M870A1 Rear Axle

[Mustangsud]

Does anyone know where I could find a rear trailer axle assembly? The part number is D22AX503-209. I'm not having much luck finding it by internet search. It's the rear axle of the 40 ton low boy M870A1.

I looked. I was never able to find one. Other than load king directly.

I looked at doing a 25k meritor axle since I've got 3. Cutting it to length and rewarding it and welding the lock strips on it. It's the same tube size however it would have bigger brakes and be hub pilot over dayton.

So you can get one from Load King? I'm really surprised they aren't more readily available since they were made by Spicer!

Its the same axle as an 403LF trailer.

Can you tell me what is wrong with your rear axle?

Apparently, the trailer was involved in an accident in the military. It looks like a vehicle hit the trailer right at the back axle. The rim and tire are toast for sure. We haven't pulled it all apart yet, but it looks like the axle housing is broken.

If it just took out the spindle then those can be cut off and a new one welded on. Axle housings can be welded. Or you can use a longer axle and cut it down and they tube spline it and weld it
