I have a 2015 Silverado, 5.3, automatic, 4 X 4 LTZ, 4 door truck with 140 odd k miles on it. When turning the steering wheel 2"
to 3" from the center there is a growling sound, the engine slows (the truck won't idle forward or backwards without additional gas.
I replaced the belt on the thing that is located where a conventional power steering pump would be.
I have a Factory Shop Manual downloaded from the Internet, it's not searchable so you have to go through it to find anything.
The book says to pull codes, my scanner can pull tranny and body codes and the engine codes but not codes from the power
steering control module. I think its the belt driven member or the wire harness that also includes the control module.
Your Thoughts... TIA!!
