2020 Silverado 2WD sway

Hello all! 
 

Newcomer here to the forum and the GM family. Recently picked up a 2020 Silverado RSt, after 1,000 miles I decided to throw on some of the trail boss wheels and tires. They’re almost the same size as the stocks coming in at 275/65r18. 

 

First thing that happened was one of the rear lug nuts was stripped. So I decided I’ll just install them minus the broken one and take it to the dealer.I loosened every other bolt the same and none of the other ones stripped so I’m assuming it was just over torqued? Now right after changing the tires the truck feels like it sways/wanders from the rear. If i do a hard turn it feels as almost the back end is fishtailing. No vibrating or chatter, I’ve taken the truck up to 80.

 

I just highly doubt a single stripped lug nut can be causing the issue. I checked all kinds of tire pressures and the sway was still there. 
 

Any help would be appreciated!

You've torqued all the lug nuts properly on both sides, and then again after a day or two of driving around?  They can come loose fairly quickly, I've had the nuts come loose the next day on my truck after torquing them down initially (it's easy to see after ditching the hubcaps and switching to putting the plastic arrows on the lug nuts).

Well if you swap the rims/tires back to your stock ones and the problem goes away, then you will find the problem is with the tires.

That’s my next step, I’m just baffled as to why they started doing it on my truck when they were completely fine on the truck they came off.

The duratracs are a pretty mushy tire to begin with, I bet you that’s the issue. They drive like a winter tire in the summer, just don’t  wear like one

      Oil Consumption

      By KARNUT · Posted

      No I didn’t watch a video of a person who analyzes oil for a living explain general oil usage. For clarity I did ask my brothers one who runs our equipment business. The other who runs our old ROW business about oil usage. Nothing has changed since I retired. Their personal vehicles or work vehicles use no oil. Not enough to see on the oil checking device. Then I pondered. I like to ponder. In this extended oil changing world with oil change countdowns or lights. If engines used say a qt every 2500 miles or up to even 4000 miles. With oil changes reaching as high as 15000 miles. Normal for most people is eight to ten. Vehicles should potentially be seizing up all over the place. Especially in hilly terrain. Just how many people actually check their oil? Maybe 10 percent. Those are the people that probably change their oil early. I like to research used car listings. I have five favorite dealers I check. They all list carfax with their listing. It’s rare to see vehicles with anything but extended oil changes. Transmission service, forget about it. I’ve seen Honda and Toyota certified vehicles up to 100K miles and ten years old. With nothing but normal maintenance. Isn’t nice we all have different experiences and believe our way is the best. You certainly get backup for whatever you believe. Life would be boring otherwise.

      RUMOR / INSIDER: 2027 Silverado Dealer Reveal NEXT WEEK

      By RobbertClaus · Posted

      Interesting rumor. Dealers near me have been tight-lipped so far, but if this reveal actually happens next week, I'm really hoping they finally give the HD a proper interior overhaul. The competition has been eating their lunch in the cabin department for a while now.

      Oil Consumption

      By Chuck FB · Posted

      There are a few good takeaways in that video that pertain to this thread, certainly the possibility of the oil control rings having buildup, the fuel injectors and how clean or not that they are ending up affecting the pistons rings carbon buildup, and the fact that its normal up to a point for a given engine to use some oil, and that the oil quality that is being utilized is part of that ring clogging up issue as well.   I was talking with a neighbor yesterday who has a baby LZ0 duramax and he had bought it slightly used but it does consume some oil and he has switched over to 5W-30 Euro spec oil and in this case that never made a difference in consumption over the factory 0W-20 recommendation. He finds it uses a quart in about 3500 miles and as he goes a ways over that distance he adds oil to full and goes another 1000 miles or so and then changes oil and is typically at 40% or so left on the oil monitor at that point with his use case of quite a lot of highway miles and more limited in short run use. I don't know what other LZ0 engines are doing for oil consumption but that is what his is doing.

      Ok well I guess Lake disagrees with me on a few points. I call oil consumption pretty basic. Rudimentary. He calls it "really complicated." I think 1qt consumed in 3k miles is a lot. He says that's normal. In 22 minutes, he'll use his natural talent to explain oil consumption to anyone watching this video. He covers everything from obvious engine damage to how normally functioning healthy engines consume oil by design. Lake explicitly states how you drive will impact oil consumption.   Shut up and watch:
