So I have an 04 f150 with 4.6 and the last couple of days my abs light comes on then the wrench light come's on.. I had the rear abs sensor replaced the transmission speed sensor replaced and MAF,TPS replaced a month ago. I was thinking it was the front ABS sensor's going out.

Hopefully you guy's can help me out

I got lucky once and pulled off a front speed sensor and found that it had a big build up of crud on the end of it. Cleaned it up and it worked again. Probably unlikely, but it's free to try. I don't know of a good way to check those either.

Well when the sun come's i'll have to try that.

Would any good solvent work for something like that or would you have to use electronics / MAF cleaner?

I think anything would be fine. It's basically just a magnet and it's not delicate.

Brake dust and built up road grime can cause issues with the ABS brake sensors at each wheel. As already suggested, try cleaning them first.
