While driving home from Branson (232 miles total one way) I stopped for gas and two hubs were kind of hot (different axles) but touchable and two were cold. I took the camper yesterday to get the bearings checked. I just had them packed last year and I told the service writer that the technician may have tightened two of them down to tight. Since repacking last year I have only driven 1200 miles and I don't consider that excessive miles. I would assume while driving they should all be close to same temperature. 2007 Chevy 2500HD 6L Auto 4WD 2015 Keystone Outback 5th Wheel Wife and 2 great kids, Son-Army 45th Yellow Lab theoldwizard1 • View posts SE MI Senior Member Joined: 09/07/2010 View Profile Offline Posted: 07/29/20 06:37am Link  |  Quote  |  Print  |  Notify Moderator Warm (you can keep your hand on it) is acceptable. * This post was edited 07/29/20 06:52pm by theoldwizard1 * ksbowman • View posts Kansas Senior Member Joined: 08/22/2012 View Profile Offline Posted: 07/29/20 06:38am Link  |  Quote  |  Print  |  Notify Moderator Yes, they should be close although the side receiving the sun will be elevated. I use an infrared temp gun from Harbor Freight and it makes checking temps very easy. They are very reasonable there. Roger10378 • View posts Goodrich, MI.

You have just made a stop and if some brakes are tighter than others they will generate more heat. 2005 Cardinal 30TS 2007 Chevy 2500HD D/A lenr • View posts Indianapolis, IN Senior Member Joined: 04/12/2008 View Profile Posted: 07/29/20 07:20am Link  |  Quote  |  Print  |  Notify Moderator X2 on brake adjustment. I once adjusted my brakes after a break in period, and 200 miles down the road one hub was 50 degrees hotter than the other 3. Had the tool with me so laid under the trailer at the rest stop and loosened it slightly. Problem solved. ALKO axle support (back before being bought by Dexter) told me that hubs could run as high as 300 degrees without a problem, although that seems high to me.

I usually check bearings during stops cause my bladder is 2 hours or less range and typically they stay cool. please show picture of temp gun you use and is it accurate.

Yes, the sun side will run a little hotter, maybe 10-20 degrees. Lots of variables, including over tightened bearing, or brakes not all adjusted the same. The main thing is uniformity being reasonably close on all hubs. One 50 degrees or more warmer indicated a problem, that needs checking. btw, the term technician may not describe every guy, with a wrench in his hand.

If we’ve just completed a steep, long climb ( our 5er weighs 20 K) I’ll get a truck rear differential temperature! Most highways have a pretty good grade/angle to the curb/ditch side.....where the warm bearings on the “downhill” side. I generally get higher temperatures on the tires and bearings on the curb side ( on a 2 lane road). I assume that the weight transfer due to road angle puts additional load on the “downhill” side! memtb * This post was edited 07/29/20 07:53am by memtb * Todd & Marianne Miniature Schnauzer's - Sundai, Nellie & Maggie Mae 2007 Dodge Ram 3500, 6.7 Cummins, 6 speed manual, 3.73 ratio, 4x4 2004 Teton Grand Freedom, 39' 2007 Bigfoot 30MH26Sl BobsYourUncle • View posts Calgary Alberta Canada Senior Member Joined: 12/12/2003 View Profile Offline Posted: 07/29/20 07:53am Link  |  Quote  |  Print  |  Notify Moderator Another vote for the temp gun. I carry one at all times. So simple to point the laser beam at the hubs and read the screen. I use it on tires too, including my inner dually. 2007 GMC 3500 dually ext. cab 4X4 LBZ Dmax/Allison 2007 Pacific Coachworks Tango 306RLSS - 32' Reply to Topic  |  Subscribe  |  Print Topic  |  Post New Topic  |  Oldest first Newest first  Page of 6   Next Open Roads Forum  >  Fifth-Wheels  > Checking on Wheel Bearing Heat
