Freehub body bites the dust
Two questions:
1. How to disassemble Shimano freehub body (7-speed) without special tools?
2. Are they repairable or better to buy a new one and care less?
Freehub body idles from half to 1,5 revolutions.

Free hub bodies can be taken apart in much the same way that freewheels can be disassembled. It is a finicky job that I no longer have the patience for, since it often works out that the part cannot be salvaged.Probably better to replace unless you cannot find a replacement
I just have spare time and kinda bored.

Axle removed? a 10 mm hex wrench separates the freehub driver from the rest of the, hub with a tubular bolt
you can try soaking the driver in solvent to remove old stiff contaminated grease then immerse it in heavy oil (90 wt) to re lubricate it
or toss it in a bin and put another one of same 7 speed sort, New driver, on, .

It's been covered before. Icebike.org I think has a nice walk-through on "winterizing your freehub".
Think Kimmo has posted about it too.
You do need a kinda-sorta special tool to unscrew the bearing cup in the freehub body. I've used a file that fitted in the notches. Some have managed with a suitable piece of sheet metal. One guy ground down a cone wrench. Don't forget it's a left hand thread.

Problem with the taking apart route is that unless you have a same donor there are no replacement parts about. So if any damage is found... The good thing is that thousands (as in the hundreds of thousands likely) of these were made at one time. So searching through used piles of wheels might prove lucky. Andy.
