Hello everyone! Hoping for a little help. My 2002 MXZ 700 Sport needs the right trailing arm replaced. Located a new one online but need bushings as well. How many do I need????? New to snowmobiling and really not sure. A mechanic will be doing the work as a favor but I've gotta source the parts. Don't honestly know what I need to buy along with the trailing arm for an easy install. Any help (and some snow) would be greatly appreciated!
