Vacuum Booster Replacement

Just ran into this issue on the way home from work tonight. Went to pull out of a parking spot and when I turned the steering wheel to the left I felt a grinding/rubbing in the steering wheel and could hear it outside of the truck. It made the same noise turning the wheel both directions. Also made the noise and felt it in the break pedal when applying pressure. I talked to the guys at Cutting Edge Diesel in Forest Lake here in Mn and he said it sounds like a bad vacuum booster. Is this different than the vacuum pump? And does they vac system tie into breaks and steering? I have the ESOF and OEM hubs.

Thanks in advance guys

I wouldn't be calling that location for diesel advice unless you confused the terms.

Our diesel trucks don't have a vacuum booster. But it sounds like you have a bad power steering pump, which supplies power for both the steering and brake hydro-booster.

I may have confused the terms that they used, but the stuttering brakes and steering is typical of a power steering pump? I'm sure there a thread on replacing that on here some where.

You can have an issue with either the hydrobooster or the steering gear having an internal issue that effects the entire system in this way, but more often it is the supply, the power steering pump.
