What I did
I ended up going to dealer got replacement blade and took the insert out of the new blade and installed rubber insert into blade on car. If you want to replace the whole thing then a gear puller is required. You pop off the lower plastic cover which exposes the knurled hub of the motor that the blade is pressed onto. Use puller to remove from the knurled motor hub. MAJOR pain just for a wiper blade. Poor design. BUT I have seen worse design things on hyundai cars for sure.
Lucky I can reply here. Every time I have to sign into this STUPID forum I have to reset password as they have sooooo many rules on the password they think there protecting top secret files here. Freakin ludicrous
