3 needle-nose tool? for 6400/01? freehub
Attempting to break down the freehub.
After removing the axle and looking down the freehub, I can see the large ten ball bearings.
On the outside of here and slightly higher there is a ring shape with three small pinhole size holes spread like three points of a triangle.
RJ The Bike Guy has a freehub overhaul vid where he uses a homemade 2-hole tool to unwind a similar position ring.
Mine is definitely a 3-point/hole.
Any ideas what tool would be used for removal?

Are you looking at the dust cover? I think you just use a hex key and remove the fixing bolt. Then pull on the free hub body and it should be off.
Shimano FH-6400 or FH-6401? Or is this some other brand since you said it was 6400/01?
A pic will help us know what you are seeing.
Found the SI's..

If you're really inclined to disassemble the freehub you could make a tool like RJ but with 3 prongs.
