Could you please tell me what problems I may encounter after driving my truck in 4WD on ice for 500 miles with ATF in the front diff?

Probably not a lot. Just put the correct stuff in and then see if you hear anything normal I'd doubt you will.

I agree with HMAC300, here is how to change the differential oil and add the correct fluid to help you.

SAE 80W-90 GL5 Lubricant

Check out the images (below). Let us know if you need anything else.
