I am trying to change the outer hub assemblies on my sons car. I cant get the nut to turn to take everything off. Is it a normal thread. right tight left loose. Any ideas? The reason for changing them is that the car is making a very loud noise. I tried different tires and it does seem to make more noise when you turn. Should this fix the problem if I can get them off.

 

I just took off the passenger side wheel and spun the hub around and it sounds like the noise is actually coming from inside where the axel is where the boot is around the axel. Please help what do i do now.
