Bearing running hot

I can report today cruising at about 100km/hr for over 700km, the bearing stayed within 5 degrees of the other bearings on the trailer. There was even one point where there was one that was higher than it by a degree or so. I am confident it will make it the 2400km left.

I would check the drive shaft modular. Could be the wing nut chipped off the fly wheel causing the belt to get tangled with the power stearing motor housing.

Squirrel?

What are wheel simulators?

Fancy hub caps

I backed the nut off 1/6th a turn. You cannot turn 1/4 on a six sided nut.
I also put more grease in the hub.

After a few hundred km, the bearing temperature is now less than 5C than the others.

I could probably back it off another 1/6th turn.

Why wouldn't you just jack it up and adjust the wheel bearing correctly?

Because, I did not have a torque wrench to re torque the wheel bolts (yes, the trailer is that old.) I know that you spin the drum, not spin the wheel.

Sorry, time to get a torque wrench!
I would have disassembled that wheel and inspected the bearing, the bearing and /or the grease could be burned.

Every Spring before I set sail for the year, I clean, inspect and repack my bearings. The dealer charged $50 a wheel or $200 +tx in my case, but it takes just over an hour to do it all. I have found trouble before it started. Blown seal letting water in turning grease to mush and bearings starting to go. Been riding for 11 years this way never an issue. I once had a brake issue while traveling and that taught me to carry my own spare parts as they can be hard to find on the road. I carry two sets of bearings and spare breaks and magnet among other house hold items.

breaking down on the road is no fun and I try to prevent all that work in my driveway so i can enjoy the road.

I would pull inspect replace if needed and repack all of my bearings if I were you.

Happy Trails.

Having towed a trailer years ago that the bearing disintegrated on it and the wheel went into the ditch, I always check the hubs.

Glad you found your problem.

There is a lot of talk about tires and blowouts on here. But little about people checking their wheel bearings when on the road. I'm guilty as most I guess.

I've wanted to take my wheel simulators off and check bearings more frequently. Just the thought of taking them off and I get dirty looks from my other half.

When on road I do check tire temps, I wonder how much temp(heat) would transfer to tire indicating a tire or bearing problem? Having access without hub caps and temp gun would be easier to pin point problem of... is it the tire or bearing causing the high temps?
