I have drive shaft shop axles, and a basically stock motor. I have been doing some auto x and accelerating at very sharp steering angles. ( steering wheel turned all the way). Could that just be too much stress on the boot or culd it be something with the axle? Thanks

 

If you are doing autocross...you should know thats going to tear up your car.
things break when ever you run them hard like that. Thats how it goes..

 

check and make sure your front and rear mounts are not torn.

 

I have Enjo axles and saw that same problem on the outer boots, not tearing but the bands were aparently not tight enough and the grease was slingin all over the place. Its a little disapointing when your stock axles didnt do that and the aftermarket ones you dropped all this money on do.
