Truly, my point is the 2nd spur gear...
In my opinion, dont use stock aluminium pillow ball for rear joint. The old steel one will holds your rear hub better coz it has longer thread.
Why is your point the 2nd spur gear? Do you mean the 1st speed gear, because it touched the drs arm?
Why use the steel balls? Did you rip out a thread?
