Quick Freehub compatability question

I've just been advised that an XT 770 freehub body is compatible with the Saint M810 maxle hub.
Can anyone (Nicklouse, I'm looking at you here
) confirm that?
If they are cross compatible, then it could save me a ton of money.
In case it's useful, the freehub has a 15mm allen key fitting.

Can't confirm it, but very possible as the XT uses an oversized alloy axle.0

shimano tech does give most cross compatability options. have a look."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Presume you mean M810, not XT770?0 -
Well, what I've got now, is a Saint M810 hub, with a broken freehub body - it's wobbly as hell.
I called the bike shop to check the price for a replacement, and the guy at the till said he suspected that an XT 770 freehub will fit. He wasn't totally certain, but was fairly sure, and asked me to call back in about an hour or so when their head mechanic was back in.
But, according to the shimano tech docs, the only freehub that is interchangeable with the M810 part, is the M815 unit.0 -
saint is a screw in body while the others have a screw in tube.

They are not even close to being interchangable. Just have a look at the parts diagrams below -

He believed that just not using the freehub body fixing bolt meant they'd be the same size, but now I realise...mister p wrote:They are not even close to being interchangable. Just have a look at the parts diagrams below -

Without that the Saint freehub has no threads, as Nick points out.
Can't believe I missed that.
Thanks guys.0 -
but if he wants to strip them down I bet the internals will fit. :twisted:"Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Old thread but some updated info on this.
Looks like Shimano changed part numbers.
810 & 815 have part number Y-3D4 98080

https://www.paul-lange.de/support/shimano/explosionszeichnungen_archiv/FH//FH-M815-2826.PDF
820, 825 & 828 have part number Y3TH98050
https://www.paul-lange.de/support/shimano/explosionszeichnungen_archiv/FH//FH-M820-3386.pdf

https://www.paul-lange.de/support/shimano/explosionszeichnungen_archiv/FH//FH-M828-3388.pdf
The 820, 825 & 828 list this as the same freehub body that's used on the 810 & 815.
The 828 lists it as the same freehub body that's used on the 788.
https://www.paul-lange.de/support/shimano/explosionszeichnungen_archiv/FH//FH-M788-3175.pdf
The 788 list this as a compatible freehub body with the 988.
The 988 has part number Y3DY98040

You can use the same freehub bodies on the 810, 815, 820, 825, 828, 788 & 988.
Freehub bodies with part numbers Y-3D4 98080, Y3TH98050 & Y3DY98040 are either the same or compatible.
