mlkrguy Posted January 13, 2018 Share Posted January 13, 2018 Check the exhaust stack mount on the cab. Our new Ganites rattle at that point. We spray some white lube on them and it quiets them down. Quote Link to comment Share on other sites More sharing options...
james j neiweem Posted January 13, 2018 Share Posted January 13, 2018 Some times these rattles can be a resonance issue. Have someone sit in the cab and slowly run the engine rpm up and down. Have another person outside listen for rattling sounds at different rpm's. Resonance will usually be a higher pitch buzzing sound and will occur at a specific RPM or range of RPM. When found tighten, lubricate or shim. Rattling in the rear end would more likely be more of a clunking sound. Camel backs will rattle but usually after thousands of miles of wear on suspension parts. Quote Link to comment Share on other sites More sharing options...
