thanks for any info and tips, was feeling really weird to the left, like a blown shock so I take a look around and its missing right at the bracket under the bulkhead where it comes out.
Really not too hard, replaced a broken one on a friend's 07 600 RMK a few months back.
Just unbolt the two sway bar mounts on the tunnel and drill out the two rivets on the other mounts and work it out. Then you'll have to disconnect the bottom of one a-arm to get the new sway bar in.
