Wiper arm linkage bushing FRUSTRATION!

So I need to remove those arms and do it outside the car? There's no room to put a socket onto at least the top one and the lower one is probably too tight.

Also, any tips on how to get the top one back off now? I'm having a terrible time with it!

Definitely easier to take them out completely, but you should be able to pull it down far enough if the other side is already on. To remove bushing from post, slide a wide flat blade screwdriver under edge and twist till it pops off.
