Swinging Arbiter glitch

On the level of The Great Journey, you can have the Arbiter swinging around on the sand along with the Scarab without the player controlling him.

Please note that when the Scarab walks around, the entire vehicle will swing back and forth between steps. This observation is pretty crucial to the trick.

Instructions
Commandeer either Banshee that the Elites give you on the platform, during the phase of the mission, "Backseat Driver".

Destroy the three Wraith tanks that the Scarab is targeting and make sure the Scarab will start moving, after the tanks are destroyed. If not, check the area if there are more enemies hampering the Scarab's way.

When the Scarab starts moving, set the Banshee down on Sergeant Johnson's Scarab and ride the Scarab until it reaches the middle of the canyon, with the huge rocks in the center. Jump off the Scarab and make sure you land on a slope of the rock, in the middle of the canyon, so that you survive the fall. The game will still think that you are on top of the Scarab, even if you are on the canyon floor, because you weren't meant to survive the fall on top of the Scarab. You will continue to sway and swing around the canyon floor along with the Scarab.

After you are on the canyon floor, your survival is not guaranteed, for Brute-controlled Ghosts and Spectres will attack you, while you have little control of the Arbiter in his "swinging mode". If you wish to exit the "swinging mode", you are recommended to revert to the last checkpoint, because committing suicide with grenades is futile. This is because if you pitch the grenade while are you swinging, you may not even hit yourself with the grenade, and reverting to last checkpoint is easier.
