I replaced my driver side CV axle (an original Saginaw) after ~340,000 miles, to fix a stubborn mild vibration. Used an APWI. The passenger side had been replaced with a GSP quite some time earlier (more than 100,000 earlier) and is serving well.
If your boots are shredding that quickly, you need to consider taking a different approach to installation. Alternatively, consider one of the new Cardone 'heavy duty' axles that comes with thermoplastic outboard boots like the originals.
