Denny, I think at 35,000 miles these bearings seem OK. I have taken each wheel off, bearings are tight and no excessive grease loss. I'm having a machinist make me a bushing to drive them out with a press. I know this won't be available on the side of the road, but at least I have a new bearing and will have the tool to install them.
I wonder about heat sensors that could be placed on the drums, and ideas? Or maybe a gun to read the temps. I took the stainless steel covers off the wheels so at least I can feel the hubs directly.
Let me have your thoughts, maybe we can all help each other!!!!!

Having a bushing made to install new bearings may be a good idea but it will not work to remove the old ones because of the lip that's the stop for the bearing. You have to push on the inner race to remove them. I don't know of any sensor that can be installed on the drums, I just use my hand and feel the lug nuts when we stop but be aware that it varies depending of how hard the brakes have been used.

Denny, I should have been a little clearer. The bushing will only be used to remove the old bearing. I will either use an old bearing or a slightly larger bushing to install new bearing.
By the way, the axle nut is 32 mm if you have metric tools. I have a large inventory of metric tools, and found that is the size in metric. It is a very tight fit though. I always use 145 ft lbs of torque to reinstall the spindle nut. I take each wheel off every spring before we get the fifth wheel out. The big snap ring takes a really big snap ring tool, but I have it also. I guess that's why I'm about "tool poor".

I have a 1 7/16 socket that fits it, to push them out we just used a piece of round stock and one of the old bearings to put the new ones in.

Use an inexpensive IR temp gun from Harbor Freight to check hubs at rest stops.
Accuracy may not be the best, but repeatability from measurement to measurement is excellent. Since you are really looking for one hub running hotter than the others, this is what you need.

Dexter warranty
Dexter's warranty says 100K or 5 years
Warranty is different from expected service life!

These are 42 mm and hadn't "failed" as far as the Dexter bearing wobble check - but were on the way with grease leaks. My fix - $800 bucks worth of new Easy-Lube axles:

Harbor Freight, that's a good idea, never thought of them. You're right, a difference in heat from one bearing to another would be quite revealing. If you checked all of them quickly each time you stop you would soon know about what readings you normally see, and anything out of that range, very far, would sure get your attention.
I'll get one next time I go to Wichita, thanks for the tip!!!
Denny, the guy is just going to make me something out of round stock on his lathe, and probably will use the old bearing for install. This guy is retired and just likes to goof with his lathe. Nothing real fancy. I was hoping a bottle jack (10 ton) that I use for jacking up the 5th wheel and truck could be used to press the old bearing out and in if a roadside emergency happens. However it sounds like it takes a much bigger press to do the job.

Assuming it's your trailer, all you need to do is pop the wheel cover off and you will see Nevr-Lube stamped on the hub dust cap. If they are Ezy-Lube, the dust cap will have a rubber plug you remove to insert a Zerk gun in to grease. If you have the 'old', disassemble and grease, a plain dust cap.
