2024 Gmc Sierra 2500hd Running Boards Not Working. That’s why it’s a good idea to install a pair of gmc sierra 2500 running boards to improve your truck’s level of accessibility. There seem to be two pins in each bracket.

It’s common for the running boards to partially extend, only to immediately retract again. When i test drove it, i noticed that i could feel every bump and crack in the road through the steering wheel.
