I have a 1997 Honda Civic LX that I am having some problems with. I recently replaced the CV shafts and lower balljoints on both sides of the car. Not long ago my brother was driving and the lower balljoint came out of the knuckle and the CV shaft separated on the driver's side. I thought that it might have been possible that I somehow forgot to put the cotter pin in (unlikely but possible). Luckily this happened in a parking lot and my brother wasn't hurt and the car wasn't damaged too badly. Anyway, I had to get a new balljoint and CV shaft. This time around I made sure all the torque specs were correct and made SURE to double check the castle nuts and cotter pins. Well, it happened again (same side, driver's side). This time the outer part of the CV shaft separated from the stub shaft in the knuckle and the balljoint popped out of the knuckle again. In addition, the accident also tore the brake caliper hose in half. Again, it happened at low speed and nobody was hurt but this is unacceptable. This time there was remains of the cotter pin in the ball joint so I KNOW it was there at one point in time. What would cause this to be happening? I need to get this fixed before I can trust the car on the road again. Thank you for any help anyone can give me.
