New to the forum. I bought a shaker! uhhh
I bought a 2016 crew cab 4x4 5.3 6 speed 5.5 bed sierra. It vibrated as soon as I got on the highway (10 miles on odo). I brought it back the next day and they replaced a tire and then said the vibration is within spec. I noticed it still vibrates at highway speed, but I'm rarely on the highway. I replaced the rims and tires with a winter setup and the vibration is exactly the same, so its not the tires
I went on a 600 mile highway trip last week and the vibration comes and goes at around 70mph+. Back to the shop it goes. I wouldn't have bought this truck if I test drove it on the highway. I can't believe gm would sell a truck that rides like this and the service dept says its ok! luckily I got it during the 20% off sale on labor day, so if it comes down to trading it in I wont take a huge bath
