I was doing some poking around to familiarize myself with transfer case maintenance on our 2019 Nissan Pathfinder and I came across this youtube video. I hope to not need this done to mine at any point, but what's got me curious is what is holding the engine in place while this is being done? It looks like it's swinging in the breeze. Some type of underhood brace? https://www.youtube.com/watch?v=GDUN0PD3g3k&t=15s
