2017 - Creaking Sound - Front Left Side (drivers side) - FOUND IT!

2017 LT with a very annoying creaking sound coming from left front/driver's side.   As typical, I take it in for an oil change and request to have them check the creaking sound and I get the infamous ("unable to reproduce").   Of course they say that!!   

 

So, before I leave I make the service manager get into the truck, we slowly roll around the lot and he says, "yes!  I hear it... yes I do."  Ok well, maybe you should issue hearing aids to the techs! ????

 

I have to leave, so I leave and reschedule.  One week later I return and request the tech come to the truck with me before I let them take it behind the curtain.   30min later, the tech shows up with the service manager and is ready to go for his ride to hear the sound.  He jumps in the truck!   I say, "no no no... there's no ride needed."   

 

So he comes back around.  I open the back door and get out a small roll of carpet and had it to the tech.  I tell him, "here, hold this for a second."  Then I go to the back drop the tail gate and pull out a long 2x4.   Keep in mind we are under the big service turn in bay and by now people are looking!    I go back to the tech take the roll of carpet, put it up under the front fender, then take the 2x4 and slide it between the tire and the carpet roll... then I go to the end of the 2x4 and tell tech to get down and lay under the truck and tell me if you can hear the creaking sound.   I proceed to work the 2x4 up and down and the creak is VERY OBVIOUS and he can hear it.   Imagine that!!!   He very quickly determines that it's NOT anything to do with suspension (I agree), he says that it's a body mount and that the body will need to be lifted and the mount replaced and the area cleaned and lubed.   

 

I said, "yep... I do agree, so here are the keys... would you also like my creak reproduction tools??"  LOL!   

 

To date, they still have the truck, so I don't know for sure if it will be resolved, I'm pretty confident though because that IS where the sound was coming from.  I will keep you all posted here.

 

I know there are mysterious creaks and squeaks with the newer trucks, so I thought I would share my story!   I have learned that if you take your truck in for anything like this, figure out and be sure you have a way to clearly reproduce the sound!

Glad to hear you found the source but if it was my truck I would rather live with the creaking noise then let the dealership mechanics take the body off the frame.  So much stuff has to be disconnected and taken apart that I would not trust them to get it back together right.  You may end up with more annoying creaks than you started with.

I had the creak coming from the passenger side however it was the lower control arm on my truck..

 

They replaced it and it's been fine since.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.

      Looking for this part for my truck. They don't sell just that one piece and to get it you have to pay over $100 even used for the whole air tube. The piece the hose clamp snaps into that is held on by the screw and nut. If anyone has access to one please let me know.
