cruising home today and i notice a weird shake in the K5. i took a corner into my neighborhood, and i kid u not, it felt like i had 4 wheel steering. im like wtf? somethings broken?? get home and discover the rear driver side center pin in the springs has broken off and the springs moved foward a good 5 inches or so.. is this a common thing to happen? also, how the hell can i fix this btw, its a 12 bolt rear end, stock springs with a homemae shackle flip..
