Probably the best way would be to use an arbor press. Use a socket that will pass through the opening but still contact the outer race of the bearing. If you don't have an arbor press available, try using a bench vise. Place the parts in the center of the jaws. You'll need to make a spacer between the jaw and the linkage, so the bearing has a place to go. No press or vise? Try a small amount of heat (<250°F) to the OD of the linkage. If it's aluminum, it'll expand more then the bearing and with great care, can be driven out with a screwdriver.
First use a small flat head screwdriver to remove the dust seals. I used a larger flat head screw driver and taped the bearing race in 12 3 6 and 9 o'clock positions and got one side out, then dropped a socket with a extension to press the other side out. I didnt use heat and it took a good blow with a hammer to get it out.
