Differential Noise Failure Analysis, What Causes Noisy Gears?
Differential Noise Failure Analysis, What Causes Noisy Gears?
Those of you that have been following the #ETCGDadsTruck series know that I had a noise coming from the differential ever since I rebuilt it. I’ve since solved the problem with a new set of gears, but I decided to send the noisy gears off to be analyzed by a professional. In this video I share the results of that analysis and also talk about how you can avoid gear noise when rebuilding differentials.
