Pictures for the steering wheel.

I have an instrument cluster and steering wheel from a 2017 Silverado WT. Both were removed when I upgraded to the Denali cluster. The instrument cluster is the most basic cluster that was installed in these trucks, and the steering wheel is basic as well. The steering wheel has cruise control buttons, but no buttons for the Display Information Center or radio controls. I do not need them any more and was about to throw them in the trash. I'll keep them for a little longer just in case someone on here wants them. I'm letting the items go for free, you just have to pay shipping. The cluster worked when removed and has been stored in a box since then. Let me know if you want them!

Look at these: Search on "Denali cluster". There's a lot to read in there about this.

I had a 2017 Silverado WT and I installed the Denali cluster and replaced the steering wheel to add the additional controls. The original steering wheel was the base wheel, I replaced it with a leather wrapped wheel. I believe that I had to add some wires to make it work, but it has been a few years. If you search on my name, you should be able to find the post that I wrote detailing the installation. I bought a programmed cluster from WAMS. For what its worth, you can also upgrade the radio so that it communicates with the cluster. I'm pretty sure that WAMS can help you with that as well. I didn't go that route, I replaced my base level radio with an Alpine unit. Because I had an aftermarket radio, there were a couple things that didn't display on the cluster because that data comes from the radio. The compass heading, for instance.

Harbor Freight has an attractive alternative. It has adapters for a variety of cars. Includes a reservoir so you can pour a quart in there and let it drain while you open another one.

I just noticed that your truck is a 2021. I don't know if they have front bumper light mounts for the new style Chevy/GMC trucks. I now have a 2025 2500 and I've been looking for bumper mounted light bar mounts for it and they don't appear to have them yet.

This is the website for the kit that I purchased. The picture below is my truck. https://zroadz.com/i-23909934-2016-2018-chevrolet-silverado-1500-front-bumper-top-led-kit-with-1-30-inch-led-straight-double-row-light-bar-pn-z322082-kit.html

The Harness Dr. sells conversion harnesses for upgrading mirrors. I went from power adjust/heated mirrors to tow mirrors that were power adjust, heated, turn signal, and reverse lights. I could have also added power fold but I didn't want that. I installed the mirrors and installed the harness that I got from the Harness Dr. and everything worked.

I had a front bumper mounted light bar from ZRoadz on my 2017 Silverado. It was easy to install and worked great.

I took it into the dealer yesterday and they confirmed that this is "normal." I don't know why an OEM would put untreated/unpainted steel under a new truck but that is where we are. There are some good suggestions above and I will decide what to do about it in the near future.

Last picture, I promise.

Another picture...

I have a 2025 Silverado 2500 4WD that I purchased near the end of December. I got under the truck today and noted that the metal parts of the front axle are covered with surface rust. Shouldn't those portions of the axle be powder coated or painted to protect the steel? The truck had less than 20 miles on it when I bought it, and less than 2,000 miles now. The truck was bought in Ft. Paine, AL and I live in Huntsville, AL, so no driving up north. Does anyone else have this issue?

I was a mechanic in the 80's and 90's and I've seen instances where cats overheat and cause odors in the cab. I've never seen any events where the differential vented enough fumes to be detectable in the cab. I worked on 1/2 ton and 3/4 ton trucks with big tires and solid axles. I believe that it is more likely a cat issue causing the smell than the differential vent, which is why I posted my comment. If I am wrong then I am wrong. I was simply providing some information from my experience so that the person who posted the question could consider it.
