I tried rubber mallet, hammer, crawl under the car and hammer it HARD. Just won't come off. After making all kinds of noise for over 30 minutes, ya, 30 minutes, I quit! This shit must be soooooo rusted to the hub, I was thinking. Better let the garage to handle it. Next 20 minutes, I put everything back on..........

This morning, I just can't help thinking the whole process in my head over and over again. Suddenly I realized, SHIT! I was SOOOOOO stupid!!!! I forgot one thing! No wonder why it stuck to the hub and not come off.

I'm sure you all know what I forgot...
