Last fall I had both axles go bad with in a week so I had both replaced, then the passanger one tore the boot off and from the looks I think it twisted the inner bearing/universal (whatever the thing is called) and the driver side started shaking again. So I replaced them both and they worked fine until tonight I noticed the passanger boot ripped off again (on the inner side) so I checked and nothing is catching it to tear it. The axle doesn't shake or make noise so I didn't notice until I had a flashlight looking at random stuff and noticed it, and that its completely dry, well theres grease everywhere but my axle LOL. Any input on what could cause this and what a good replacement axle is. also if it matters last fall during the time my axles kept going out I went through both front wheel hubs twice and a third time on the passanger side.
