I got two steers that are physically the same, both of them are parented to an Empty which is rotated in X axis, but both rotate differently when I see them from camera point of view (while holding R), in this picture you can see how the top one (steer 1) rotates 90 degrees in Y axis while X and Z remains in 0. In the other hand, the lower one behaves completely different, it rotates 90 degrees in Z axis while X and Y values are also being changed:

The real problem with this is that I'm building a game with working steers and using only Y axis to rotate completely simplified my life, sadly the guy who did the steer that rotates correctly at Y axis is now unreachable. Now all I want to do now is to imitate that behavior, all the steers I made are suffering from this issue. I've already tried clearing Scale, Rotation, Position, etc, getting this problem with the steer that was supposed to work fine made me to ask for help.
