We traded my wife's 14 in on a 17 about a month ago. On the 14 I had the flapper valve removed after we had owned a while and within a week of picking up her 17 I drove it one day and had the valve re

Another exhaust system on order at the dealer. 3 exhaust systems in the first 18,000 miles. Unbelievable.

Mine was squeaking also at 12k miles. I could only hear it with the window down or the backwindow open. I used a 1.5" drywall screw through the open corners of the squares with the valve open. 

 

It has a teeny bit more sound at startup, no other difference.

Yes. There is a TSB for it. You will get a new exhaust system, then cross your fingers it doesn't make noise

Any idea what the TSB # is or what to search for exactly?

I’ve been looking everywhere for the TSB# and can’t can’t seem to find it. My 2017 5.3l has been squeaking since I bought it new with 24 miles on it. The dealer said they would replace my exhaust it if I had the service bulletin number. I’ve got 32k on it now.

I sprayed my flapper on my 2015 Sierra with FLUID FILM and after the first application it was half gone and after the second spray no more squeak!!!!

Had this squeak for a couple years and it was driving me crazy, didn't know where it came from. 

The FLUID FILM hasn't burnt off either as i drive 120 KMs to work and back on the highway and it still is quiet and no more SQUEAK!!!

      Some Assembly is Required

      By Grumpy Bear · Posted

      Disassembly may be Required!   Every blender makes claims but do  you ponder those claims? What was really said? Was it true?  Motive for saying it? What does in infer?  Is that inference true?    Let's do one.    Claim: Made from shear stable base oils.    What was said: Base Oils are shear proof.   Was it true: Yes.  ALL base oils are Newtonian.    Motive / Inference: To imply the fully formulated product is Shear Proof.    Is the Inference true?: Most fully formulated multigrade oils contain Viscosity Modifiers or VM's, sometimes called VII or Viscosity Index Improvers. There are four types. One is in fact shear proof but it also has a bad effect on extreme cold flow and is restricted to use in specialty oils. A second has limited shear called a 0-5 SSI polymer. Meaning its shear is limited to a range of zero to five percent as reported by the ASTM D6278 Shear Stability Index test. A few high end oils, like Torco SR-5, use them and brag about it profusely. Actually all that use it point it out. The last two shear dramatically and are often marketed as a 'feature' of the product aiding the oil to meet fuel standard requirements of ever stricter rules. One shears more than 5% and the other up to 20%. As you make guess, cost is directly linked to shear down and as such the majority of oils use the cheapest organic polymers sold to make grade and pass stringent tests.    PPD's or Pour Point Depressants also shear a bit, only a few percent and hide inside the 0-5 SSI capabilities.    The blender knows he can not out engineer Stribeck. Physics is not a suggestion. But he can wordcraft the unsuspecting toward believing a false claims INFERENCE. This is LEGAL. It is COMMON, and it is EFFECTIVE.

      I don't recall ever dealing with one on an '06 and back. It may not even exist on that. I can't remember for sure.   Any kind of ice in or after the evaporator is normally due to low charge with both a clutch-cycling orifice tube system, and a TXV system.

      HighMileage oils or stay with Dexos 1 ?

      Engines wear. It is unavoidable. So the question isn't if it will wear out but rather WHEN it will wear out. That question is about rate and RATE is a HUGE problem for almost everyone; but not in the way we may think.    Unless there is something drastically wrong with your powertrain, wear is exceedingly slow. It doesn't wear out in minutes or hours or days or months but in years or even decades. Ditto sludge and varnish. Humans are an impatient lot so to see the benefit of a truly superior product you may have to wait a very long time. Most will get bored first and trade before they reap the benefit.   Humans are not companionate creatures when it comes to those we do not know. We don't care what happens to the second or third owner as long as it doesn't happen to us or someone we know and actually like.   Sad commentary on humans but it is what it is. That thus, then, there is no advantage...to or for you if the above paragraphs adequately describe you.    BUT if you are a buy and hold type and patient enough to reap the rewards of your labors then that thing that is happening that you haven't yet seen, but will; can be abated by such products. Seals harden and leak with time and lots of it. Rings stick after thousands of miles of a slowly building plaque of varnish.    Then there is this. This didn't happen over night and this poor fellow knew when he removed the cover and not one second before.   Not "aware' isn't the same thing as "isn't happening".        The above was typical of the Ford 361 and 391 bus motors on Bulk Pennzoil Mineral Oil products on 3K mile OCI's at about 60K miles back in the 60's and 70's at the Anamosa School District when my Uncle took over their maintenance program.    This is Pepper at @ 165K on 5K OCI's using Group IV/V Full Synthetics.      HM oils will help the first but not the second.    Then again if one used..... ah, ya know.....

      Awesome you got it sorted! That's a new potential issue I'll have to mark in my book of issues. Thanks for the feedback.
