On my sons 450 we found some major looseness in the Swingarm. I bought a bearing kit for it. But when we removed the swingarm we found it is damaged beyond repair. The bearings were gone and the swingarm had suffered some deterioration. Ordered a new one and started putting it together. The new one has threaded holes for greasing the bearings which I find very helpful. Just have to find the fittings for it. Hopefully the local auto part store has some to match the threads.
