De wiper rear back motor

[Welshy_Pete]

The rear wiper motor just makes a noise now and does nothing. It would sometimes work then not work now nothing. So I think its time to de wiper rear back motor.

I can see whats holding the motor in place. But whats the best way to get the spindel spine out of the glass?

Also what the best bung to use one that doesn't leak or come out?

306 hdi

thanks
