Front Wheel Removal on '03 S3

[MCSP3]

So I changed my rear tire by hand last night - what a job! This was my first go and it took about 90 minutes of Sweating, Cussing, and ***** near crying... Anyway, I had intended to change the front as well but my roommate's 19mm hex tool that he uses for his '05 Sprint does not fit. Is it an 18?

Thanks in advance.

No replies but I got it figured out. The Axle needs a 17mm hex which I found at Autozone after looking everywhere else.
