My two most challenging issues...

Two more issues that I'm plagued with:

1) The front CV boots are both torn. Should I replace just the boot or the entire axle? The independent shop I take the car to indicates that replacing the boot itself is nearly the same price as rehabing the entire axle. Thoughts?

2) Nobody in the Southern California area seems to know how to align the front wheels. What are the specific settings that work best. The insides of the front tires were wearing, now the outsides are almost bald after having the alignment redone. I know this car historically wears tires in a strange way due to the AWD.
