It’s about time for an update. I added a Wits’ End rear accessory panel yesterday. Thank you @NLXTACY for a great product. I still need to get everything working that I had hidden inside on my make shift bracket. So far I got my fridge and solar working which I needed for this weekend.
Wife had a work outing out at our river property so no time to finish. The 80 was the pack mule for her coworkers that couldn’t get their cars out to camp.
It was also the first joint journey of the 80 and 40 together due to me having to head back to normal life tomorrow.
Texas is now perfect camping weather.

DYN - You can wired a 12v outlet to the load side of the Morningstar to be able to plug stuff in and find a quick answer to what it draws and help fill in some of the unused area.:)

Nice. I have always wondered how/what to use the load side for. Ideas always flow when I access the beer fridge, the easy way. :)

Time for maintenance. I’m giving myself all this month to get a bunch done. This weekend was pulling the rear hubs for new bearings,steels, hub studs, and a coat of Por15. Also took the opportunity to swap diff drain and fill plugs to the modern era.
Next weekend will be heading to the front to replace inner axle seals, knuckles studs, and bearings if needed. They should be good since I replaced everything 30K ago.
After the axles are good I’ll be pulling the Inti rack for paint and new hardware. The Venezuelan powder coat is looking shoddy along with the nuts and bolts.

Was this your first time in the rear hubs and were the axle seals bad and leaking to the bearings?

Yes first time in the rear. Nothing was leaking to the outside but there was oil in the hub and not enough grease. Judging by the Timkin bearings I pulled out it was done at some point by the PO. The bearings looked good enough to go back in but I’m replacing them with brand new Koyo bearings. I would have guessed the bearings would have been burned to hell from lack of grease. I routinely touch the hubs on long drives to check for overheating but nothing ever seemed odd.
Axle splines looked good. No twisting due to locker or heavy foot with the Cummins.

I cant remember seeing a set with grease in place is why I ask. Im sure you know but if you didnt 98% of full float axles use gear oil to lube the wheel bearings. Good to know on the spline condition with all your torque. Are you going to mod the splines while out?

Toyota does not call for gear oil in a rear FF set up. Grease only.

Don’t care what shrubbery you all are smoking in AZ.

I should but I have had a spare set sitting in the garage waiting on that mods as well. It’s just one of those things I never get to.

Good to know. That was my thinking as well.

Missed the obvious point, drinking bong water again or is it the gummy bears.:flipoff2: The point was not to worry if the axle seals were leaking most do as it would not be a problem as the rest of the world gets by with oil.

Still illegal in AZ

well when I rebuild my rear end i left the small shaft seal out and did not grease the rear bearings. this will allow axle oil to get to the bearings like most full floaters out there. the inner seals were toast on mine hand hand oil grease mixture in both (not as bad as a front end can get but it was there) I made the call so the same lube is through out the rear.

just my $.02

Interesting. I haven't seen one of these oiled hub FF axles but all I have messed with are Toyota and a FF Sterling on my F350. One thing I did like on the Sterling was instead of a seal it uses an O-ring on the axle shaft to seal the oil out of the hub.

The only O-ring I remember on any Ford 10.25"/10.50" axles is the one that seals the full-float shaft flange to the hub (which is a great design.) I have not seen one with an inner oil seal or O-ring, which means they were oil-bath bearings. I think the newest one I have worked on was a 2004 10.50" from an Excursion I owned. It is certainly possible that the newer ones use seals and greased bearings though. What year is your F350 axle?

O ring is on the outward side of the axle shaft keeping oil out of the hub just like the inner axle seal from Toyota. I could be way wrong as I find my memory of things from last year not so great anymore. I guess I can only hold so much info and need to push old info out of my brain.
 
Well this turning the clocks back really sucks. My after work sessions are almost not even worth it now.
Anyway I got the driver side rear hub on.
@LandCruiserPhil I did use grease.:) Still using Mobile XHP 222 blue stuff on the bearings. I still find it a bit more tacky than the regular mobile 1 red stuff. Less breakdown in the hot months.

Thinking back really early 14bolt chevy are a majority of my experience. Have had modern dodge and ford with 1/4 million miles and never have opened the rear end on any of them.

Had lots of FF apart small to big and Toyota FF are the only axle that I have seen designed to use grease to lube the bearing. Im not saying its good or bad just Mr T is different.
