ive got a 99 ranger with a 4.0 and i would like to know what can be done about the loud ticking?? i know its the rockers, but im confused???? ive been told its the push rods, the rocker arm shafts, lifters, but if it was the lifters it would have a skip ? i found a company that sells rebuilt shafts and they want the old shafts back as a core, so are they just replacing the rockers and using the old shafts?? they also supply new pushrods as a kit. can anybody tell me the cheapest way to correct the ticking or is there anybody out there that knows where to get the parts? the co. that sells them says that they are out of stock, and going to a junkyards a crapshoot but??? let me know what you think maybe someone has a set that they didnt use??
