Did you buy this from a guy called atvexpress?
I needed a second set of racks and found that his were advertised as new for 50% off retail.
Well, they weren't new, they were actually very used. We had the same issue with the springs and our edger fell off going down the road. Currently in the process of getting him to make things right, but I ordered some new springs from Jungle Jim's...hopefully that will fix it.
