Just purchased a 2019 lifted Onward. I heard the rattle at purchase but figured I can figure out the trouble and the price was right. It sounded like a heat shield rattle (exhaust). It’s a very tinny sound and fairly loud. Not noticeable at idle or when on Jack stands. I took video through the back hatch and did not see anything vibrating but the sound did seem to be coming from the drive or driven clutch. I’m leaning more towards the driven clutch 1) Cause the noise seems to be more pronounced there 2) The drive clutch had sharpie writing (illegible) on the cover and it didn’t look factory leading me to think it may have been changed already. Oh, The sound is more pronounced w/ load/speed.
