Hello everyone. I've recently purchased a 2020 Silverado 1500 from a dealership. I found out late in the sale that the truck was used as the dealerships "loaner" which didn't really bother me even though I know people beat up those vehicles. Anyway, I'm pretty in-tune to vehicle sounds and I had a couple of questions regarding noises I'm hearing from my vehicle.
The first is a clunking noise and a physical jolt when I shift from Drive to Reverse. I have my foot on the brake and am on a flat surface. I notice it a lot after I've been driving for a while and go to back into my garage. I took the truck back to the dealership and they chalked it up to bad U-joints. They slapped 2 fresh sets on, but I've still go the issue. Any ideas what it may be? I don't feel like anything is going to fail, but I also don't like the sound and don't think it should be that way. I have another service appointment next week and I'd like to help them out with ideas considering they don't really seem to care.
The second is a ticking noise coming from the undercarriage. I' got under the truck today and believe it's coming from the rear portion of the engine, but I'm not for certain as I've never been beneath the truck while it's been on a rack. The noise cannot be heard when standing at the front with the hood up, but I can hear it very noticeably when standing at the driver's door. I do not hear it as the engine is heating up, but that could be because every other component under the hood is loud as h*ll while the truck is heating up. Once the engine is approaching operating temp, it's very noticeable. As you can hear from the short video, it's every .5 to 1 second or so and is always present during idling. Again, may not be a big issue, but I hate hearing things on my vehicles that I can't attribute to something else.
Thanks for reading my ramblings. I can try to post longer videos if anyone needs. Thanks in advance!

Hey Everybody. I’m about to have my 2014 Silverado AFM deleted with stage 3 cam upgrade, longtube headers, l86 intake, l86 TB, 3200 stall, custom tune. My question- is their other things I must do to go with these upgrades? Truck is 4x4 but will soon be lowered. Driveshaft? New Trans cooler? Bigger oil pump? Any help would be appreciated. Thanks in advance

I have a 2017 Chevy Silverado and I have been having trouble with the entire radio and screen .. I recently replace a bad HMI module that I got from infotainment.com and it solved the issue. Now the screen is back to black and the display where the gauges are says “audio off” any idea why ?? Anyone have this issue I tried everything. Maybe I need a new ACM module now? HELP !

How are my Brother and Sisters making it work? I’m struggling tonight. I’ve done a lot and overcome much. As I age the pain is overwhelming. 62 YO 90% disabled VA combat vet of USNavy and USArmy. Never asked for help and for 42 years have helped others. My truck, the science of automotive technology helps me maintain my sanity. Any others here that feel the drain on the soul and body? My fingers and formally strac functions don’t function right anymore. I love the constitutional basis of USA but wonder have many forgotten the rule of law? UCMJ? Caring about others before self?

Good Morning Yall,
Long time lurker, first time poster as a member, and really appreciate this forum.
Recently the past year I have had some symptoms that didn’t affect the drivability of my 2014 Silverado z71 4x4 5.3, but were very present on a random basis, especially during rain.
Service Stabilitrak, Service Trailer Brake(nothing being towed) popping up the screen, sometimes binging back to back for extended amounts of time near to 30 minutes frequently.
Today the truck would not start, and presented these codes above under a check engine light. The truck started after having the battery disconnected for 15 minutes and has started since so far the previous 12 hours. Also while driving and the typical service notifications, one headlight being out, the truck engages the transmission at a slow roll/acceleration and a very very rough/lurching, almost feels like being rear-ended engagement, it would not engage power steering, and also presented a warning of reduced engine power. Some of these symptoms of course seem to be directly related to the codes, but seem to have progressed as time has gone on.
One issue noticed was a tail light having a small crack, and a sliver of water pooled inside of it. I am unsure if that may be related to the issues present, but I have ordered new lamps.
I have also previously installed a new ground cable from the battery to the block, and also verified the ground on the driver-side front beneath the dash/tweeter. The battery also tested good, so did all of the fuses on the battery side and the box side with the voltmeter. I have not checked the starter or alternator, but they are less than a year old.
Any help or suggestions would be greatly appreciated.
