I have a 2018 Z71 Silverado LT. I notice a vibration through the steering at speeds of 110 to 120 km per hr. The truck does not always do it but when it does it is very annoying. Does anyone know of a fix?
You are still in the warranty period so why ask on the web. Or it could be as simple of having the tires balanced and rotated.
Tire balancing is considered as adjustments and is generally only covered for 12 months/12,000 miles, that is why people ask for advice on the web.
This is pretty much the speed at which you would notice tires that need to be (re)balanced
