My 25' Custom has a sound, that's not what I'd call a rattle, but more of a scrubbing sound that comes from the driver's side, passanger door, on the inside. Forward, and up from the door handle, if that makes sense. Sounds like 2 pieces of soft plastic rubbing against each other.

It's right behind my left ear, if you're driving. 

Anyone else?

Not related to your problem, but about a month ago I started getting a fluttering noise in mine. It kept getting worse. I decided it was definitely speed related. Being basically lazy in my retirement, I ignored it. Took a trip with my noise sensitive wife. That upped the priority on finding the problem. Got about 30 miles when I decided it would need immediate attention or I would have to listen to it and my wife. 🙂 Stopped and started checking. Turned out the hood deflector had worked loose on one side. Bought some foam tape and inserted a piece of that. Problem solved.

Not precisely what you are referring to and not of any help, but...

 

I get a fluttering type of noise that sounds like it is coming from the front console / behind dash, driver's side area.  It happens intermittently and only when traveling approx. 20mph or faster, and again, not all of the time.  I don't what it can be.

This might be that loose bolt on the coolant reservoir. Pop the hood it’s on the drivers side fender near firewall. That bolt is loose on a lot of trucks. 
presented as a weird flutter sound going over bumps lower speeds. I tightened mine and no more noises.

I'll be darned.  Not that I have any noises but decided to check the reservoir bolts after reading your reply, they both were loose.  You da man @Pryme!!

Not your issue but I have a good one. I had a 2001 Silverado that developed a sporadic flutter at speeds above 60mph. It really annoyed me (because I couldn't find the cause) but it drove my wife crazy. Which in turn aggravated me even more. One day while driving I leaned forward to find the source and noticed it was the rubber cover over the hood hinges under the cowl panel. I guess the bug deflector on the hood contaminated the air flow. I replaced the rubber with a heavier piece and solved the issue.

Pryme, I checked mine and it was loose!  The side mounted bolt was very loose and the second vertically mounted bolt slightly loose.  I tightened both.  Time will tell if this was the fluttering sound I was experiencing.  Thanks for the tip!

I bet it is. Mine did it and when I tightened that up it was silent. That reminds me I might just check it again just to make sure those don’t have a tendency to back out. Still no noise

Update....It's been over two months since I tightened the bolts on the coolant reservoir....no more noises (at least the one I had)!

Thanks Pryme for the tip!

      Oil Consumption

      By diyer2 · Posted

      I have changed oil and filter for years by starting a cold engine to warm oil up, let it run 5-10 minutes depending on temperature. Drain until it starts dripping, refill with quantity from owners manual or get it close.

      Fluid Change Questions

      By Chuck FB · Posted

      I changed the factory fill oil in the rear diff of my truck for the first time today and the miles is close to 9000 on the truck. There was a lot of fines on the magnet, a very thick layer but working it through my fingers it all felt like mush and as most know it appears like graphite, so no surprise chunks anyway. Certainly was time to do it from my thinking and could have been done sooner but the oil didn't look awful but sure wasn't new looking and never expected it to either. I did use some solvent to help me clean out the bottom area of the axle housing, just get any other stuff settled at the bottom washed and wiped out of the housing for the bit of effort it takes. I used Amsoil Severe Gear 75W90 in the easy packs to try out what they are like and I used up 4 packs and didn't spill much at all in the process but did take all four of the packs and go to the work bench and emptied them into a measuring container and there certainly was some in them that added up to something, then poured that into one of the easy packs and squirted in what I could get out of it. I would say the level is within 1/8th of an inch of being level with the threads at the fill plug so just the perfect amount. Once again, more than what GM says the fill volume is but computes with what others are adding to their rear diffs as well.

