As HLS mentioned, her 2002 4.7L came through a 16T ton ring top top the crank and also the correct equivalent tone ring on the Passengers side camshaft. The 2004 4.7L came v a 32T ton ring on the crank v a camshaft ton ring details for that application. 1999-2002 = JTEC PCM 16T ton Ring2003-UP = NGC PCM 32T ton Ring. Its vital to note that the camshaft tone rings are different as well and also you must use the suitable tone ring because that the PCM the engine will certainly be to run in.In stimulate to run the 2003+ engines in a later 99-02 vehicles or vise versa you have to insure you have the suitable tone rings installed. Speed SAFE, NICK

Thank you because that the info. Yes so to swap out the ton rings would certainly I have to pull the motor ago out of the van or is there an less complicated way? What around the crankshaft placing sensor and camshaft sensor would they jave to it is in changed?
s would certainly I have to pull the motor back out the the truck or is over there an easier way? What around the crankshaft placing sensor and camshaft sensor would certainly they jave to it is in changed?

WOW... Late post, and also hopefully you have actually fixed your problem by now... Yet for future reference and also others with similar questions... The quick answer is YES. Friend will should remove the engine to readjust the crankshaft tone ring. Timing set would should be removed and reinstalled once completed... For this reason its no a difficult job, simply time consuming... Quick & easy if the doner engine is already out that the vehicle and on a stand.If the engine is installed into the auto like her is, Its actually a large job due to the fact that the crank needs to it is in lifted high sufficient out the the block because that the ton ring to it is in removed and also replaced. In most situations this method you must remove the 4 aft pistons and also rods then tilt the crank up. BE an extremely careful not to pull any of the pistons out from the bottom to the suggest a piston ring come out... If a piston ring comes out, climate the only method to reinstall is is v the top... An interpretation that the crank needs to come every the way out and to make that happen all of the rods/pistons have to come out. So take your time and position the pistons as much INTO the feet as possible so as you progressive the crank the rings perform NOT acquire exposed.With all that said, (NOT my RECOMMENDATION) I have actually heard of human being doing this procedure v the engine mounted without taking any pistons out... Yet this still calls for the front timing cover needs to it is in removed and also timing chain/gear need to be significant to insure they do not come to be divorced throughout the procedure. You will should pay an extremely close attention to piston ring locations and also insuring girlfriend dont allow ANY come pop the end from the bottom the the cylinder.... If a ring comes out, then you have no option and need to traction the engine...If you attempt to reinstall the piston and ring from the bottom, friend WILL damage the ring... For this reason dont even dream about it. For this reason you can roll the dice... It will either conserve you time or twin the time. Rate SAFE, NICK.
