I have an 05 Chevy Duramax with a manual 6 speed transmission. The last load of hay I hauled, I noticed while the truck was idling in neutral, the gear shifter started flopping from side to side with a rattling noise coming from the clutch area. When I depressed the clutch, the shifter stopped flopping from side to side and the noise went away. Never done it again until a few days later. The second time was after hauling a load of lumber, this time when I pressed the clutch the flopping and noise didn't stop. I actually had to put it into gear and let out on the clutch a little putting pressure on the drive line for the flopping and noise to stop.
I checked with a local diesel shop about a possible clutch/throw out bearing/idler bearing failure as the possible culprit. They had stated they have seen this scenario on other bigger trucks and ended up being a bad fuel injector. Now the truck runs fine, no misses, hiccups or smoke at 170k miles. If it is an injector wouldn't there be other indicators like hard starting or a miss while idling or under a load? If it is within the clutch area, is it a dual disc clutch assembly? There is no chatter or unusual feeling in the clutch pedal when depressed.
There is no whine when driving the truck like it could be a front housing bearing. No chunks or large debris in the oil or on the magnetic plug.
I'm curious if any of you have experienced a scenario like this because I don't want to just throw money at a hunch.
I'm heading home in a few weeks and want to tackle this job while home on R&R.
