    HEADERS, MANIFOLDS & CATS

    As I build the courage to do my own cat replacements, I think of the biggest issues people have regarding those manifold bolts breaking/stripping where it connects to y-pipe. I wonder, wouldnt it be easier to buy new/upgraded manifolds and remove from there instead of the y-pipe. Also, what is...

    This site has blessed me with the knowledge to change all the fluids in my truck when i first got it. I wanted to see if the recommended fluids changed along with how much. I tried searching but I only seem to find discussions of issues/replacements rather than maintenance so far. I believe I...

    A/C Fan On/Off & Cold in the Front, Hot in the Back

    I'm dealing with 2 issues. The front motor/fans turn on and off. I know its related to the blower or actuator under passenger seat. When I play with the wires, it goes on and off. It seems to matter most on the side of the blower more than the actuator. Also seems to get really hot when A/C...

    Covid Cleaning Interior

    As alcohol becomes more extinct locally, i'm wondering what can be used to clean the leather interior without discoloring or damaging. I have some rips so I'm not too sensitive anymore but i'm sure a white spot will stand out in black. I have the following but not sure what works in a spray...

    Grinding/Clicking noise during hard acceleration or hard cornering

    I'm sure its either my shocks or axle. Any suggestions on how to test to differentiate which? It seems to come from only driver front or both front sides. Truck too big and i think these shocks too advanced to do the bounce test.

    Aftermarket Install Options - Video Play

    I currently own an NNBS which was EXTREMELY limited in audio functionality when it came to playing videos through USB. Ended up upgrading HU to allow full functionality. As I think of the next truck to go for, I like the new Tahoes/Yukons of this generation but worry the same applies. Through...

    8" WOOFERS in doors?

    I am curious how hard it would be to install 8" speakers in the front doors. I had this setup on an older Nissan Maxima and it required some cutting but the Tahoe is a bigger door and that OEM speaker bracket takes up some space. Anyone ever install an 8" in stock location without any custom work?

    Bulbs - Inside & Out (No Headlight Discussion)

    So my license plate lights went out and I like to wait for these times to do upgrades, when things go bad. In the process, I realized there hasnt been much discussion of other bulbs besides headlights. Can anyone share their feedback on bulbs they used successfully and possibly images. This...

    Adding Transmission 6L90 to NNBS (6l80)

    Just curious what would be needed to add the beefier 6L90 to the NNBS. Seems like a better replacement than the 6L80. I think it would be good to start with 6l80 first. The 6l40 might be a different animal to swap but hopefully its not that different.

    NEXT GEN Upgrade Parts 2014+ - what can we use?

    As newer generations come out, we sometimes have the opportunity to use parts they improved on to make our trucks better. Can we make a list of what can be interchanged? I'm not looking for anything that requires super custom work (unless worth it). Currently, I only know RIMS/TIRES can be...

    Feels like I got hit in the REAR when I brake

    When I brake hard, I feel a slight delay reaction where it feels like I got hit in the back or like the rest of my car just caught up or something. I'll check the motor mounts again but it feels like its coming from rear. Any suggestions on what to look for?

    D-Pillar speaker revisit - purpose and connections

    The speakers in the far back of the truck are the ones I'm referring to. Their position seems to be more of a "filler" position rather than a dedicated high or low like a tweeter or subwoofer. My audio expert friend confirmed they were a filler and not associated or connected with the rear...
