I have a 6inch lift on mine and the front to back angle never changes unless im at 10+ degree's. the rest works perfectly fine.

Update. After 3 weeks of my truck being in the shop and 3 trips back to the dealership where they put on new rims and tires and said the problem was fixed then i test drove it and said i will not accept my truck back in this condition they found of my rear axle is 8 degrees off. they ordered shims to correct this issue and we will see in a few days if this fixes my vibration issue.

currently 19500 miles. 1st took it in for a Tire balance because of shaking around 2500 miles. I didnt know about the Chevy shake till about 10-12k miles

They said they felt it to and to just keep the rental truck (2016 silverado shaker) till they call me saying its fixed. Also something i found very interesting is the main Manager said CHEVY sent him to a shaking class last week 0_o. maybe they are starting to take this problem seriously

They installed the lift so it would still be there responsibility. I had the dealer put stock tires on my truck and test drive it. They said the problem is fixed i said wait to change the tires till i get there. I test drove my truck with stock tires and still had the same exact issue. My truck is now at 4 wheel parts and my friend called me to say he checked out the truck front to back and everything is perfect and he even checked the balance of my drive shaft which he said was good. Now my truck is going back to the dealer to sit for a week before they tell me my truck is fixed again.

2015 Silverado with a stage 2 procomp 6" lift. My truck has been to the dealership 10 times for shaking. now after 2 weeks at the shop they are saying its my wheels because they cant find anything else wrong with the truck. i have had 2 rental trucks both 2016 1500's one was a work truck the other was an LT and they both shake. The dealer is now saying they will not work on my truck again till i replace all 4 tires which will cost me $1600 they also informed me i have to take my truck back once i have new tires if the shaking continues then they will talk about buying the truck back. I know its not the tires so i dont want to spend 1600$ but at this point i dont know what else to do. I have taken it to all 3 local dealerships and they all say i can only have it serviced at the dealership i bought it from which i know is 100% bullshit.
