Hang on, there's something not right about your rotation code if you need to adjust all of those joint setttings. They shouldn't need adjusting once initially set up.
If you try the reset code I posted earlier for Chunkations in the car demo, it shows the car can be rotated without affecting the wheel joints. See code 5 posts above ^
