you can do this yourself, it's not hard...
make sure your car is parked on a flat spot... align the wheels so they are pointing straight where you want them to be at...
take all of the plastic shrouding off of your steering column...
remove the 4 bolts in the back/side of the steering wheel i think they are star drive...
take off the airbag and carefully disconnect the airbag connector... ignore the airbag warning tag... lol
take off the big bolt in the center of the steering wheel, i believe it's 17mm...
carefully pull the wheel off of the spline without moving the wheels...
put the steering wheel back on how you want it (straight)...
put everything back together...
note: if you want to be extra cautious, disconnect your battery cuz if the airbag connector happens to short, it will blow up in your face... this is like 1 in a million but it's up to you...
