I was doing the whole, clean & grease the swing are bearings. While in there, I took out the triangle shaped linkage. One of the bearings is totally shot. Play in all directions, dirt & grit in there. It's the smallest one on the linkage, it connects to the bottom of the rear shock. The dust seal was mangled up a bit, and since I haven't had it apart before, I'm sure the factory screwed up the seal. Just FYI to everyone with a pig. check all your suspension bearings once in awhile.
