Ever since I went to the track and raced 3 times I have been having problems with my axle. I have a eg civic with a ls transmission. The axle that keeps coming out is on the passenger side of the tranny. I know I shouldn't have been taking it to the track but the tranny is very new still and it shouldn't be giving me problems. I didnt have any problems till 2 days after I went and my axle popped out at a stop light, I got it back in and it seemed to be fine until last night when it came out again on my way home at 5 am. The axle wouldnt go back in for anything, but finally it did after an hour and i made it home. Is there anything I can do to fix my problem of my axle coming out?

I have talked to 3 people and they all say different things.
1. my axle is too short and I need a longer one
2. i have no lsd and i need that so it wont happen again
3. because my car is lowered the axle comes out sometimes

Any suggestions?

Thanks
