When I was removing the roll cage so I could remove the cargo bed plastic, I unbolted the roll cage the front passenger side bar the bar sprung forward about 1.5 inch. When I unbolted the roll cage front driver side bar the bar sprung outward about 1.0 inch. I do not know if this common with all side by sides or I got a bad part. The joints where under a heavy preload .
The frame is basically a truss structure, it's common to design such preload to help stiffen the structure.
