Rear axle help

[Daveputt]

I could use some help understanding and finding a replacement rear axle.
Mine is broken and at a mechanic far far away. Diagnosis is a broken axle, housing and hub.
The housing repair is $1500 not including parts and labor for the axle and hub.
I'm hoping I can find a salvage axle assembly but their is 1 catch.
This is the only one I'm aware of with the factory Mor/Ryde setup. Are there others that would be identical or do I need to find the exact model as mine?
Is the Mor/ryde a bolt on item I can salvage or something builtin to the housing?
It's a 86 Holiday Rambler Imperial 33'
Dana 80 5.13 1 ton P37 11" ring with Mor/Ryde 10 lug 19.5" wheel (70% sure on the last one!)
I spoke with one person at Arizona Salvage and they will look it up and get back to me. Tomorrow I have 12 other salvage places to call. 1 has the exact model I need, not sure of price or availability just yet. It would be great if anybody knew this axle is on a Pace Arrow or even Holiday Rambler Presidential.

I had a axle repaired about 14? Years ago on my tow truck.
Mine just happended to a be a Dana 80 with 10 lugs wheels (but they were 16's) and it was in a 89 Ford F450 Truck.
No way will you find a good replacement axle for $1500 with out a truckload of luck.
Mine sounds like it failed like yours, Wheel bearing fails, Takes out housing end, and drive axle to top it off.
The repair got mine back on the road the next day. It was worth it to me.
My bill was $900 for the Labor and new axle end stub, I was still out about another $300 for the shop labor + $100 axle shaft.
Remember these are 14 year old prices.

Since you'll be on the phone, try some of these RV salvage yards, they might have an exact replacement.

The problem with any used truck rear end is it probably has more miles and weight loading on it than 3 RVs. I had to get a new rear end on an International school bus and it took 3 of them until we found one that didn't whine worse than the original! Good luck hunting!

Just purchased an axle assembly from http://colawrvsalvage.com
Called 30 different places today. 25 aren't around anymore. Those that I could chat with didnt have the exact model. Colaw knew enough about these axles to find an equivalent. I think most P series chassis axles would work but couldn't confirm.
$1450 shipped from MO to Chicago. Hoping install won't be too bad and might be able to sell the differential to help offset the costs.
Found others on c-list for much less but they came from a F-250 and wasn't confident it was the exact same.
Fingers still crossed that it bolts in!

Sounds like the right one. I remember the GM 3500 HD trucks having a Dana 80 like my Ford.
NO F-250 Ever had a Dana 80 of any kind.
