what happened here was a robot malfunction that over torqued the wheel bearings on a group of f53 ford MH chassis...

my luck was that I got two of them...
the first was a 2015 ford chassis fr3... it sat for weeks try'n to get parts..

we bought the motorhome,headed south on vacation...went 60 miles and the wheel bearing was dust

gonna say it was mid 2014 chassis...but I did notice that the lack of grease in the bearings to be an issues that I would have checked on all f53's
easy to do and might save you from roadside camping for 9 hrs....

I have this new F53 and mine is fine. I spoke to a friend at the Ford dealership and he says that he has no knowledge of this chassis with systemic bearing issues.

However, that said, this chap does show the bearing removed, later in his blog. I see evidence of flaking on most of the roller and heavy smearing on one (mind you he only show the outer bearing and not the medial one). That would suggest that the bearing was preloaded too much resulting in excessive axial loading or it was not greased, or both. He also says that he checked the right side bearing and it was not greased even though he had been driving it for hundreds of miles and it still spun freely.

I too am a bit skeptical.

Cheers
Scotty
nothing wrong with skeptical...
I own an auto repair shop,...

when they delivered the fr3, the front brakes were smoking...I acused the delivery guy of towing a car with it.. it said he didn't...but I was skeptical
so ,... anyway.. I drive it to get gas..."feels like it has a bad wheel bearing or tire problem" I tell my wife...
I had another set of tires at the shop, have my guy swap them...
seems to have got better.. so we head out...

we went about 60miles...and again tell my wife... something is way bad here, feels like the wheel is gonna fall off....

so I get to the side of the road..lift it up on the levelers...you could pull the top of the tire a good 10"..

I thought they never tight'n the lugs....took the cap off,... all good

took the bearing cap off....dust.... the rollers were complete gone!!!

Did a lot of bearings at the gas station in HS days and never had any issue like this....but we knew what we were doing.

Bearing causing loss of that amount of MPG would be glowing as therr is an abundance of power and rolling mass so the friction would need to be great.

I call BUNK...

Stuck caliper maybe...
lol

I call it two chassis with bad bearings...

steve and sue topped off the tank of their new 2015 Itasca tribute and hit the road...they drove exactly 100 miles and stopped to get gas...the tank took 25 gals to top off... what was Steve and Sue's mpg???

And if there was a system failure the castle nut will not be so tight that a pair of channel locks cannot remove it. I don't want to call anyone aliar, but this is pushing the limits of belief.
I took a video of me try to bust the castle nut loose with channel locks..
calling people names for trying to help another fellow MH owner is un called for..
the motor home is the second one for me...with the problem..ford says it was the failure of the robot and that's why the thing failed...
there was so many failures that they depleted the stock of spindles and hub assembles...
I was able, with the help from greg at the cheetah boats dealership in havasu..to back off the bearing and save the hub and spindle

Mike Thompson tolled him that there were so many failures parts were on back order.

He does own a repair car repair facility and has been around mechanical things all his life. At one time owned and drove is own alcohol dragster.

The second all most failure was on this new rig.

I posted this to make sure if anyone had a new Ford Class A to make sure and check you rig. Hope this helps outl
hey buddy... thanks for the post...and the fr3 was also a 2015

It did seem like you were just trying to help.
If I had a Ford chassis I would have appreciated it.

thanks for the kinds words...
hopefully will get some good miles out of the Winnie... we had a 2013 26 he winnabago before the fr3 and this one... we tow a 24' box with 2 rzr xp1000's , or the boat everywhere so the smaller coach works great for me
