On both my current civic and when I had my del sol, when ever I back out a driveway and turn at the end (read as very slowly) I head a thud noise coming from my hub area. The axles were used on both cars, so that is now what I am thinking is going. I know the normal sign is a clicking when you make a turn, but I have never had that happen. Since I have never had an axle go on me, I don't know the signs. What do you guys think. I could see them going since I have autocrossed and draged raced on them a decent amount, and I have no clue how old they are. When I drag raced, I would always get tons of wheel hop, and would lunch hard, so I know that will kill OEM axels quick.
