We had that problem in our Highlander. Check to see that all the doors are closing securely -- including the rear hatch. That was our problem. We'd go over a bump and the thing would start going *bing bing bing*.
It should NOT be skidding. From your description I think you are mis-interpreting the "skid light." An '04 Highlander is equipped with an ABS system and the fact that it skids at all is indicative that it is not working properly. The "skid light" that you refer to is actually a warning light that indicates that the ABS system is malfunctioning! You should be getting it to a mechanic or dealer right away to have it fixed.
