Broken Freehub
I was climbing a steep hill on my mtn bike yesterday when I heard a snap, thats usually bad. I found that the freehub would now spin independently from the hub. I removed the axel and found that there was no internal bolt to remove the freehub body on this hub. The model is a Shimano LX Paralax, I think its an older hub as I bought the wheel from someone. Looks to me like I got to get a hub and rebuild the wheel.

Nope. After you remove the bearings, cones and axle, stick a 10mm allen wrench in where the axle goes and it'll allow you to remove the freehub body. Stick a new one on and you're good-to-go.
That's one of the things that I like best about Shimano.

Yeah, I've done that before, but did Shimano ever make a hub that didn't have removeable bodies, because When I stuck the 10mm in there weren't any splines for it to catch.

OK I looked at the Hub closely and did see splines, But the 10mm was too big, a 9 fit and removed the body. I found that the threads it was screwing into were actually an insert which has broken loose. Repairing this hub looks pretty hopeless.

If you have a bike to ride and you're looking for a project, scan your neighborhood on trash pick up day. It shouldn't take very long to find a trashed rear bicycle wheel. Take your time and be picky until you find one with a Shimano freehub - it'll show up trust me. The flange diameter and spacing on almost all Shimano hubs are the same so you might even be able to reuse the same spokes for a zero cost repair.
Been there, done that.

Actually the flange diameter and spacing on some other hubs are also the same as Shimano. I've "upgraded" a couple of wheels that had Maillard and Sansin freewheel hubs to Shimano freehubs using Shimano hubs rescued from my LBS's trashed wheel discard pile. I relaced them using the old wheel's rim and spokes and everything fit perfectly.
