Is it really a freewheel and not a freehub? [1] A disc brake compatible
freewheel would be a rather rare bird, and freewheels in general have
only been OEM specified on rather inexpensive bicycles for the last
decade or more. If the cluster is 8, 9 or 10-speed, it is almost
certainly a freehub, since 8-speed freewheels were known for breaking
axles and soon discontinued, and 9 and 10 speed freewheels have not been
commercially made.

Early Streetmachines were 8 speed rears, mine's 5/6 years old or so and
is a 9.

Mine's 9 speed too.

I guess technically it is a freehub, judging from sheldon's article.
The article does say however that the ratchet can be replaced
separately, and I did see it separate from the wheel in the mechanic's
shop. There was a screw thread on it.
