Wheel Bearing Options

[Boss-Celica]

Whenever I drive past 40-45mhp I hear this humming sound from either my rear or front driver side wheel. I am pretty sure its the wheel bearing. I was wondering if our cars need to have the bearing pressed on with a special machine, because my friend said some cars do and some don't. Does anyone know if the bearing needs to pressed on?

How can I figure out if my front or back wheel bearings need to be replaced??? i think its the front my but my friend (the car dude) thinks its the back ones because of "the humming" noise....

back in january i ran over something on the way up to seattle that was so hard/sharp it cracked my front right rim!!!!!!! then back in march my friend was putting my spare tire on my front left side for me on his slanted drive way & the jack came out from under the car which caused my poor baby to hit the driveway on the front left corner w/ no wheel to hold it up ....i think thats around the time the humming started!

so thats why I think its the front wheels that need new wheel bearings...! the back wheels havent suffered any retarded accidents....


what do u guys think?? front or back? lol

im going to buy the bearings today so i gotta figure it out...hmmmm
