My truck in the mornings when I start to back out sounds like loose lug nuts in cap. But all are tight and on the studs. It does not do this after backing just a short ways. Any ideas?6d3d905a65979cb211d326b1c549787d.jpg

Possible you are hearing the ABS self test.

 

I used to hear it all the time on some of previous GM vehicle, not so much or at all with my 2016. Though I haven't been listening for it.

I get the same noise when turning to back into somewhere. I took my truck in and told them about this during an oil change. I even checked it before I pulled into the service department that morning. Well they changed the oil and rotated the tires then came and got me so I could test drive with their mechanic. It did not make the noise one single time. The advisor said it would be documented and I took off. I still hear it from time to time though.

wheel bearing dust cap is another thing to check.

 

Eh? These trucks have had sealed bearings for like 20 years.

I think he means the little metal cap that GM puts over the CV nut on the front wheels. That shouldn't be loose since they are super tight from the factory with how they fit in there.

 

I would play with the parking brake maybe and see if it helps any. Does it do it regardless if it was cold or warm out? How about if it is humid or it just rained the night before? Maybe you have a little surface rust on the rotor but it is making noise when you first start to move. There should be no way your brake dust shields are rusting and making it come into contact with the rotors at your age so I would rule that one out.

 

Something I would check is that all of your brake bolts are nice and tight and that the pads are able to move freely. I would also suggest trying to gently ride your brakes when you back up instead of letting go of the brake. See if it makes any difference when the brakes are applied a little or not.

Yes,  I mentioned it because it happened to a friend of mine. Couldn't figure out want the noise was turned out it was that cap.

I see you aren't in a northern salt state, but check your parking brake shoes.  We get tons of issues up here in NY with them, mostly on trucks where folks don't ever use the parking brake.

Weather has not been a factor that I know of as do not hear unless widows down. Only does after sitting all night never after driving and parking 4 or 5 hrs.

Just curious, (as I'm one that never used the parking brake in any of my automatic vehicles) what issue should I be concerned with by never using it?
Our is it a case of you useing it after not using it for a long time, and hanging up?

Cables will rust/stick in place, same with the brake mechanism inside the rear hub.  I also don't use the parking brake much, but I do periodically use it to stop the truck near my house, just to make sure they still work ok.

Parking brake isn't meant to physically slow the truck down. It is used for parking just like the name implies. Ever park on a hill and when you shift back to D you get the loud slam and its hard to move the shifter? That's cause you are resting on the parking pawl in the transmission because you didn't use the parking brake correctly. Proper use is get the truck where you want it, shift to N, apply parking brake and let off the foot brake. The parking brake will take the weight of the truck off the transmission, then shift to P. Anyways, good idea to use it on inclines whether they are large or small and it will insure that everything keeps moving.

I've had the same issue since almost new 9 months ago. It's a binding like sound when in reverse only. Kind of a popping noise. Does it most of the time but not all the time. Just shrugged my shoulders at it.

That is it and only in morning. Can only hear if windows are down.

      Post your UOA, (used oil analysis) here

      By Black02Silverado · Posted

      Here's the second UOA on my 22 Wrangler with the Ecodiesel. This has 5k miles on AMSOIL Signature Series DEO 5w-40. The first one was dealer installed oil, no clue what it was, the second is what AMSOIL recommended, European FS 5w-40, Most of the Ecodiesel world is showing great results using the European MS 5w-40, I figured I would see how the DEO works. This is using an Ecoguard oil filter. It's my understanding this engine likes to shed aluminum.  We will see. So far I don't think this is too bad.

      Disable DRL's

      By revmanii · Posted

      I'm surprised nobody seems to offer a solution like the start/stop device I put in my new truck. Remembers my setting when shutdown. And while it still starts up in start/stop, it stores/evaluates what mode it was in when shut down and will change it whithin a second or 2 of startup. It'd be nice to have something like that for the DRLs.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.

      Joke Thread

      An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?
