At the end of the quest you are prompted to kill the remaining raiders. Well after all the raiders are dead the quest doesn't end! Ironsides keeps saying something about bearings! Ive just by past it for now and is currently doing other things. But it would be nice to go back and finish it eventually! Plus i heard you get a sweet gun for finishing. Any help would be much appreciated.

The end of the quest is getting Turbopump Bearings.. So unless you've done that, the quest isn't over. You might have had a random raider attack as those can happen at any time you are on the ship. .. The last attack is by a ton of scavengers, including Mandy.
