I would try using micro drill bits to drill a small hole in the centre of each part and then insert and super glue a suitably sized piece of wire into the hole made in the axle in the chassis part. You can then push the wheel onto this using the hole you drilled into the wheel part of the axle and use super glue to attach it. The wheel will not rotate using this method and will not be as strong as the original but l have used the method successfully for creating new axles and for lowering stance etc.

Hope this helps.
