Annoying Squeak every time cylinders reactivate from V4 to V8
Z71Texan posted a question in Ask the GM Technician
At 1800 miles I noticed that my truck started or has been making this really annoying, high pitched squeak every time it switches from V4 to V8 on the highway. It almost sounds like a valve opens up when the cylinders reactivate and is driving me nuts!! I don't hear anything when it goes from V8 to V4. Unfortunately, I don't get to enjoy the "quiet cabin" GM advertised because of the squeaking. Has anyone else experienced this issue? I have the 5.3L V8 in a 2015 LT Crew Cab short box Z71 -

Hey guys! Hoping I can get some help on this...my truck out of nowhere started making this horrifying noise on startup, primarily during cold starts. I’m very concerned. -
No shake at 80, vibrations are minimal. Only changes lately are personal oil change with 8.5 quarts not 9. I can see oil at full mark for the first time since buying truck and not beyond. Rancho adjustable shocks all around at setting 1 on fronts 3 on back. I keep driving 80 everywhere in amazement. Such a relief!
