    Quick Question.....My Warn Hubs on my 89 K5 are warm but not real hot after I drive it around for a while. Is this normal? They were installed correctly with the proper grease and the wheels rotate freely when warm/hot. All this is happening with hubs un-locked with normal driving........Thanks......Det45

    It sounds like heat induced from your brake rotors. I wouldn't worry too much about it.

    have you taken your hubs off lately????? The grease could've got containmenated and the bearings could be going to hell. I'd check it out quick.

    It's normal for the hubs to be warm to the touch after a long drive. If they're too hot to touch, then it's time to investigate what's going on. (Or quit leaving your foot resting on the brake pedal while driving!) [​IMG]

    Hrm? On evry car I have ever driven the lug nuts get really hot when it has been driven. Evry time you hit the brakes ALOT of heat is created. Since your hubs are connected to your roter they will get hot. If you drive for a long time or in stop and go traffic they will get too hot to hold your hand on for more than a couple of seconds. If you ask me... nothing to wory about.

    When all else fails... Check the blinker fluid.

    If you're on the brakes a lot then they'll certainly get hot. But if you're just out cruising they shouldn't be too hot to touch.

    Up on Pikes Peak they have a ranger hut in the middle of the road, about half way down, where they check your brake temperature. If they're too hot, they make you stop and let them cool off. Last summer I was coming down in the Suburban, following a minivan from one of the flat states. [​IMG] He had his brake lights on all the way down.

    When we got to the hut, the ranger pointed one of those infrared thermometers at his front wheel and made him park for a while. I asked what the temp had been on the minivan's brakes... Over 600 degrees F! Mine were 104. [​IMG]
