This week will tell, I'll be driving to and from work 70 miles one way on several different pavement types will see how this combo (tires and shocks) plays out. Yeah never really expected this truck to drive like a car and probably my fault for not paying more attention when buying it. Should have known that a used 2014 with 6k on it sitting on the lot had problems. I will let everyone know how is goes after a few days of break-in.

Really don't know what to say to that except BS. There is something seriously weird with the way it vibrates. Not just a tire vibration almost like the shocks aren't dampening the vibrations. Going to invest $400 in the Bilstein 5100 has the stock Rancho's on it now. Well its been 3 months but I received and installed the Bilstein shocks and Michelin tires for my Silverado. "Problem solved" What a difference those shocks and tires make. Totally different feeling truck. Adjusted the shocks to the highest setting and now with a full tank of gas the front and back are the same height and no more vibrations. Worth the $1400 investment.

Well got my truck back on Tuesday and pinion and ring gear were replaced along with the the tires being road forced balanced. The vibration at 40 to 55 is gone and now vibrates at 65 and up. Taking it back on Monday to redo the tires, hopefully this will fix it.

Should have did a little more research before buying this truck but hopefully Chevy can fix it. Going to drop it off today. I’ve driven the truck approximately 1000 miles on all types of roads. From 40 to 55 the truck resonates (vibrates), especially when decelerating, and going downhill. The more you drive (warn up the vehicle) the worse the vibration seems to get. I can feel it mostly through the steering wheel but can see the dash and center console vibrating in the truck when it’s really bad. I say resonate because it doesn’t seem to be the tires although I really can’t tell. Never had tires vibrate like this before. When driving highway speeds 60 to 75 the vibration is less noticeable (tolerable) but still happening. Almost seems like the driveshaft is out of balance or a bearing is going bad. I've read through several reples and different sites has there been any specific cause for this problem or is it different for every truck? 2014 Chevrolet Silverado Z71, LT Extended Cab, 5.3L, 7k miles
