Amccutc21 Posted January 12, 2018 Share Posted January 12, 2018 I picked up another Comanche tonight and as the title says, it has a loud squeal. It is a 1988 4.0 2-wd automatic. The squeal gets louder as RPMs go up. From what I’ve read on here, my first thoughts are the harmonic balancer. Will I be able to tell by looking at it visually or just replace it and hope it fixes the squeal? Link to comment Share on other sites More sharing options...
HOrnbrod Posted January 12, 2018 Share Posted January 12, 2018 It might be the balancer, or it might be one of the pulley bearings turned by the belt. Pickup a mechanics stethoscope (below) or use a length of vacuum hose with one end stuck in your ear. You should be able to ID it easily. Link to comment Share on other sites More sharing options...
Green Mesa XJ Posted January 12, 2018 Share Posted January 12, 2018 X2 on the stethoscope. I’ve had a belt pulley make a intermittent horrible squeak. Did it at first only when it rained, I thought it was just the belt.Cheap Chinese bearing eventually locked up.

Amccutc21 Posted January 12, 2018 Author Share Posted January 12, 2018 Just purchased one from ebay, thanks! Link to comment Share on other sites More sharing options...
kryptronic Posted January 12, 2018 Share Posted January 12, 2018 Check to be sure the belt is routed straight as well. I had a similar issue where lining up the pulleys better cured it. Link to comment Share on other sites More sharing options...
Amccutc21 Posted January 12, 2018 Author Share Posted January 12, 2018 I'll check that out whenever the weather breaks, thanks! Link to comment Share on other sites More sharing options...
Keyav8r Posted January 12, 2018 Share Posted January 12, 2018 If you want to check your balancer, I have photos of the bad one I pulled from ‘88 and the new replacement. PM an e-mail address and I’ll send them to you. Link to comment Share on other sites More sharing options...
