I have a duradlue axle on my Z and noticed that the rear break disc has some play in it. I had the axle installed by the dealer and the day I got it back I had to tighten the swing arm bolts and the axle locking nut cause they were all loose. So I am wondering if anyone has had this problem or has an idea of what it could be? It could be a result of poor installation though. The play is forward to backward, and it is only about an 1/8th to a 1/4 of an inch. But I know this shouldn't be there. Any help would be greatly appreciated, so that I have an idea before tearing into it!
