turn signal assembly removal

My shifter has been hard to pull lately and last night I finally managed to snap it. I got the shift lever off and could just spray it with some wd40 and put in a new lever, but I want to take it apart and clean it so it won't happen again.

I got the steering wheel off, now i need to get the turn signal assembly off. It seems I need to use a puller on the bracket holding the turn signal assembly in place? or is there some other trick? After that piece has been removed I assume I will be able to clearly see where the shift lever attaches and throughly clean it?

Thank You
