I have a 1995 ranger 4.0 engine V6 and it recently just began squeaking. I had the problem a few months ago before the truck broke down. It wasn't too severe then, but I just replaced the starter and it began working again. Now that it's fixed, the squeaking is worse than ever. It used to be where I could drive it for a few miles and the squeaking would quit, but now it is non stop and gets louder as my rpm increases. I have a brand new duralast belt on it and I've sprayed wd40 in some areas. I have no idea what else could be the problem. Pulleys? Any help would be appreciated. Hopefully it won't be too expensive to fix it. If you could leave an estimated price I would appreciate it. Thank you.
