Folks, my saga began in Sept of '14. I loved my new Silverado 1500 WT until I hit the interstate. Vibration at 65 mph. My dealer balanced and then changed tires and rims, no difference. In December my truck was sent to a second dealer who rebalanced the tires and said they were way off, they checked the rear end and axels and finally replaced the drive shaft because it was out of round on the inside.
When I drove it i didn't know if the 65 mph shake was gone because from 15 mph up it felt like "Magic Fingers". Both dealers and the GM rep pronounced it good and I screamed lawsuit.
I finally noticed the red dots on the Bridgestones were all over the place. After a heated discussion with the GM rep about them refusing to correct obvious improper installation I convinced them to remount the tires with the red dot at the valve stem as Bridgestone requires. This was done Jan. 28, 2015.
I am now the owner of a fine-functioning new truck.
It took 2200 miles and 45 days in the shop and I had to lead them by the nose but it worked. I'm just sad that I didn't get to enjoy that new truck smell.
