Ok guys the other day I attempted to pull out a trailer with my 95 foreman 400. I heard a pop after that I have had no rear wheel drive. I have torn her down three times and thought I’ve found the problem but upon putting it back together still nothing. While on stands with all wheels spinning I can grab and stop the rear wheels and it makes I popping sound from the rear end I tore it apart and cannot find problem. I replaced the drive shaft because the splines seemed worn. I am out of ideas please tell me someone out there does.
