I've heard that the chronic timing chain rattle for '01 and '02 4.0 SOHC's was fixed at some point during '02. I've searched the internet and the forums and can't find any hard data that tells me which trucks are affected or not. Does anyone know of some dates of manufacture or perhaps a resource I can run a VIN through to see if the truck should be fixed?
I'm in the process of buying a new truck and am looking at an '02 4.0, but don't want to have to deal with the timing chain issue seeing as how they are now out of warranty.
Thanks for any help.
