Steering servo centering in HPI Efirestorm Flux

[sumitro]

I am new to RC and need help with centering the steering servo in my EFirestorm Flux. The trim setting is not enuf.
i am not able to remove the servo ie. the ball head from the ball stud connecting the servo arm to the servo rod.
Can someone guide me how to remove the ball head from servo arm and free the servo so that I can center the servo.
i couldnot find any Firestorm specific video on this.
Appreciate if someone can guide me.

Regards,

Reset your trim to center. Leave truck and radio turned on. Remove screw from center of servo horn adjust horn and replace screw.

Thanks for the input.
But I am stuck with removing the servo horn.
Theres some kind of ball and socket link which links the servo to the steering part.
Am unable to remove the ball joint wihtout which I cannot access the servo screw.

Pull up on it. It should pop off, and then you can pop it back on with a pair of pliers.
