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.

Any thoughts?
