There easy to pull. The rubber strip seal has a thin stip in the center that expands the seal. Pull that out. Then from the inside, push the seal lip out. I can do it by my self. I put one hand through the window opening when I start it, Then finish pulling it out from the outside. I might be easier to have somebody else helping you hold the glass. It's a little harder if somebody glued the seal to the top. There not from the factory, but some people do when the put them in.
