Depending on year/model, they all look sorta like this.

The boot we're talking about is sorta between #8 & #10 on the outboard end of each axle. The stub end sticks into the steering knuckle & hub, so unless you take the axle out of the car, you only see from the #8 pointer inward.

Remember, if the car's on the ground, with the steering turned all the way over, the outer CV joint will be flexed way over. But just follow the drive axle out to the hub & there it is.

If it has literally JUST torn, you can consider a new boot. If you don't know how long it's been torn, I'd get an axle assembly. If it's already clicking, you definitely need the axle.

Also, it wouldn't hurt to inspect the inboard boots, too.
