Response from BM Cars service
The BMW 3 E46 uses aluminum control arms as standard, where the pins cannot be pressed in. At the manufacturing stage, the control arm is heat treated, so the strength of the embedded pin is assured. Attempting to replace a pin in a control arm usually ends in its significant weakening or damage.
In the aftermarket, there are specially prepared Meyle HD front control arms in which the pin can be replaced (pressed in). These are specially reinforced. In your case, it would be necessary to first replace the regular control arms with Meyle HD and only in the next stage replace the pins themselves.
