Strange wheel behaviour

Hello. Working on a new prototype car, we have encountered a strange error.

Even though the pivot point is in the centre, the wheels in game are not(two are, but they are off).

Here is a wheel in max showing all four of the wheel parts are selected, and that they have the same pivot point.


Here's the car in-game. You can see the rear wheel is sort of in the right spot, but it's not where it should be. The others are not even close, and they swing around like crazy when you try to drive.


Has anyone had this problem before, and fixed it? Any help would be great.

 

Also let me add, that the car looks perfect in the spinner. Just in-game is where it's messed up.

 

Done that a number of times. No dice.

 

I exported some of the objects with the wrong settings. Now it works.
