It really depends on how "deep" you
go into the hub assembly, you can do
a quick pull it apart, clean and regrease
the splines, but little dissassembly, or you
could pick every last piece apart and forget
how to put them back together.
The hardest part is the springs, there is a
way they need to go in to work right, I would
leave those alone unless they are all full of
junk, and even then only if they won't move right
Other than that, what you need to do is pull the
outer allen heads off, slide the knob and guts out,
clean the rust and dirt, lightly lube and put together,
little or no parts need to come apart, then you could
do them again when you have the time, and or someone
who has done them before and get them good and clean
