Wheel bearings again!

A year ago I lost two bearings (nearly at the same time) after extended travel (about 6 hours straight) in hot weather. Both axles were replaced with 6,000 lb. axles (upgraded from 4,000 #).

Last week, while traveling in extended hot weather, I lost another bearing. Each time I stop, I always feel the hubs for any heat build up. Nothing, until now. I pulled in to fuel up and checked my bearings. Found one smoking. Pulled away from the fuel line and the hub immediately broke and the wheel nearly fell off. What am I doing wrong? I do tend to drive a little fast (around 65-67 MPH), but not excessive.

I KNOW the axles were properly lubricated on both occasions (prior to failure). This recent bearing/axle has less than 3,000 miles on it, and is less than 1 year old.

What causes this?

    thank you. I am so frustrated right now...and skittish about towing.
    Don't worry. Once you have new bearings and they are installed correctly, you should have years of towing ahead. I have the original hubs on a '72, that's 41 years, if my math is right.:)

    As long as I have been building trailers, I haven't gone through that many bearings. Are you packing them? If so, how tight are you setting the nut? That is probably the issue.


    I had them professionally installed by a trailer company (unfortunately over a thousand miles from where I am right now!). I did not pack them myself, they were new less than a year ago and less than 3000 miles ago!

  • That is beyond abnormal and has to be something being or not being done…

    Bearing adjustment, wrong bearings, wrong lubricant???
