Does anybody know if the hub assembly is interchangeable beetween a 03 and 04? I have an 03 and need to replace it, and the place I'm looking only has 04. I wana get the 3 year warranty through them but I'm not sure if a hub assem. Off an 04 will bolt up.

 

You didn't specify front or rear, but maybe this will help:

It looks like they changed from a 40202H to a 40202M sometime in your time frame.

The rear is the same for all years.
