Good morning, So I'm finally going to reach out to my fellow Silverado and Sierra owners. I have been dealing with a harmonic vibration issue with my 2014 Silverado crew cab 5.3 2WD for around 5 months. I have taken my truck into 3 different dealers to only have the driveshaft replaced under the powertrain warranty and it fixed about 40% of my vibration issue. The vibration can be felt in the gas pedal, steering wheel, seat, and it can be heard. It sounds a lot like a phasing boom. The dealer that replaced the driveshaft has said they now believe its my "CHEAP hancook tires" but I can duplicate the vibration with the truck supported on jack stands under the axle housing (not changing the pinion angle) with the wheels removed. Now with the wheels removed the vibration is not as bad but its still the same vibration I'm experiencing. One dealer told me I have a bent axle but I don't have any wobble side to side with the wheel on. the driver side wheel does look like it has a highspot with the wheel installed (you can swap wheels with the same results). the tech that replaced the driveshaft said he checked the axles and the checked out okay... Now I have yet to get a good dry warm day to throw a dial indicator on it myself to check but I wanted to check with yall and see what you think. the next nice day I get I plan on pulling the diff cover and taking a look inside. but any help would be much appreciated. I took it in to see about trading back into a Toyota and they didn't want to give me hardly anything for it and the new TRD Tacoma I drove just seemed so cheap for the $36,xxx they wanted for it. My Silverado has a lot more features plus im a fan of the LS engines so I plan on trying to resolve this issue before I try to trade it again. vibration is felt from 20-70+mph the worst is 55-65mph. running boards have been removed, new trans mount, new complete driveshaft. tires have been rotated and the vibration is still coming from the rear center of the truck. Vibrates in V4 & V8, and in neutral. I also have a case opened with GM on this issue since October 2018 so it's well documented. 2014 Silverado LT 5.3L 6l80e 2WD crew cab. (built in the mexico plant) 87,XXX MILES. Please keep the stupid comments to yourself. I just want to get this issue resolved so I can enjoy this truck.

2014 Silverado single cab 8’ bed WT 6 cyl. Just inherited this truck at 96,000 miles and haven’t driven previously so cannot say if instant or has been coming on for a while. So I’m in park and I put it in drive, as I give it gas it will rev up a little bit and then SLAP, POW, sometimes horribly bad and is scary to experience. If you’re making a mental note and put it in drive and wait a couple few seconds and THEN take off slow it’s a minimal feeling. The severity is directly related to how FAST or how high you rev it when you initially accelerate from P to D as well as how LONG you wait until you accelerate from P to D. If you’re not used to doing anything other (like myself) then slapping it in drive and taking off it is humongous loud and entire truck will jerk badly and feels like you just dropped a driveline. I do not think it is tranny related because I have no issues with the transmission itself while driving. No slippage at all and shifts perfectly fine albeit, shifting is to say somewhat jerky and noticeable. What do you all think? Put a notice on the steering wheel reminding me to baby and pamper it and she’ll be fine for many many moons or is it time to rebuild “something”
