What shake issue are you speaking of?
Are you talking of the TCC shudder?
If so, there is a TSB that covers that with a transmission fluid change.

Sounds like pinion angle and tire problems. For me, I've got my pinion pointed .5* lower than the t-case and then I've locked that in with a set of RC traction bars. It's shocking how sensitive this truck has been to pinion angle. If it's off by just a couple degrees you'll get vibrations at different speeds. When mine was 1.5 degrees lower (stock setup) than the tcase it vibrated pretty bad between 57-65.

Did it solve it ? Thanks 

Near as I can tell it did. The only speed sensitive vibrations I get are between 78-84 MPH and  I think that's driveshaft related now, but still could be my crappy tires (lots of weight to balance is usually indicative of a bad tire). All in all, it seems like these frames are very sensitive to NVH. Everything comes together. Can't say 100% it's because I corrected the pinion angle but it certainly played a role. Next up for me is a better front suspension setup - then tires. I imagine by then I'll be very happy. 

 

Far cry from when I picked it up in Houston and drove 4 hours home. It was pretty bad and made me regret my purchase. Road-force balance the tires, new/slightly better struts and shocks, and Roadmaster active suspension combined with traction bars, and biggest of all - custom tuning have made it drive a lot different.

Glad that you are almost there and some what better , mine is in the dealer now for diagnostics, all of these post I’m reading watching makes me think that I may have to go couple of times back fort and fight with the dealer my biggest fear Is they gona tell me what everyone already knows step one trans oil flush with mobil 1, step 2 force balance ,step 3 drive shaft balance m, step 4 new wheels tires , I maybe over thinking it ,  I’m hoping it gets fixed. As I don’t have the recourse with time and money out of pocket. I have power train warranty October 2022. 
 

note: I have not Owned a pick up truck before 

Nor bought a car in a while All I know is I wanted a pick up for while I waited saved up for 15 years to afford it now this ... 🤦🏻‍♂️ smh

Welcome to this forum!   The Chevy shake story is covered extensively in this forum and you will find a lot of potential causes and solutions to the shake.  .  I have experienced a few shakers (not all GM) in my life and the cause has always been a tire/wheel related issue.  Your problem can be as simple as a wheel weight falling off.  Don't overthink the issue or start replacing parts until you've tried the simple fixes.

Another possible fix is to move the tire; front to back or can also try L to R after that. Does your truck have a lift kit installed or is it stock? What make of tires? what wheels? factory or after market?

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
