Gday Billy
I think I mentioned it before that you can get new wheel seals with a steel sleeve ( like a speedy sleeve ) that fits over your hub shaft, just incase your seal surface is damaged. I only run grease in all 16 of my trailer hubs and have never had any problem.
Keep going Mate, you will win in the end.
Take Care

It’s a spindle issue not a hub issue unless your races are worn beyond spec . I am sure when you swapped bearings you installed new races .

If you ever run into leaking wheel seal again, try lucas hub oil. I was running synthetic gear all in the hubs of my trailer years ago and one of them leaked all the oil out overnight while I was parked. Apparently it wasn't leaking before. I parked because there was no mess except for the stream running straight down.
I cleaned that oil off, filled the hub with Lucas. Hub oil and drove the rest of the week with no leak until I got home and changed the wheel seal

For his latest caper
Hig is pushing paper
Sprayin’ water vapor
In his APU

His water is distilled
His invoices unbilled
On rates he’s gettin’ killed
Like antifreeze he’s blue

His brakes are saturated
Leaving him frustrated

Hig don’t stop we love you!

I hope that puts that hub problem to bed! Change out that water pump and you should be good to go and keep an eye on it!
I like the way you tarped the load! Nice job, Billy! Saddle up and roll out!

Bill, it's absolutely beautiful out here in central Oregon this week. The high is the low 70's. Let me know if you stop at Gordy's truckstop here in La Pine.  Mike

Billy   google PD 680 cleaning fluid that's what we used to remove grease, hydraulic fluid

IP closed in my hometown back in the late 90’s and it pretty much destroyed our little town.  Then Johns Manville closed, then the tire plant.  I think I parked around that IP once when I went down there.  Probably will have something from there going to IP around Vicksburg before long.

Good... MAN! Have a go HIGY😂.GLASGOW SCOTLAND 👍

Happy motoring to the Northwest.  I vote for grease on all your trailer wheels, but would pull them every year to check the bearings.  I had a whistling on my Pete that we couldn't narrow down for a month and finally found a pin hole leak in the air to air cooler.  Have you noticed a loss of some power?  Sometimes that what will show up with a leak.  Be safe, Bill

Water bottle test for head gasket issue. May be why you’re losing coolant. TRP coolant at Kw was under $60 for a case 50/50 mix.
Many have already covered wheel seal advice.
For anyone else wanting and using an APU, get one that doesn’t connect to tractor coolant system.

i buy the wheel seals that come with an inner ring to mount on the hub first, then i dont have to worry about any burrs the hub which is usually the main problem, might want to give them a try

You got to get the hubs and seals that the parts supplier sells you and get everything inspected by the garage. Some thing is out of speck.

The only fix on that trailer where it can stay an oil bath is Axle Doctor . Grease packing yearly is the cheep way out .

Always use Distilled water is better.  Flush it because it will mess up your Liners

Hey Bill good video, might want to put couple shut off valves in the heater hoses to close off the APU from the rest of the truck engine. So you don't leak the anti-freeze / water mixture out on the ground. Take care and safe travels

Nice video Mr higB hopefully that will fix your trailer problems and I hope you get your Apu solve I know it's stressful

with engine cold, soapy water spray the entire side of engine, start bubbles will show you the leak, on the trailer seal make sure the hubcap plug vent hole is open, if it is plugged the pressure will constantly blow the seal out no matter what lube you use,

Like done and watching❤❤❤

To make sure the noise is not coming from the belts just take them off, turn on the engine and rev it up for a couple of seconds with the a/c on an d with it off. Make sure your windows are down
