I can't hear a problem, it sounds like normal driveline lash. Assuming of course that you're shifting from park to drive or reverse to drive. I haven't listened to my truck from that vantage point though. If it worries you and still under warranty get the dealer to check it out. If it isn't under warranty bring it by a local repair shop and ask if a tech can have a listen in the parking lot.

Doesn't the "clunk" sound seem excessive? I expect there to be lash, obviously, but the clunk doesn't make me happy.

 

I should note that I have a "howl" noise when I am coasting, it goes away when you give it some throttle. Only seems to happen when the diff is fully warmed up.

The clunk sound normal to me. A howling noise as long as it isn't too loud could be considered normal as well. There is a lot going on in the driveline. I would mention it when you take it in for the oil change. You may ask if a service manager or foreman to come for a ride. I had them do this for a torque converter problem in my 1500. The foreman wanted to drive and I insisted to be there to explain how to cause the condition. He drove, I explained what speed and load to be in the problem showed itself and the repair was done without multiple visits. You should try this to satisfy yourself if there is a problem or not.

Yeah I've got a few ideas. First, I'm going to take a better video with a light. Then, I'm going to do the same exercise with my 72 K10 and see how much movement and noise I get on the old one. Might even use some chalk to draw a reference line from the yoke to the axle housing to see how much movement I get in each case.

 

When my oil change comes due I will bring it up. I also want to make sure I can duplicate the noise, it appears to only occur when the driveline is fully warmed up.

I have 1300 miles on my 17' and also notice a noise when decelerating, somewhat of a gear whine. It is always present when decelerating but more noticeable at higher speeds. It seems loudest around 55 mph when off the gas. Have others noticed this? I see the OP has.

My tranny and rear end were horrible when new, now with 14k it is fine. Just normal break in.

Did you ever come up with anything from the howl noise? I have a 2018 doing the same thing. Dealer has and is replacing the rear axles??

I think I was being oversensitive.  I have about 35k miles and havent thought about it in two years.  Not saying your situation is the same though!

      Cold start Miss, oil in cylinder

      By newdude · Posted

      Its coolant disguised as oil.   TSB - 20-NA-166 1..3   "To inspect for this concern, add coolant dye to the system, run the engine through warm up, pressurize the cooling system after warming the engine to operating temperature (let the engine cool overnight) and inspect the suspect cylinder with a borescope for coolant dye evidence. At times it may be necessary to remove the head for inspection. If the head casting line is the concern, the intake port will be wet with a coolant oil mix"

      Can you sample the pooled liquid, enough to confirm it is oil?   ...That its not fuel or coolant.   Also, make sure combustion gases aren't entering the cooling system.   Simply put, either oil being pushed up past the rings (this really isn't possible), oil leaking past the head gasket, oil leaking past the valve, oil entering through the intake air path. If none of this is likely - it may not be oil.   What could be likely is the fuel injector leaking down. A puddle of gas would still smoke and rough idle. (Same cylinder has the same problem after injector replacement?)   What is the crank time first thing in the morning, when the puddle would be present? Does it seem like the high pressure fuel pump needs an extra second or two to rebuild the pressure that injector 8 may have let bleed off? Check the fuel pressure via a scanner prior to starting the engine.

      Good information!  I didn't know about the dementia aspect and asked for a general for my second knee. I'd heard that recovery room time is usually shorter with a general.   The anesthesiologist talked me out of it and I had the spinal.  Inconvenience and/or discomfort is a small price to pay for reduced risk!

      This is for those over 70 years of age contemplating joint replacement surgery involving general anesthesia. Even some 55 yrs. ago when I took my pharmacology class the dangers of developing dementia in the elderly that had general anesthesia were beginning to be recognized. Over the years there has been some refinement in the cautionary warnings, avoid general anesthesia if possible if you've had close to 10 priors, especially over the age of 70 and/or a family history of dementia. I'm not including the twilight anesthesia induced by propofol often used in cytoscopies or colonscopies. Seriously think about seeing a neurologist and undergo cognitive testing before proceeding if any of those criteria apply to you. Spinal anesthesia may be an option in some cases. I'm in the above camp and although I could use a new right knee, I get fidgety according to a prior orthopedic surgeon when the bone saw spools up or maybe it was the smell of saw blade meeting bone, anyhow I may have one general anesthesia left in me which I will pocket for now and I'm choosing mind over mobility, anyway where did I leave my damn cane!
