    You indeed got lucky! Good luck with the new truck. Let us know if it shakes!!!
  2. Bart’s Silverado
    Your welcome. They are top notch and so are their shafts. Mine is a 2wd and for me the shaft took out all the shake except for the normal tire balance issues. I’ve determined that the 20 inch Goodyear RSAs are just cheap tires. Similar construction to their 17 inch cousins for police cars. I ran them for years on my cruisers. The state paid a whopping $43 per tire!!! Cost does equal quality in a tire. My truck is currently running 17 inch wheels from my old Tahoe and Wal Marts cheapest Goodyear tire in 265-70/17. Rides very smooth and the tires seem to last very well.

    Call Performance Drivelines in Barstow CA and order their two piece steel driveshaft kit. It will fix your truck. Also much, much cheaper than trading or legal action.

    You have a bad set of tires unless their machine has a problem. As them when was the balance machine last serviced and if it has a history of becoming out of spec over time. If the machine is not the fault, call BFG customer care and lodge a complaint for new tires. Bad ones are made every day and it only takes one to make your truck shake like a buckboard.

    Yanking our that mile long, fat ass aluminum drive shaft and replacing it with a heavy duty steel two piece shaft with center support and carrier bearing cured my truck of ALL vibrations. It now has gone 20,000 vibration free miles and I expect many many more. With the original shaft it destroyed its transmission at 356 miles on the odometer and had to be towed to the dealership. I understand your frustration but with the right diagnosis the trucks can be made to function. Still we should not have to do any of this to a brand new $41,000 truck!! I did because I could not afford to trade that brand new truck back in and the whole situation pissed me off enough that I wanted to show those high paid GM engineers that it could be fixed if you said screw the corporate limitations placed on them. I’m sure they already knew that, but wanted to stay employed!!

    I took a set of 17 inch Z71 wheels from a 2005 Tahoe I used to own and went to Wal Mart and bought the cheapest Goodyear tire I could. I put them on in place of my 20 inch chromed stock wheels and RSAs on my 2017 LTZ. The ride was much smoother, I got better mpg, and they seem to last forever. 17,500 miles and no visible wear. Not sure who makes the wheels now for GM, but to me they are suspect. Ill put the 20s back on when I'm ready to get rid of the truck.

    It's still ongoing.

    Performance Drivelines out of CA made my two piece driveshaft kit for my 2017 1500 crew cab LTZ 2wd. Over 15k of silk smooth operation so far. Cost is under a grand delivered. Can be installed with a drill and normal hand tools in about 90 minutes. All steel construction and are way stronger that stock shaft.

    I been preaching this about the driveshaft for over 10 months! Glad some owners now realize I was not blowing smoke.
  10. Bart’s Silverado
    Call them!

    GM will only replace it with another aluminum shaft. They did that for me and determined that the replacement shaft was only half as out of round as my original one. However that amount was within GM specs so no replacement of the Second shaft. Mind you they had already done tires, torque converter, etc with no success. I had less than 1000 miles on it. I could not afford to trade (8000 bucks for a 2018) so I set about determining what part could be causing different vibrations at varying speeds. The driveshaft! So I contacted Performance Drivelines in Barstow CA and they made me a custom two piece steel driveshaft with a custom center support and bearing. They made it to 3/4 ton specs for my 1500. It cost me $800 shipped to my door. Took me about 90 minutes to install in my driveway laying on my back! One test drive and I had a smooth as silk truck. It now has 15,000 miles more and still no vibrations. GM knows they have driveshaft problems but to recall would cost billions. They are content paying dealer to perform their slight of hand to appease customers and buy back a few here and there. I lost my warranty on the driveshaft thru GM but at least I now have a truck I can enjoy for many more thousands of miles. I took it in for an oil change the other day and every tech came over to look at my solution. I noticed that my truck traveled 30 miles during that oil change! They drove it just to verify I was right!!!

    Cheaply sourced aluminum driveshafts made in Mexico. I replaced mine with a steel one and wa-la, no more vibration. My truck has been vibration free for 15,000 miles! GM knows but with millions of units sold it would break GM to fix them.
  13. Bart’s Silverado
    It's the drive shaft. See my other posts.
  14. Bart’s Silverado
    I've got $20 That says it is the driveshaft!!! See my other posts.

