I resolved this noise a couple months ago but my post did not get much attention. Here is how I made it go away forever.
For those who are still having this heat shield noise issue, I wanted to let you know that I have not had the noise for the last couple months so I believe it is now resolved on my vehicle.
As with many of us, this buzzing vibration noise has been eluding me for months. It sounds like a heat shield or thin metallic sound just as some of you have described. I typically only hear it randomly at very low speeds and rpm such as when I am turning into a parking space or reversing slowly. I'm certain it still happens at higher speeds but I don't really notice it because of wind/road noise or the music being turned up. I've seen the other posts mentioning the heat shield at the spare tire and leaf springs but this was not my case. I went back under the my 2020 S
The Hellwig rear sway bar is expensive but well worth it to me on my 2020 CarbonPro Denali (non-AT4). It was my best upgrade/mod and I immediately noticed the improvement in handling and lack of lean during corners and quick lane changes. I still have a stock front sway bar that works just fine in conjunction with the Hellwig rear. Hellwig makes are rear bar specifically for the AT4 with the higher suspension than mine. Here's my previous post on the install if you haven't come across it already. '
I have a Sierra 1500. I initially tried the popular aftermarket rubberized stubby you find on Amazon. It performed fine and required a thread adapter which was included. I only kept it on for a few months because it got tired of noticing it all the time. Although it was short, the thickness of it stood out to me. Just about all of my front seat passengers would ask, "Was that always there?", referring to the "covert-stealthy stubby antenna. I ended up replacing it with a shorter version of the factory antenna. It is 7 inches tall and does not require a thread adapter. Looks stock b
The sway bar is not required on any vehicles. It's up to your preference on how it feels and handles with your setup. Hellwig's website shows that they have a rear sway bar that will support lifts from 2"-4". REAR SWAY BAR KIT2019-2020 GM SILVERADO/SIERRA PICKUP W/ 2-4" LIFT Part Number: 7844 You may have to contact them to see if they have any additional hardware that supports the 6" lift.
I don't think a dealer will touch it because it is not an accessory provided by GM or dealerships. I installed it myself and I don't recall having to take anything apart during the install. You just mount the hardware to the vehicle in certain locations. So far I can't see any reason a sway bar could be detrimental to the ARC or would void your warranty. GM chose not to include a rear sway bar on their 1500 trucks (probably to save cost) but I notice that all of the recent Tahoes come with rear sway bars. I had a 2017 and a 2020 Tahoe with factory rear sway bars and both of them hand
Yes, the rear sway bar prevents a lot of that front end dip and body roll around the ramps and it makes it seem like all four tires are planted more equally. I only added the rear Hellwig and there's a factory bar already on the front. Traction still feels balanced, no noticeable oversteer or understeer around a quick corner under acceleration.
If you are satisfied with your existing amount of sway, you may not want an aftermarket sway bar. Your driving style may not require it either. My truck has the ARC and Max Tow Package. My ride comfort didn’t change and it doesn’t seem to compromise the ARC system at all. I feel the rear sway bar made an improvement that was most noticeable for the investment. It added more confidence in cornering and evasive maneuvers if necessary. On and off ramps are easier at normal speeds because there is less leaning going on. If you do decide to go with a sway bar, take note that the
Although this sway bar was a litter pricier than most, it was the best upgrade I have done so far and well worth the money. You will notice the improvement immediately and enjoy driving your truck even more. I recall being a little disappointed with the amount body roll it had when I first bought my truck but now it corners so much better. Enjoy your upgrade.
I think I experienced the same issues you had but just didn't mention it. Sorry about that. I had the leftover black washers too. Glad you got it all figured out and are enjoying the cornering with confidence. Great job!
As you can see from the image, I installed mine using the 3rd hole from each end of the bar. This is the stiffest setting and there are no drawbacks or regrets. The ride and suspension seem just fine. I have inspected everything a few times since the install and have not had to re-tighten anything. Feel free to ask if you have any questions on it. Good luck with you install.
The dash speaker plug is different from the door speaker plugs so they won’t work. Don’t cut off your dash speaker plugs. Just tap into each wire and extend it to your replacement speakers. I did this a few days ago. Use wire strippers to score the wire insulation behind the factory plug and pulled the insulation to each side to expose the copper wiring. Be careful not to damage any copper strands. Wrap your new wiring around the exposed copper and solder it. Seal it up and you’re done. The factory plugs will still be there in case you ever need them again.
