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!!

The rack is electric on these.  Motor, module and a belt that is inside the rack from the motor to the pinion/gear setup inside the rack.  

 

Are you getting any messages on the dash like "Service Power Steering Assist"?

Do you know of a diagram of all the components in the shop manual?

 

 

The only component drawings in the manual would be under "description and operation" for the power steering.  But its just an electrical component drawing in there showing what modules are involved for operation.

Yeah, there are no messages on the instrument panel. I can't draw codes with my scanner.

The truck just came out of the body shop, I hit a large rock and the RR passenger door, the RR cab corner, the side of the bed, and the running board were damaged. The steering problem started the day I pick the truck up from the shop. I bet they disconnected the battery, could this be the issue?

Did you hit the rock from the right front?  Or was it a sliding it?  

If it hit from the right front, I'd be suspect of a damaged rack.

All damage was actually aft of the left front passenger door. I iknow when you weld on modern vehicles you are supposed to disconnect the battery. The driver's seat position presets were gone, reverting else seems unchanged.

The 4 X 4 was engaged while the truck was in the body shop, most likely when they cleaned (almost detailed!!!) the truck for delivery. Thanks for the response!!@

      OEM Trailer Hitch Receiver - Impact tightened by shop

      By Chuck FB · Posted

      Great info to have, I printed out what you had in your document as well as Newdudes post as I could see this mistake with the hardware happening very often if not realizing what type of special bolts are being used and just guess on bolt size for torque or the good enough "easy" method as per whack in the used bolts with an impact and send it !.

      Auto start stop disable

      By dennismc · Posted

      I installed the Auto stop eliminator on my 21 Sierra SLT shortly after I got it. They have a detailed video instruction on how, took me about 20-30 minutes to do. I was apprehensive too to start tearing apart a new truck but it was pretty easy install. Like you mentioned get some trim tools. I went to Harbor freight and picked up a set. If you can find some install videos/instructions to give you and idea for a plan of attack you should be fine.

      OCI, not when but why?

      By Chuck FB · Posted

      If all oil manufacturers had to meet a higher standard for not just the initial filtering of the oil but that they had to improve on their formulation so that the oil cleaned the engine such as the Valvoline R&P or the new Mobil product ( assuming it works similar of course ), and the oil was changed on an interval based on good UOA data, there shouldn't be any gremlins running around like miniture rats on top of your heads to be washed down into the oil pan below 😁

      OCI, not when but why?

      By Chuck FB · Posted

      A while back on another thread there were comments and thoughts on air filters and I know that can tend to be a bit of a hot topic because of outfits that have a vested interest in selling aftermarket air boxes fitted with the gauze type of oiled elements touting the lower air restriction. However and unfortunately I don't know where I have seen the test results in the past about the amount of dirt through a test procedure that these style of filters do pass more dirt through than a properly designed ( not some cheap Chinese knock off ) paper/synesthetic media filter can do. Lake Speed had a conversation on that topic with one of the employees at Donaldson and there seemed to be a consensus of these oiled filters falling short in the absolute percentage of dirt holdback.    Which all ties back into how good the air filter is on the engine at keeping dirt out as that is going to reflect as a contaminant introduced into the oil as well as cylinder wear even if some of that dirt does find its way out of the exhaust rather then the crank case. Put another way that one can throw the kitchen sink at filtering the oil and using a bypass system which I fully expect will do nothing but good for the oils contamination but if the air filter system isn't doing its job then its preventing the engine from reaching the best wear/lasting case scenario instead.    Now perhaps this topic is or isn't for this particular thread but Grumpy Bear or anyone else for that matter, do you have access to some scientific trust worthy testing on engine air filter types to get some proper comparison data to post up.
