I said 2011 and he said this thing only goes up to something like 2006 if I remember correctly. The boss man there said just use that they are all the same. Is this true? I read somewhere that 2007 through current year is all the same but 2006 is an entirely different suspension. Are there certain specs for my 2011 that I can give him to plug into his alignment machine? I swear this truck now sounds as if the tires are sure making more noise than ever before, not sure if its in my head.
