MY TURCK MAKES A RATTLEING NOISE AT AROUND 2,700 RPMS, I CAN HEAR IT, FEEL IT IN THE PETAL, AND GETS LOUDER THE HIGHER THE RPMS GO. WHEN YOU START FAST FROM A STOP YOU DO NOT HEAR IT IN FIRST BUT WHEN IT REACHES SECOND THROUGH FOURTH YOU CAN HEAR IT AND FEEL IT. ALSO WHEN YOU START THE TRUCK UP WHEN ITS COLD IT HESITATES FOR A LITTLE WHILE UNTILL ITS WARMED UP THEN IT STILL HESITATES FROM TIME TO TIME. WHEN THE RPMS REACH 3,800 RPMS IT BUCKS A LITTLE THEN FINALLY SHIFTS INTO GEAR. IT READLINES AT 4,500 ITS A 4.0 LITRE v6

Ok lets first take it one problem at a time. First the vibration. Have you checked the u-joints on both front and rear drivelines? Then have you checked the front axle joints? Have you checked for wheel play with the front wheels off the ground? If all this is good then check the tire balance and rotate them. Let me know how it goes.

Yes the front u joints are all greased up and one side is completely new. The tires are only about a year old with about 16,000 miles on them. They are rated for 50, 00 treat warrenty. What about the hesitation I get from the engine when it is first started up? The fuel filter is has only 15,000 miles on it. It happens when the truck is cold right after you start it up and it happens when I try and pass someone.

Ok I would still balance and rotate the tires as tires should be rotated around ever 6,000 miles unless they are off road or mud tires then I recomend every 3,000. Now as for the hessitiation I would get some mass air flow cleaner (nothing else) and clean the mass air flow sensor. The mass air flow sensor is mounted on the air cleaner housings. Just simply remove it and spray it out then put it back in. Let me know how this goes if it don't fix it then I want to test the TPS and for that you will need a digital multi meter. Let me know how it goes.
