shaking from front tires
My GMC truck has new tires.Balanced and alignment.But it has started shaking very badly like i have a flat front
tire.If i pull over and stop then start moving again it drives fine then it will happen again. Does not matter what
speed im going and it is not constant.It might happen twice a day or once every couple of days but it is happening
more often and then shaking is getting worse.Any suggestions as to what it might be?
