As others have stated it's easiest and makes the most sense to replace the arm (with an OE Lemforder). Without a proper press, either hydraulic or manual, you're in for a lot of frustration. Furthermore, it's imperative that the bushing be square to the arm when pressing the new one in or it will never be right.
The arms are actually pretty cheap and the payback in lack of frustration is well worth the extra cost. Anymore we don't replace bushings in favor of the entire arm.
