64 Cheyenne Posted April 9, 2009 Posted April 9, 2009 Am I correct in thinking that my harmonic balancer is bad if it is hitting the timing cover on this It's an 89 with a 4.0 Tried to take picts You can barely see where the balancer is hitting the cover in this pic. Or is it possible that it has other problems. Is there a possibility of,I think I read about in another post, thrust bearing ? problems. The rubbing hasn't gone all the way through the timing cover (I know it's toast), and there isn't any oil coming from the rear main seal.
BBCchris Posted April 9, 2009 Posted April 9, 2009 Yep, its on its way out. The outer ring is seperating from the rubber part.
88 Beast Posted April 11, 2009 Posted April 11, 2009 :agree: It's a fairly common issue. x2. Same thing happened to me. Sounded just like an exhaust leak. Luckily I spotted it right before tearing into the manifold :banana: Easy to replace and cheap too. Just make sure you use balancer puller and installer. DON'T use a hammer.
