Did a search but couldnt pick anything up. I wanna swap my S4 stock steering wheel with an S5 one I have laying around, it should be a straight swap right?

 

It'll bolt right up.

 

Cool thanks

 

Ok problem, when I take off the center Mazda circular piece, how the hell am I suppose to get to the bolt since the whole cover won't come off because theres two screws inside.... Long extension?

 

take the 2 screws out and pull the center piece off...

 

The two screws are INSIDE the cover, facing the back of the wheel...aka you can't get at them.

 

I assume you are attempting to remove a stock S4 2-spoke steering wheel:

-Remove the 2 screws on the back of the wheel (from the back)
-Remove the center nut with a long extension and remove the center section of the steering wheel
-Remove the steering wheel with an appropriate steering wheel pull
-Throw the hideous S4 steering wheel in the garbage and replace with a well designed S5 3-spoke, preferably leather-wrapped

Enjoy!
