Just like longhorncop, I fixed my Chevy Shake issue too. The last straw was a horrible ride back home from a job 3 states over. After hearing ice smash against the sides of a cup filled with soda so loudly for about 5 hours, and the faulty bluetooth, it was done. The truck had to go, and fast. Something is clearly wrong with the 1/2 ton GM trucks. Mine was a regular cab short box. Everything fell into place to dump the truck - and I did without hesitation. Dealership opened early on Sunday and the 150 mile trip was strangely enough very smooth with the Chevy. No idea why but I don't care about it any longer. For those lingering with a Chevy Shake truck, dump it or get GM to buy it back but buy the replacement from a different manufacturer. RAM, Ford and Toyota make great trucks. Check them out - they make great trucks.

Nice looking POS. Hope you get it resolved to your liking.

Great pics BTW. Black is such an awesome color choice when new or kept like new. But keeping it looking like new takes a lot of effort, time and desire. Every time I see a perfect finish on a black vehicle, I know the owner has spent a lot of effort (and perhaps money) to have that appearance. Nothing beats the looks of black when clean and in perfect condition.

Update: vibrations came back. Thoroughly disgusted with this truck's vibrations. On my drive yesterday morning, it shook so hard, it felt nauseating. GM lost their ability to build a good truck, imho. As there's no effective repair yet, the thought of ditching this silver colored turd is tempting. Lesson learned. You are so right about come and go. Kind of like a bad girlfriend - stays around too long and comes back too soon. Yup, thought fuel would be the source but not even close.

My truck had the shaking/vibration problem. In this huge post, there's been a few theories about the cause of these vibrations and it seems the fixes haven't worked well for all. So I decided to skip over the idea of bringing my truck into the dealership for the part swapping expedition and decided to live with the condition. If you read carefully, I used the past tense describe the vibration issue. For the past month, I've been using gasoline from a 'top-tier' station (Costco). Initially, there was slightly lesser periods of vibration and the amplitudes were definitely on a smaller scale. For the past two weeks, I drove my truck as my daily driver to see if the vibrations would continue to lessen. Each fill up was at Costco. My daily commute is about 170 miles. Today, my entire trip was vibration free, a first. It was a gradual process but this is my theory: the 5.3L engine must suffer with carbon deposits on the surfaces of the valves (and other components) and using gasoline without the higher levels of detergents found in the top tier gasoline more than likely assists with gunk forming on the valves (and other components). I have just over 5400 miles on my truck and the first vibrations became noticeable around the 1200 mile mark. The other thing I notice is there's more pep to the engine. Pushing down on the gas pedal seems to be met with a smoother engine response and the acceleration doesn't seem to lag. It's quite an improvement on regular 87 octane gasoline. If you're wondering about 'top tier' gasoline, there's plenty of information found with a basic internet search. There's a few brands offering gasoline that qualifies as 'top tier'. Lastly, this may be purely coincidental about using a fuel with more detergent and experiencing declining vibrations to the point it has disappeared. I'll keep using Costco gasoline and if those happily forgotten vibrations and shakes return, an update will be made. I lost count on the number of tanks of fuel consumed but it's a big number of refills.
