You can use a socket set and a vice. Find a socket that just fits on the end of the bearing, but does not contact the aluminium of the actual linkage. Find a big socket into which the bearing can pass to seat the linkage against the other side. Now you CAN hit the smaller socket with a hammer, or you can put the whole thing in a vice, check everything's lined up, and tighten away. The smaller socket will drive the needle bearing out of the linkage.
If you have one of
these tools, or similar, you can use it to start off the process and not worry about having everything lined up, but the throw on mine (the one pictured) is not sufficient to drive the bearing out completely.
