainous part of NC. Thanks Chris
