There are several potential causes for differential noise in the Mercedes-Benz Sprinter, and the exact nature of the sound typically indicates its source. You might describe the noise as "whirring," "whining," "rumbling," "clunking," or "clicking," each pointing to distinct issues. For instance, a whirring noise while decelerating often results from failing pinion bearings or a loose pinion bearing preload, but it could also be due to worn carrier bearings. If the noise is a whining sound during acceleration, it's likely caused by worn ring and pinion gears or an incorrect gear setup. Clunking may suggest a broken ring or pinion gear tooth, similar to clicking. Additionally, if you hear clunking or clicking, especially when starting from a stop, the issue might be loose yokes, bad u-joints, or a worn transfer case.
If your Mercedes Sprinter's differential is leaking fluid or making grinding sounds when you turn, it might require fixing or replacing. On the other hand, "whirring" noises from the differential could indicate problems with worn-out or loose pinion bearings.
