    Hi, have a 2015 dd13 cascadia. Making a rattling type loud noise when engine is under load. Weird part is it seems to resolve itself or get better when I do a parked regen. Anyone with experience with this? Thanks

    Gotta grease that muffler bearing!!!
    What rpm range is the rattling sound happening at? Have you looked at your exhaust system, clamps/mounts? Has anyone worked on your one-box, the heatshield around them tends to rattle when reinstalled without new bolts to replace the old broken ones.

    The more backstory on your truck and details on how or when the issue occurs, the more likely someone can offer helpful advice. But seriously, next time you're getting an oil change let the shop know to grease the muffler bearing.
