Hey guys, I'm back :)

Alright, I'm not sure if I metioned this problem in my other thread like, 3 thousand years ago but the rear bearings keep going out in my '93 Bird. My dad had them fixed once, but then a few weeks later a horrible knocking noise started. First only around corners, but now its all the time, going straight and turning. He been talking about getting it fixed again, but I'm not sure it can be fixed. Can it?

Also, I have to keep the axel nut wrench behind my seat so incase I have to tighten it up. I know it's not supposed to be coming loose. What happens if it starts to become loose? Is something more wrong than just the ball bearings?

BTW, it's the knuckle that went wrong. Dad found a part on ebay brand new and won the bid at 99 cents.
