No catch can and you’re still using AFM V4 / V8?!
How is this possible it’s still going?!
The only ones I have found are the outer tie rod ends.
Correct. Those are the only grease zerks I have found on my 2018 Sierra 1500
Update: cleaning the wax off frame and negative cable didn’t solve the random service stabilitrack message. Still had a month of warranty left so took to dealer. They replaced negative battery cable due to high resistance. Hopefully that solves it.
I’ve run 32.8” BFGKO2 285/70/17 on my truck with front lifted 1.85” from stock. No issues.
I had my cluster pre programmed for hud. My slt has the heads up led brake assist so I think my windshield is compatible.
Even with this kit you still have to cut your dash and fabricate a new cluster cover and upper dash trim?
I’d like to have hud but don’t want to saw my dash [emoji22]

Here is the TSB with the voltage drop test, Dash grounds G218 check, and starter heat shield shorting out on starter solenoid positive cable.

Final update I hope. Over a week with no alarms coming in but I was confused they replaced the Brake fluid reservoir level switch and that seems to have fixed the issue. Not sure why I never got low alarm but I am not looking a gift horse in the mouth. New owner dealer service mgr replaced it under factory warranty too. So hopefully I have many more miles trouble free.
Is your issue still fixed? I have a 2018 and get service stabillitrack randomly and immediately after startup then disappears. No other messages. The G18 dash ground should not be an issue on my 2018. I did clean the negative battery cable frame ground on the passenger side frame rail near the front fender liner. Mine had a decent amount of wax blocking the connection. Haven't seen the message but its only been a week.
Sorry to hear about the mishap but unfortunately happens!
id suggest the following:
1. Dr colorchip
3. Repaint. It will be hard to match to rest of truck since it’s a dark color and several years old But it doesn’t have metallic flake in it so that’s a big plus on getting the new paint to match very close to the 2014 paint.
Don’t beat yourself up too much. We’ve all had similar moments.
Let us know how it turns out & Good Luck!
My truck is a 2018 so it shouldn’t need the dash ground fix. I’m not having power steering issue but occasional service stabilitrack message in the DIC immediately after startup then it quickly goes away. The passenger frame ground had a decent layer of wax between the cable and frame. I cleaned it up with a paper towel. Issue hasn’t returned yet...
My neg cable didn’t even register a DC mv reading. My pos cable was 5.53 with a jump to 11.65.
Got a low battery alert which also notified onstar? after doing this test. I got an diagnostic email lol. Battery voltage is 12.62 so maybe my battery is weak? Or my random service stabilatrack message is a different issue.
Get rid of the spacer and add bilstein 5100 which will level the truck and give you an extra 1” of travel in the front. I’m running 5100 with 1.8” lift in front and stock height In rear. I have a slight rake which I like since I tow and don’t want to be nose high. I believe you can raise front 2.25” with 5100.
I have been getting a service stabilitrack on the DIC randomly on startup. Disappears quickly before i can Dismiss. Happens randomly once or twice every few months, only during startup.

Also if any of you want to know how to test the cables I can post that too
A. A digital voltage meter
B. An assistant
C. 1 beer- it’s a 1 beer kind of test. Replacing the cables are 1.5-3 beer job depending on skill level.

Hope everyone had a good thanksgiving and a safe one.
I currently have a 2016 GMC Sierra 1500 SLT A/T 5.3 4x4 with 71,****** on it. A few "dealer"ships have caught my eye on some 2020s and I wanted to see what you guys have to say about them.
I still owe around $10G on my truck but have gotten some good trade offers on it around $31G.
Is it worth it to trade in right now or hold off until a new generation comes out?
Personally I’d wait. New interior in 2022 models. Most likely slightly refreshed front and rear clip as well.
Your truck will be worth a bit less the longer you wait but I’d say it’s well worth it since 2022 models will be released late spring / early summer 2021.
Used vehicle values are high during this pandemic which will be with us for awhile longer.
I have no clue about rims. All I know is I am done with 20's rims and want to go back to 18's has anybody bought rims from Costco? Looking for 250.00 per rim easy to clean don't understand all the Offset and other nonsense.
Thanks...shoot me some ideas!
I sold my factory 20”s on craigs and picked up a set of 18” AT4 wheels off of a 2020.
FYI any oem GM 6 lug wheel 2007 - 2021 off a full size suburban, Yukon, Tahoe, Silverado, Sierra, Escalade will fit your K2xx. Must be 17” or larger wheel to clear the front brake calipers. Factory spare is a 17”.
Don’t have to worry about offsets when using a factory wheel.
Colorado canyon wheels will not fit as they changed the bolt pattern.
Moving to Texas? Take the 3.0 out on the interstate and check out the acceleration 70-100.
The acceleration 0-30 in the 3.0 is about the same as 70-100. It just does not bog down.
Then do the same in the raptor. See how many more downshifts, noise, and effort the raptor takes to accelerate or maintain those speeds. Take note of the lack of acceleration unless it downshifts.
Also, I can get on it a lot more with the diesel and be way more low key to my girlfriend next to me without her telling me to slow down [emoji23]
What this guy said ^.
On a related note I’d have a hard time deciding between the 6.2 gas and 3.0 diesel. They are the same up charge.
I love my 6.2 but I don’t have a long commute so the premium gas tax doesn’t bother me. If I was putting on a lot of miles then I’d go diesel for mpg.
285/70/17 approx 32.8” BFG KO2
Bilstein 5100 raised front 1.85” from stock. 1 notch down from max lift on 5100
Very little rub at full lock on upper control arm. could go to a 34” with some fender liner rub or just tie it back.
Laundry detergent cap works great for me. A loose fit. I could cut it down so it fits tightly but it’s never moved around since closed fuel door keeps it in place.
Very nice setup.
