My instructions that come with the bush are only for the removal and fitting of the bush.
The compression arm is easy to remove.
All you have to do is remove the the small brace section which is below the failed bush, remove the nut from the rear of the compression arm (at the bush) and remove the nut off the ball joint end of the compression arm. Remove compression arm and take it to your guy with the press.
Refitting is the opposite of above.
