    OK I get it and I have one of those calipers. But pardon my ignorance but which part of the ball joint am I measuring?

    In order for me to take the measurements, I would need to unbolt the ball joint. Would the steering geometry remain the same if I put it right back in after taking the measurement? I apologize for the rookie questions.

    Unbolting the ball joint and putting the same one back on will not mess up steering geometry. You need to put both front wheels off the ground to do the job.

    Looking at the picture of your boot, it seems it just might be a case of "cracked rubber" that still keeps dirt out and grease in. If thats the case, you could spray the crack with brake cleaner to degrease it, and apply a little HT-silicone on the crack to keep it from breaking open beefore you get a new one.
    I certainly would try to get a replacement boot, but If you can't find one, get an aftermarket control arm. They are not expensive, but do have front axle geometry checked after replacement.

    Patching the crack is an excellent idea -- definitely cheaper and faster. I will definitely go that route first.

    Thanks again for the help.

    Remember, patching is only a temporary fix till you get a replacement.

    Yes, just like tire plugs are "temporary".

    Temporary until the tire is worn out.
