Which freehub tool?

My mountain bike developed a rubbing noise from the rear hub when coasting. I removed the cassette to check out the bearings (sealed cartridge). Both outer bearings seem to be good so I'd like to remove the freehub to check it out as well as the internal bearings. I don't have the tool for freehub so when I looked for it on the Park Tool site I only found one remover that has two notches (FR-2). The problem is that the site indicates it's for notches that are about 25mm apart, mine measured out at 29mm. Park also mentions the FR-2 is for older Suntour freewheels.

The bike is a 2013 Specialized Stumpjumper with Roval wheels and Specialized hubs, nothing fancy. Any idea what tool will fit these notches?

Those notches are to disassemble the freehub. not remove it. What brand/model is the wheel hub?

The usual method to clean and lube a freehub body, loose ball Shimano type, is to remove it from the hub shell and soak it in a solvent. Blow out the old and solvent and dribble in fresh medium weight oil. Most people don't take that type of FH body apart. That's what the two notched part will do on a Shimano type, open up the bearing and ratchet internals. No reason why you shouldn't if you have the tool but since there's no replacement parts typically available and the resulting clean and lube is about of the same grade as the soak, blow and dribble in method why bother.

Shimano use to offer a tool for the removal of the ball race (two notched part), I've used one before. Whether it would also fit your hub is any one's guess. Finding said tool outside of an older and service focused shop is unlikely. Have you contacted Specialized/Roval? Might be good to know options and costs before doing something that might not work out. Andy

I think these are the Shimano tools (or similar). Rumors are that people have also made them by trimming down old sockets..

Since the cassette lockring size is standardized dictating the size, there is a good chance that the tool will work, or could be made to work with minor modifications.

YOu can make a tool should you choose to get into the freehub internals. I've also seen where they use a piece of flat stock steel modified to fit.

It's a Specialized Hi Lo disc hub. The freewheel has SRAM splines, but I probably can't confirm the brand/model until I remove it and see what's stamped on the back. I thought the notches were for removal. I took off both endcaps (they have tiny allen set screws and the axle came loose but won't slide out, seems to be hitting something inside the freehub (I assume an internal bearing). Can't figure out how the free hub comes off.

If it can't be serviced, I don't mind replacing it if only I could figure out how to get the thing removed.

Looks like the freehub is removed with a 14mm allen from the ND side, and disassembled with a tool ground from a socket,

but taking apart the freehub may not be necessary for you.

Thanks for all of the help. Turns out I needed to tap out the bearing cartridge on the ND side with the end of the actual axle (as it only comes out through the ND side). Then you can unscrew the FH with a 12mm allen. Loosening it is a whole feat in itself. Seems as though there was a bit of grit between the cartridge and the end caps that was making all of that noise. Cleaned it up and all seems fine. Will take it out for a test spin today or tomorrow.

I've attached an exploded view below. ND side is on the left. Note there are no threads on this type of axle.
