Same problems on my 07. I put it off too long and I ended up replaceing stator and ring gear. Ring gear was eat up in 3 different places. Not too hard of a job aftre discussing it on this site with lots of encouragement and tips. I also replaced the inner primary with chrome while I had it down. Made a 4900 mile trip to Glacier National Park from East Texas afterwards and no problems other than Y pipe mount and pipe broke in near Vernal Utah. HD in Vernal were real friendly and jumped right on it. No pipe bracket so shop foreman welded the old one back together. I was out of there ina couple of hours.
