Cheers

  The filter under the OPS is for engines with AFM, which didn't start for trucks until 07.5 I think around '02/'03, when GM rejigged the computers and wiring, they also moved to a multi-pin OPS, but still didn't have the filter under it.

  Because everyone hates them. They have all the downsides of a truck, combined with the downsides of a 'burb, and then add in a hole in the roof.

  Hi everyone, looking for some input on an issue I’m having with my truck. It’s a 2016 2500HD Crew Cab LT with the 6.0. A couple of months ago I had the pitman/idler arm and tie-rods replaced at a shop with some good quality parts and then professionally aligned after that. Immediately I noticed that the steering is much tighter/heavier feeling and has zero play of any kind. However the steering will not “return to center” at highway speeds now, for example if I’m going around a slight curve with the wheel turned and I let go of the wheel the truck will continue to turn instead of the wheel re-centering like it used to. It makes it so I’m constantly fighting to keep the truck going straight down the center of the road. I should also note the truck does have the “NV8” electronic steering assist. I’m wondering if I need to have the steering control module re-programmed? Or is it an alignment issue? All of the alignment parameters were in spec from the shop. Maybe someone else has had this issue, I appreciate any feedback, thanks!
