Alright so I have 2009 Sierra Crew Cab, with 5" RCX lift (4.5" rear blocks). Sometimes when I'm on dirt roads or really loose gravel and I'm spinning the tires and my foot is to the floor. My rear end will start to shudder and shake, this only happens once and awhile. Other than that the truck drives perfectly fine, no vibrations, nothing. I'm thinking it's an axle wrap issue? but can't confirm. If it is, what are my potential solutions, will add a leaf help fix this?
