Hopefully, someone can help. I have 2014 2500 at 60,000 miles.
I started hearing a hissing sound when I’m in the cab, and it’s coming from the steering area.
When I push the brake, it goes away for a second and comes back.
Also, when you steer, it goes away for a second.
I read on other forums that there is a tube inside the high-pressure hose from the steering pump to the booster, and it can migrate its way into the booster and make a sound.
I checked the hose and did not see the tube inside coming out, so I don’t think that’s it.
My brakes and my steering seem fine, and my steering reservoir is full.
