yea vehicle vin is what i was asking the last eight digits have something to do with it because thats what the dealer asked me for when i called. mine is going out i think got on it hard one day heard a pop and now when u let off the gas u hear a clink like u joint bad then growling sound like teeth are all most touching but not making full contact as u coast hit the gas and that sound goes away but there is alot of play when u tap the gas before u feel the power to the wheels like as if u put it in first and hit pedal let off hit again type thing u dont get that sudden burst of exceleration it is lagged due to something. im going to tear it apart and look but i think its done worn out or something broke, <img src="/forums/images/graemlins/patriot.gif" alt="" />
