Upgrade package - exhaust/suspension/wheels
Thanks for the reminder to follow up, yeah family comfort / daily driver still the priority for this vehicle. For exhaust I went with the “Chevy performance” cat-back made by Borla for the 5.3, includes the anti-drone valve and I’m quite pleased with the sound. (It was never about performance...- Danneman

Upgrade package - exhaust/suspension/wheels
You got it, bud - thank you. For a toy car or my shifter kart, I don’t mind learning how to do things and inevitably messing up in the process - but my daily driver has a family job to do and it’s a zero fail mission, no time for me to work my way up the curve. The shop foreman at my dealer...- Danneman

Upgrade package - exhaust/suspension/wheels
Thanks everyone for their thoughts. If there is a non-zero chance that my vehicle already has some or all of the MRC wiring, does anyone know how I could confirm? What would I look for, where?- Danneman

Upgrade package - exhaust/suspension/wheels
I hope I put this in the right category, apologies if I did not. I'm looking to make a few changes to my 2018 Tahoe LT, but the kind of upgrades I prefer to stick to with for my daily driver are things that the factory could just as easily have made - like selected parts from the next trim...- Danneman

How to validate a windshield is OEM
Hey guys - been a while. New truck! Windshield getting replaced this afternoon, insurance agreed to cover an EOM replacement but I’m wondering what marks to look for on the new piece in order to confirm it’s OEM. Should there be a GM logo, or is there any particular code or anything I should... -

2018 Tahoe-EXPERIENCE changing axle ratio?
I do have the engine oil and trans coolers, I saw those on the build sheet. Fan and radiator, not sure - do we know the RPO codes for those options? My dealer just got back to me saying the speedometer would change and they have no way of recalibrating to the new ratio.- Danneman

2018 Tahoe-EXPERIENCE changing axle ratio?
My research is turning up a lot opinions on 3.08 vs 3.42, and that has been helpful, but I can’t seem to find a lot of folks who have actually had the change done. I have the 3.08 and per the manual my towing capacity goes from 6400 to 8400 if I had the 3.42. I have the 5.3 engine and...- Danneman

My 2018 tahoe front strut numbers - what gives...
Just above the 84082019, they show OE23837. I didn’t get any hits on that either. Kind of reassuring that my 84082019 didn’t show up in the list you provided? Maybe reassuring isn’t the right word. I feel validated that something seems to be off here.- Danneman

My 2018 tahoe front strut numbers - what gives...
First post in the 2015+ forum - been in the 1991-1999 group for a while. Happy to have made the upgrade to the 20th century. Purchased 2018 4WD Tahoe LT two months ago, 38K miles, was a fleet car. Front is bouncy. I'm looking for OEM part numbers on the struts and no amount of searching will...- Danneman

Update. Not a transmission issue. Rather, I'm getting misfires on cylinder 7 under load. I can see them being registered on my Tech 2 while experiencing the issue - normally the value shows "0" for each cylinder, but then as the misifre happens it shows the count and then when they stop it...- Danneman

When do we worry about brake fluid leaks - now or soon?
That's right, there's that unit back there in the cargo area! Ok, that has to be it...so no major operational issue that will prevent me from staying alive on the highways of Chicago, just a comfort thing. Thank you all!- Danneman

When do we worry about brake fluid leaks - now or soon?
A few drops of bright green fluid on the garage floor, passenger side, under the step rail. Took a peek and appears to be brake fluid. A little bit collected around a joint in the line. Not gushing, but obviously there's a leak. Just the one part of the one line, checked all others and did...- Danneman

Tech2 readings on engine data 1
Ok, so MAF cleaning did seem to result in some mild power increase but didn't resolve the main problem. And I was preparing a good response to all of the above, concerning my Tech2 readings and interpretations, etc., when I stumbled upon something in the service manual that seems to give me...- Danneman

Ok, so take a look at what I stumbled upon in the 1998 C/K service manual: apparently what I'm experiencing, GM calls a "chuggle" as per their shift condition descriptions. Found this on page 7-233 (in the volume 4). It doesn't seem to go on to talk about any testing procedures specific to a...- Danneman

Tech2 readings on engine data 1
Yes, I'm being careful not to pretend I know what I'm doing. There's data and there's proper interpretation of that data. Further searching on the CMP Retard suggests that the reading isn't any good until RPMs are over 1000, and that from there you rotate distributor (clockwise or counter...- Danneman

Tech2 readings on engine data 1
Ok, so I invested in a tech2 scanner, and thanks to this forum I have the service manual for the 1998 (mine is a 1999 yukon with 5.7). Took a look at my Engine Data 1 and compared this to what the Specs section shows as the "typical values." I tested under the recommended conditions: i.e...- Danneman

Ok - Thanks, I will make this part of my agenda at my next garage visit. Looks like it's part of the overall "Functional Test" outlined in the service manual so I'll just have the whole thing done. Meanwhile, I found a table in the service manual that outlines the typical values a scan tool...- Danneman
