My front wheel is squeaking when I turn left

I have a vw jetta and the abs light has been on and and the brakes where jumping and I could hear it in the front drivers wheel so I went and got new brakes and rotors for both front wheels and that didnt help the abs light is still on and the brakes still jump and when im driving there is a squeak the the front driver side wheel and it squeaks more when I turn to the left
