how do I know if my new 03 had the seats TSB done already?

[richardyc]

just picked up my 03 sport edition v8 4runner yesterday, and my seats don't squeak YET, maybe they have performed the TSB when it was sitting on the dealer's lot (I somehow doubt that dealer would go out of their way to do TSB fixes on unsold cars, but who knows) so how do I know if my truck has the fix in already? Can someone post a before and after picture?

Did anyone feel the "roughness" when the engine is at around 1700-1800rpm? Is this what the lexus gx470 people are complaining about?

thanks,
Rich
