On my 04, Ive installed my passenger cv axle twice with in a month and need some advice on what could be causing my outer boot to bust each time I take it out for a test drive after I get it installed.

Well I purchased the car with the factory axle in working order and one day on my way to work the outer boot busted. So I replaced it with a new Cardone cv axle. Well within a week the outer boot busted so I got another one and it did the same thing again. So what could be causing this issue?
