Hey all. Seeking some help on what appears to be some driveline vibration. 2019 Silverado LT Double Cab. 2” level front level. I attempted to install 1” rear blocks to get some rake back. Had some bad vibration and immediately uninstalled the blocks. Torqued everything back to spec, but the vibration has remained at highway speed or when accelerating over 2,000 rpm. The truck does have the factory shims. Anyone have any input on what might be causing the issue or your operating angles for reference?
