i just wondering, after i finish work today when i start my car by turning my steering wheel little bit without moving the car, my idle goes up and down and i hear something. it just happen today is it the steering fluid? I didn't check it when i got home. and couple days ago, i smell burning coming out from the hood its not a smoke but somethings burning. And i notice that since i got my diff change front and rear, there's some spot or leaking underneath the car after i move it. So what's the problem of my car? i need serious answer here please. thank you in advance.