      Oil Consumption

      By Chuck FB · Posted

      So speaking of oil consumption with my L8T as I just changed the oil yesterday and made the switch over to Amsoil SS 0W-40 from the Mobil 1  5W-30 Truck and SUV I just dropped out. 2900 miles on that oil as well as  68 hours on that oil ( so used to equipment with an hour meter and that becomes valuable information to compare with others as well ). Once again the oil use was so very little, I am going to say it dropped under 1/16 of an inch on the dipstick. No towing was done and this interval was from early spring until now.    One interesting item to note is that going by the 5 quart jugs I was using before from Mobil, it was showing that I was putting in 8 US quarts to bring it to full if not slightly over the full mark according to their jug markings. Granted I did allow more drain time this time and in part because the engine oil was only lukewarm as I started it and let it idle and not for long enough to get the oil itself hot ( the engine was up to operating temp ). The oil in that state just seemed to take forever for it to drip out but not only at the drain plug but at the oil filter housing as well, perhaps I had never quite gotten all the oil out before and I could have still waited longer but as it was I waited well over 3 hours. I think next time if I have the time I will do an experiment by dropping the oil and lets say leave the pan under it for 15 minutes, then switch to another pail and let it drip out overnight and measure how much more oil comes out. So this time and yes I ended up getting it just over the full mark as I was experimenting with trying to get the level to the add mark after I had run it and then waited some and then added a bit and waited for a certain amount of time for it to settle to the add mark. I very well may not have waited long enough for that experiment but I got to the add mark, then dumped in a full quart and waited some and checked and then waited some more and it crept up more ... and then finally oops, it was slightly over full some hours later when it really had settled all it would. I find this engine sure takes time for the last bit of oil that gets poured in to finally make its way into the crank case. I can only guess at how much too much I added as per maybe a 1/10th of a quart. I had poured in 8.5 quarts going by the quart containers as per 8 quarts and 16 us ounces. I was shocked at how much this was off compared to the prior oil changes and if those larger jugs and they are not marked accurately enough or they contain slightly more than what they say, or the drain time factor made that much of a difference. But I know on this forum there have been others who have said they have put well over 8 quarts in their L8T and now I have also going by the Amsoil true quart containers. Its a confusing convoluted mess up here in Canada with some oil manufactures packaging is in true US quarts, some is also in true US quarts containers on an even number of quarts but also marked in liters which becomes the odd ball volume of a fractional amount of liters. Then there is the Liters only containers, no US markings as its a true metric container and only measured in Liters to an even number of Liters. But remember we used to have Imperial Gallons and Imperial quarts as well !.

      Holy smokes. Clearly not a deal on that truck. I just mean in general, matte or painted trim is becoming more normative than chrome, but I know the Black Optics packages on various vehicles are being sold as uplevel trims. They look really good, but sheesh. It's just paint and plastic.

      Some Assembly is Required

      I Wouldn't Know Where to Begin    Oh I know where I would begin but I'm just one of over eight billion people on this rock. Eight billion versions of where the goal post is. How large it should be. How far to kick from. What ball is the right ball. Elevation. Age.....are you getting the point? It isn't about disagreeing with one individual. It's about agreeing only with one individual. One's self.   Agreement comes when multiple people hold the same point already. THAT is the goal of an education. Building the Social Contract. That thing that allows us to all read this sentence. We've agreed on the alphabet and how to arrange those letters into words we agree upon whose meanings hold true for everyone entering into that contract. Those words arranged into a sentence form an idea and several sentences strung together in a paragraph convey an argument for or against or inform the reader of a state, condition or perhaps reveal a things nature. Paint a word picture. Make oneself known.    This contract is not limited to words although they are often explained by words. Things like numbers and their usefulness. Physics, Chemistry, Medicine, Music, Art and so on.    The frequency of middle C (C4) is 261.63 Hz is a first principle. We build on that to make music we all can enjoy even if we all can not compose or play. You don't have to master it to make it enjoyable and useful.    So why is the Beginning so difficult? Why is agreement so elusive?   Everyone "Signs" the contract (when receiving that education in obtaining it)  but fewer and fewer in this world have any intention of living by that contract. They find exploiting that contract more advantageous. Disruption. With intent. Without intent. In Ignorance. In your face. With a double dog dare you. With a hold my beer. In resistance to that contract and in spite how it looks on us. It permeates the very air we breath.    In this way the contract is subject to advantage. Abide by it when it serves you, disregard it when it doesn't. Unpredictable and self-serving. Corrosive.....Toxic........   It says a lot about a persons character to disregard the contract, the truth, first principles. None of it good.        ********************************************************   https://medicine.yale.edu/news-article/character-vs-personality-who-we-are-and-who-we-aspire-to-be/   Just an interesting article.
