I’ve had my intermediate shaft replaced twice now as well. I saved myself a trip to the dealer today and took out the shaft and greased the hell out of it. I also put an o ring over the gap on the shaft to keep the grease in. The noise and clunking has gone away for the time being. I’m going to wait for the upgraded part to come out.
I’ve had my intermediate shaft replaced once at 6000km and now at 8500km its clunking again at low speeds. Definitely hoping for a recall or support from the aftermarket because man it’s annoying.
