    2018 Silverado 1500 W/T Long Bed
  1. Shake or Vibration Issues

    Will post back in about 2 weeks when I get the new tires
  2. Shake or Vibration Issues

    New member here--Just bought a new 2018 Silverado 1500 W/T model regular cab long bed. Got on the highway to take it home and it immediately started vibrating at about 63 mph and above,felt it in the steering wheel and the center console module. Doesn't always do it at that speed depending on the road surface texture but it does it more than half the time. Took it back in for service with about 200 miles showing on the odometer and they road force balanced the tires and told me to put a couple hundred more miles on it in case the tires needed to round back out from sitting on the dealer's lot,it was manufactured 3/18 and it has General Grabber HTS 255/70/17 tires. Service writer said if there's still a problem call them and they will order 3 new tires. I asked him why only 3 new tires instead of 4,doesn"t make sense to make sense to me. He said that 3 of the tires were near high end of limit but 4th tire wasn't and GM won't let them order it. Also looked like they had one of the "junior" mechanics working on it. I've put 250 miles on it since and there's still a problem so I'll have to call them and tell them to order the tires and probably have to argue about getting the 4th one. I've read the last 20 pages of this thread so I'm not getting my hopes up that new tires will solve the problem. Any suggestions on how to deal with this if the new tires don't do the trick? Also noticed that extended or crew cab models seem to be mentioned the most in the pages I've read. Does this problem seem to crop up in the regular cab long beds much ? Other than the vibration problem the truck is pretty much what I've expected for a low end trim model. Thanx, bumtruck ;
