Trailer Wheel Bearing Issue

With that being said, I think mine is an issue with how my trailer is loaded. My dragster and related items favor the right side of my trailer. Not sure, but something like this may be part of your issue. Maybe the attitude of the trailer as it goes down the highway could be a problem. Does the trail tilt slightly downward in the front causing more weight to be put on that axle? The roads we travel on are not flat, maybe adding to your issues. This seems to be more of an issue with triple-axle trailers. It would be interesting if we could scale our trailers like we do our race cars. That would definitely tell something.

Loading is an interesting thought. When towing the front of the trailer is about an inch or a little more taller in the front than the rear on level ground.
The trailer has a five foot lower and upper cabinet on the road side and is loaded with tools etc. I then pull a golf cart alongside the cabinet all the way to the front.
I would think the golf cart weight would offset the tool box however, the tools may outweigh the cart.
I will try to redistribute some of the weight along with the new USA made bearings.

I appreciate all the comments some of which I had not considered.
Thanks again,

The axle is out of alignment and putting pressure on that bearing or the tire has a weird wear pattern putting pressure on the bearing.

I would think if the axle was out of alignment it would happen on both sides of the axle not just one side.

Could the axle be bent slightly? Someone mentioned load distribution. With a few minutes at a truck scale could you get left/right and axle load numbers?

Being a retired UPS mechanic and seeing my fair share of trl bearings ....going to Timken is a great move.
Then get you a temp gun... and after an hour or so of towing pull over , in a safe area of course .... shoot the temp of all tire tread surface and side wall and then shoot the hubs ... record all info and then analyze .... This can tell you a lot about your load placement and maybe where to move the load around to equalize temps and weight on each tire.
you can also test with an empty trailer to see the big picture !

Hope this helps !

I have a temp gun just never did shoot the bearings.
We stop every few hours of travel and I always just feel the tires and bearings caps with my hands. In the summer the tires are pretty hot to the touch but that was what I expected in the hot summer days running on the hot pavement.
When we go out next time I will have the temp gun in the cab with me and do just as you suggested.
It may be interesting when I look at the results as the high temps on our next trip should be close to 100 degrees in the afternoon.
This has to be one of the best places to ask questions as you get some very good suggestions and answers to issues with all the experience on the site.
Thanks to all.

I have looked at the axle pretty close and can find nothing.
The tire has no unusual wear pattern and looks no different than the other tires.
I may try to move the tire to another axle or move it to the spare.
The tires are almost 3 years old and will be changed out over the winter.
I always balance the tires so that should not be an issue either.
I have checked and looked and I am still at a loss to figure it out.
Same bearing twice now, it just makes no sense to me.
The loading on the road side with the tool cabinet and a generator has been the only thing I had not considered.
The trailer does have about 1500 lbs in tongue weight so the front axle is probably loaded heavier than the other two.
I hope the China bearing change to the USA made makes the difference.
Thanks for every ones suggestions.
I appreciate the help.

The tire would show some sort of abnormal wear if the axle was out of alignment. If the tire is wearing the tread fairly even and not featheredged across the tread it's good. Trailer loading definitely might be a factor. More weight on one wheel is possible....

The type and quality of grease made a huge difference for me years ago on a trailer I had. It was eating bearings and only had 3500lb axles on a 22' box trailer. It would routinely trash a bearing and I was not towing long distances. It got to the point that every trip I made to the track I jacked the trailer up with car unloaded to feel the bearings. I carried complete new sets with seals.

I started using synthetic waterproof grease and never had a failure again.
That was a fairly new product at the time and was far better than the usual stuff.

My present trailer has Nev-r-lube sealed bearing cartridges......I've replaced them once for no other reason than I felt better with new. I kept the old ones for spares......

Blown tires and burned up bearings on the road makes for a rough trip.....been there....

From looking on the internet at pictures of the bearing race I removed the last time it seems to look like one posted from a bearing cage failure.
I am not sure what would make a cage fail but the softer material the cage is made out of is imbedded and stuck to the outer race like was shown in the photo's.

I have been using Mobil 1 Synthetic wheel bearing grease.
Even after the failure the grease was still clean looking and still red except in the bearing are where it was hot and it was discolored there but did not smell burnt even though it was hot and smoking when I noticed the failure.

I am going to rebuild both hubs on the axle with new USA made Timken bearings, install new hubs on both sides, and new brake assemblies. I am also going to move the rear axle tires to the front axle and replace the one that has failed twice now with the spare tire.
I am at a loss on anything else to do.
Anyone else have other suggestions.
I will try most anything once.
Thanks
