Ok..
So, just went to Autozone to grab some CV axles for my 95 4runner. They had two part numbers, one for with and one for with out ABS. They stocked the part with out ABS....is there really a difference between the two?

 

i do not recommend getting parts like that from autozone they are pos to me i had experience with them. I went through 4 of them with in two months. They were hypertensioned or else the boot would rip again within two weeks. They are salvage parts, i don't have a problem with salvage parts but they are as low as you can get. I would say Napa CV joints are way better it has been a year of rough driving and it is holding up fine. To sum everything up to your question is there a difference, i believe there is not a difference if they had both is stock you can check them out and compare. You should really go to Napa instead of autozone

 

Edit: The difference is that though they are nearly the same design on triggers the ABS sensor and one does not....and costs $30 more.