    I've said this several times. It is the style of driveshaft Chevy and GMC use on these trucks that is causing the Chevy Shake. The large diameter, long, thin walled, aluminum driveshaft are inherent wobble queens. This is why each truck has a speed limiter at different speeds. Once the shaft starts vibrating they back off a couple mph/kph and set the limit. If you can't drive the truck fast enough to reach driveshaft critical speed, you won't trash the tranny like I did. Now for the other shakes at other speeds, they too are driveshaft related. I changed my driveshaft over to a two piece steel shaft and center carrier. It is on a 2017 LTZ 2WD Crew Cab. It is also made to 3/4 ton specs. Since installing it 12,000 miles ago I have had a smooth as silk truck that will cruise all day long at triple digits if you so choose. My cost was about $900 but that sure beat trading for another brand truck. All the road force balancing in the world will not fix these trucks. Only a new style driveshaft will do it! Mark my words.

    Excellent rant Shawn, and extremely accurate. You did leave out one very important thing. Most buyers that financed a new Silverado are so upside down in their loan, thanks to the huge drop in trade in value once the papers are signed that switching brands is financially impossible. I paid over $12,000 down on a truck discounted $10,000 and when it dumped it's transmission at 357 miles I tried to trade it back in, only to be told I'd owe another $10,000 to trade up one year model.

    I used a programmer to reprogram how the converter locks up. When I say reprogram I mean I selected the economy programming for the converter. I also disabled the cylinder deactivation. I think those two actions eliminated the shudder on my truck. It may have just been the elimination of cylinder deactivation. BTW I saw no decrease in fuel economy by eliminating the cylinder deactivation and returning to a true V8 engine. I am enjoying more power under my right foot though!

    They make custom driveshaft setups for raised and lowered trucks where driveshaft critical speeds or clearance issues can easily become a problem. Adapting their technology to standard ride height trucks was an easy issue for them. I've had great results. I'm the one that actually figured out that the driveshaft were the issue, they just supplied me with my desired solution.
  19. Bart’s Silverado
    Your driveshaft continues to turn even in neutral, so if the vibration is in the shaft it will continue to vibrate in neutral. They make money off tire sales and usually with no return policy. I have Nittos and they are no more smooth than any other tire I've tried. Want smooth, go Michelin. Better yet, go with a new driveshaft.

    It will wind up being the driveshaft. I replaced mine with a 2 piece steel driveshaft from Performance Drivelines and I have a very smooth riding 2017 Silverado LTZ. Love the truck now! Best $800 I ever spent. Hate that GM is too ignorant and too cheap to actually fix these trucks.
  21. Bart’s Silverado
    You are just throwing your money away. Please see my other posts. Your problem is driveshaft related. Get rid of that long fat aluminum driveshaft. Go to a two piece shaft if yours is 2wd or a steel replacement shaft if yours is 4wd. I recommend you look up Performance Drivelines in California.
  22. Bart’s Silverado
    Buy a programmer and program the converter for hyper mileage or economy. See my other posts for more info on riding smooth. I'm satisfied with my Silverado now but definitely will never buy a GM truck again. Corporate is not interested in customer satisfaction at all. If they are they can call me at 931-675-1161 and we will discuss. Bet all I hear is the wind!

    The vibration is in the aluminum driveshaft. I replaced mine in my 2017 LTZ 2WD with a steel two piece rated for a 3/4 ton truck. My truck has been smooth as silk at all speeds ever since. I'm approaching 10,000 miles on the driveshaft. Cost was under $800 from Performance Drivelines. Look them up and leave the Chevy Shake behind!
  24. Bart’s Silverado
    Try replacing the one piece driveshaft with a two piece shaft from Performance Drivelines. I did and my truck is smooth as silk at all speeds. Re-tuned it can reach triple digits with ease and is smooth there as well. I was ready to trade till I figured out the problem. Now, it's a perfect truck!
  25. Bart’s Silverado
    UPDATE: After over 6000 trouble and vibration free miles I think I may have really found two main causes of the Chevy Shake. It is the very long aluminum driveshaft and the 20 inch tires. Just replacing the shaft took out 90% of the shake. Going back to a proven 12 year old set of 17" Chevy Tahoe Z-71 wheels with brand new tires took care of the rest. I hate that I had to spend $2,000 to fix a new $40,000 truck but with absolutely ZERO help from GM, I could not afford to do otherwise. Truck is approaching 9000 miles. Ill check back in at 15,000.
