actually i changed the axles the day before but i know i got that nut tight. Would bet my life that it was tight. and it came loose in a day. that control arm and ball joint is only a year and a half old. So i went to carquest and got another one (better than vatozone shit only got autozone shit last time cuz i was short on money. I'm going to locktite the nut this time also and check it after everytime i drive for the next couple weeks. Downtime will probably be only through tomorrow. Would have been only today if i had noticed the axle sooner but i had to work today so i did not get to look at it til 9 or so. but ya I'm lucky i wasnt on the freeway cuz i was heading to the freeway. That could have been bad
