Did a steep "double incline" turn hurt my truck?

I took the wrong exit for a truck stop in a construction zone and the end of the off ramp was uphill. I had to take a right turn into a steep downhill. Durring the turn I heard a noise almost like nails on a chalkboard. After the turn I pulled over and inspected the fifth wheel. Everything looked okay aka no cracks or bends. The truck goes down the road fine. That noise just got me a little worried and I'm wondering if there is anything I should check or look out for. Its probably nothing i know but better safe than swifty.... whoops i mean sorry

 

Didn' think to check the mud flap hangers which are fine, the fairings are good. The tractor is parallel with the ground.

 

I think you hit the buck in the eye with this. The sound happened right where that part of the trailer was at the crest.
