When I get up to highway speeds (+/- 60 mph) I get a slight rattling noise when my foot is on the accelerator. If I let off, it stops. It sounds like it is coming from under the hood on the driver's side. The noise is a high pitch, fast, vibration type rattle. To me, it sounds like something that is metal, small, and thin is loose and when their is vibration from the engine running at a certain speed it causes the mystery object to vibrate and produce a rattling sound. Sometimes it will do it when I accelerate fast and wind out the gears more causing higher rpms on the engine. Any ideas?

I don't know if this even applies to the HD's because I didn't look at mine before I posted this. I had a previous vehicle that had an annoying rattle only at freeway speeds and only intermittently. It turned out to be the plastic molding that was at the base of the outside of the windshield. It would vibrate from the wind at freeway speeds. I stuck a toothpick between it and the windshield and it stopped it from rattling.

 

I don't know if the HD's have this piece or not because I didn't go check and I can't see mine out my window right now, but the rattle was so annoying in my last vehicle and it was just by accident that I found it so I thought I would post it so maybe you could give it a shot.

 

Also I was convinced that the rattle was coming from under the hood too. Good luck.

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
