Usually whathever you try to get a component rocking around an axe with an angle will result in terrible failure. The game just doesn't want it to happen.
Here's how to force it.

Let's take the steering wheel as an example. Create it and place it normaly in your model with the angle etc. Be sure to make it a separate component though.
When you're ready to go into PT2 duplicate the steering wheel component and rotate it so that you remove completely the angle and align the steering wheel with one of the X,Y,Z axis. Remember the angle you needed to make it parallel with one of the axes as it will be used to give that angle back to the steering wheel through a groove. So keep the model like it, with two steering wheels at the same position but with a different angle. And export to PT2 and continue your work.
In PT2 don't try to make the steering wheel a correct actor (a correct actor is centered on 0,0,0) just let it there as we'll use absolute coords later to specify its center. However in PT2 create an empty dummy as a child of the steering wheel then drag it back under the master component and put the steering wheel inside it. Rename the dummy ST_DUMMY.ACT or something obvious. Oh BTW you can delete the steering wheel in correct position.
Now calculate the absolute center of the aligned steering wheel, or at least it must be the point around which the steering wheel was rotated to make it parallel with the X/Y/Z axis.

Then use these grooves:

STWHEEL.ACT			-> This groove is applied on the SW mesh. It's the usual rocking groove.

NEXT GROOVE

ST_DUMMY.ACT		-> This groove is applied at the parent dummy. It gives the angle back.

x			-> Axis that will get the angle back.
60			-> The opposite of the angle you used to align the SW with one of the XYZ axis.

It's easy to do little mistakes with the angle but it's quickly fixed. If you wanna see that trick used. Test the General Lee or the Sor BN12.
Don't forget to add the groovyfunkref (here it's the number 20 in the first groove chunk) in the text file as well.
