I noticed my factory rear bumper, the plastic one, has started slightly separating at the seam on the passenger side. This looks like what we saw on the steel bumper groups.

About 1k miles and only driven on dirt roads. Granted these were dirt roads in Moab where minor flexing occurs—but when I say minor, I mean it. The pic shows about the max I flexed it.

Is the frame flexing? The body? What’s pulling it in? In the second and third photo it’s hard to see but the bumper has scratched the paint.

All stock.

That happened a lot on the JK 4dr's also--just too much body on the frame and the usual cure was aftermkt bumpers--

A lot of the time it is caused by coming down forward off a ledge and that usually force the rear bumper up/in--even an ever so light "RUB" causes the bumper/body trauma !

It goes with the territory !

@Jaym - just curious; why is the bumper so shiny? Is it a high gloss paint or plastic protection? Maybe the Rubicons have high gloss bumpers?
