The downshift may have been fixed with a software update or relearn. Depending on the year, I see the early calibrations with much faster downshift times than mine. I moved mine closer, but it is still 0.100-0.200 seconds slower in spots.

 

I checked the torque on mine. The driver strut was not to spec and some of the LCA bolts were slightly under. I have issues replicating, but I guess that is good. I only notice it on sharp turns when I drive into it hard. It just bothers me it happened 2x this week.

I took mine in today for the popping and harsh downshift.

 

I was told that they retourqued everything but still had the popping so they are going to replace the leaf springs eventhough I told them it was heard near the front.

 

They told me that the leaf springs could transfer through to the front, I call BS.

 

I ask what did they do for the hard shifting and he said the leaf springs are causing that too, I call BS.

 

Either way they are replacing the leaf springs once they come in. Ill be honest I haven't had a hard down shift after I took it in.

Did replacing the springs help with the popping? Been too 3 different mechanics. My spring make a lot of noise but I didn’t think I would be able too feel it up in my feet.

Looking for a solution to this problem too. I get front end popping at slow speeds with sharper turns too, especially off-camber loading one side more than another.

After having the same popping noise on my recently purchased 2014 GMC Sierra 1500 SLE I took it into the dealership who told me it was the struts due to a 3" leveling kit that was put on it. They recommended a bunch of repairs totaling over $3800. Not feeling satisfied in the answer I took it to another mechanic who told me I needed new tie rods/ball joints to get rid of the problem and it would cost $1700. Still not being satisfied I took it to yet another mechanic who told me It wasn't any of that. It was the Rack and Pinion that needed to be replaced and it would cost $2200 + an alignment. I didn't like any of those answers so I began researching myself and found this issue was the Rack and Pinion Dampner rings. The fix costed $40.

Moral of the story... Mechanics suck now days and are only looking to make a quick buck. You have to do it yourself.

I had the popping noise at low speed/sharp turns and side to side weight shifting (pulling out of my flat driveway goes to a slightly uphill road) I ended up loosening and re torquing the LCA’s to the above 129ft/lb. Popping gone for me. I noticed my drivers side front bolt was significantly more loose compared to the rest. 
 

2.5” level with Bilstien 5100’s and had 35’s on there until last week. 
 

Took ~30min with driving up on ramps, gathering tools, and drinking a beer.

Had this issue pop up last week. It was a bad sway bar link. Went ahead and replaced both sides. Took about and hour and 30 of that was rounding up tools and such.

I have a 2015 GMC Sierra all-terrain 4x4 with a 4-in level. I've had that same popping or grinding sound and assumed it was the steering rack, but it is the crossmember that's loose. I have tightened the crossmember to torque specifications four times. It lasts for about 4 days and then as loose again. Do I need to get different bolts for this thing or should I just weld the crossmember in place?

My 2016 Silverado 1500 LT Z71 5.3L does the same exact thing. My first time actually googled it and right from the very first result on down I seen many people are having the same issue. iOS am not a certified tech but much of what I have been reading is in agreement with the knowledge and experience I do have assuming you’re hearing the same noise from the same location appears it could most likely be in ascending order the CV joint, ball joint, strut, brake caliper, motor mount. If it were a wheel bearing other symptoms and noises would be present and precede the clunk.

    • I have a 2015 Silverado and sometimes I can not get in to the truck. I use the key to unlock the driver door. Something is locking the truck when I unlock it, last night I left the truck open and this morning it was locked with the mirrors folded in. This happens while driving so it is now a safety issue. I reach down for the folding button and they open, then they close again.  Any advice, thank you,   Ed
    • Did you ever find a resolution to this? my 2019 Silverado 1500 is showing the exact same headlights issues with the exact same symptoms.  would help a ton if anyone has any advice on this or better yet a known solution..
    • Wawa and Meijer here have ethanol free (88 & 89) I use for my mower and lawn equipment.  Its not much more than reg.  I paid $3.29 a few weeks ago.  
    • tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.
    • NewDude, thank you for the suggestions!    I did follow up and the dealer indicates he has an open CX case and is working with DPAC (Dealer Parts Assistance Center).   Per the dealer, GM has had a quality spill and is not providing an update for when a replacement engine will be available.
