How smart are you ?

Hi again,

This was the thing I wanted to ask you about, when I struck on the
keyboard trouble.

Okay, here it goes. I am working on a car that has to pass inspection
by the department of motor vehicles, and I have had to do a lot of work
on it. On this ( a Mazda ) I had to remove the drive shafts, in order to
replace a brake disc, and I also had to replace a worn out rubber
gaiter for the constant velocity joint.

This thing would not come off, so I had to cut it, - and I have to
replace it.

The constant velocity joint:

Inside it is riding on 6 steel balls. These are secured in groves in
the body. Does any one know how the make these ?
I just can't understand how they do it. In a ball bearing, I would
guess that if all the balls was placed tight together, you would be able
to get the outer and inner rings together, with the balls inside. Then
you evenly place the balls, and secure them with the guide rings. But
on these joints, there is no space other than the groves, - you can't
move the balls around anywhere. So how is it possible to manufacture
such things ?

This is the puzzle, any one knows ?

( sorry about my mechanical terms, - it is not always easy to express
your self )
