TRX500FA suspension problem

Hi
I have had my frame/suspension connection on The back right side come apart on me. I was coming down a hill with the back brake on, hit a bump and when the back tire came back down on another bump I heard a metallic sound and then the back axle was dog tracking. I was able to use a sling to keep the axle assembly connection point close to the frame to allow me to limp back to the truck and get the machine home. Now I have to figure out how to re connect it. Anyone have this problem in the past? I will start by trying to download service manual.
Any advice would be appreciated.
