Not sure if this is in the right area of the forum, mods feel free to move it.
Last summer, during a trip to the Canadian Maritime region, I had the rear subframe break unexpectedly. Yeah, I know, I should have listened and not overload the top case.

To finish the season I used JBWeld and hose clamps and removed the top case.
Removing the subframe isn't a big issue, just remove all the screws and plastic panels. Note where everything goes and take lots of photos.
New subframe in. New Givi TopCase support.
