i had the usual issue that we all have where the middle piece of the rear bumper assembly kept rotating and the bumper was folding up.
quick fix!
step F-5 in the manual
apply some CA glue between the where the “oval” piece bolts to the “X” piece. Do this with the bumper fully installed and do one side at a time so it all stays aligned. Take the screw out of one side, pry the joint open just slightly, put in a heavy drop of CA into the surfaces of the joint, put the screw back in and tighten. Repeat for other side.
the middle piece no longer rotates and the bumper is significantly more durable.
as usual...YMMV
