"it just says off all the time even though I can still switch it on and off."

"Yeah the abs light is out so I assume they're both on"

This is confusing. What you are saying is the the TRAC OFF light is lit up all the time, yet your ABS light on the dash is not on?? Maybe I'm not following....

I've never been able to turn my trac control off and on using the button when the light is on all the time and there is an ABS light on constantly on the dash. When the ABS light is on Trac control is disabled and button won't do anything. I drove my 00 GT around like this for over 6 months and trac control was always off and pressing the button could not change that.

IF you have an ABS light on then get that hub changed and I'd bet that the trac control button will work as designed. And yes, Timkin hubs FTW. Check out RockAuto for them, seems to be a good place to get them. If you need one in a hurry then I think Autozone carries Timkin hubs but the price is higher.

Depending on how much play is in that hub it may not even be that, it could be the wiring or the connector to the hub. My front pass. side wire harness was rotted out about 7 inches back from the connector causing my ABS light. Took a while and a voltmeter to find that one.
