    NNBS Brake Upgrade

    Did you bed in the brakes? What brand rotors and pads did you get? If you didn't bed the brakes, you won't get better performance, and it could be worse until they bed in.

    Billet Grille Noise - resonant whirring sound at 55+mph

    Looks good. Using half that width shouldn't block too much cooling air. I'd be careful using silicone as adhesive, make sure its rated as an adhesive, not a sealant and is rigid, not flexible. Epoxy might be a better choice, but as long as nothing flies off at 80 mph, all is good.

    Installing Sub and Amp into 2007 Tahoe Questions!

    Meh, it's a simple enough job and a good learning experience. Remember, experience is the best teacher. But it can also be the cruelest. Research basic stereo and car wiring, ask questions, and be sure you have a well thought out plan before starting. This will keep the magic smoke in the...

    NNBS Brake Upgrade

    Remember, you want just the FRONT brakes. The rear disks on NNBS are much thinner and only marginally larger diameter. Thinner means less heat tolerant. Not worth doing the rears, just the front. You will need 17" wheels for the NNBS fronts, but even if you forgot the spare and had a flat...

    Billet Grille Noise - resonant whirring sound at 55+mph

    You can change the resonant frequency of something by changing its mass, its stiffness, how it attaches to the world around it, or all three. Hard to tell by the far away pictures, but that kind of insert usually has vertical bars every few inches and the ends are free. Most materials...

    Billet Grille Noise - resonant whirring sound at 55+mph

    Yes, the grill can create a sonic resonator and whistle effect, but you can't solve that until you have it rigidly mounted. After that, either the bars themselves could vibrate or they could whistle. Adding silicone or rubber in the right place to change either the vibration frequency of the...

    Installing Sub and Amp into 2007 Tahoe Questions!

    You will have to run a power wire. That outlet doesn't have near the wire thickness running to it to safely power an amp.

    NNBS Brake Upgrade

    You can do just the calipers, pads, and rotors or you can swap the booster as well. I wouldn't unless its to swap to hydra-boost from vacuum booster. If you already have hydra-boost, don't bother. The hydra-boost helps with a linear pedal feel and reduced pedal effort, but not stopping...

    Billet Grille Noise - resonant whirring sound at 55+mph

    Resonant wind noise can be a real *****. Sounds like its an insert, so the first thing would be to make sure the ends are firmly attached to the grille surround. If it still gives you issues, you need to change the resonant frequency of the bars themselves. Pictures would be a help here.

    Flashing Check Engine Light during car wash??

    Plug wire insulation is probably cracked. They got wet, started arcing, caused the miss, and "burped" the TPS and MAF with high voltage. Engine heat dried them out, arcing stopped, sensors reset, and it runs fine again. Go out tonight with squirt bottle with some water. Start the truck...

    *Clunk* Noise From Rear End Going Over Speed Bump

    That "hardware" is the spring isolators. Basically rubber bushings which go between the spring and axle/frame to quite the ride and stop metal to metal contact. They are held in by the spring. There don't appear to be any spring retaining brackets, so everything is held by spring compression...

    Add-a-leaf squeak

    Don't use a hammer drill and concrete bit on hardened steel :badidea: The bit is shaped for stone, not metal and the hammer action will chip the bit, crack the steel, or both. Granted, your standard HSS drill bit won't get through spring steel, you will need to order a solid carbide or...

    *Clunk* Noise From Rear End Going Over Speed Bump

    Not positive, but that spring doesn't look seated correctly. It could be rubbing on the isolater and "climbing" up it and then popping back into place when you hit a bump.

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Installed a new HU with blue tooth. Made a phone call on it and tuned the EQ. I can finally hear bass guitar in rock tracks. But I think I'm going to try to get a new aftermarket 8" sub. I don't want louder or harder hitting bass, just tighter sounding. I might need new door speakers to get...

    Magna Flow Exhaust

    I do believe I detect the distinct smell of male bovine excrement.

    Calspeed headers....

    I'm too tired to use tact here, so I'm going to be blunt. What is the point of installing headers when you are just going to beat the primary tubes closed? You lose almost all tuning and scavenging on that bank, and closing off the tube increases back pressure, increasing cylinder temperature...

    If you give a mouse a cookie or choices, choices, choices.

    You're right, I'm no audiophile. I've significant hearing loss in various frequency ranges. I get more out of watching music on oscilloscope and looking at bode plots then actually listening sometimes. I ended up getting this...

    Checked today, and the stock sub works fine. The EQ however sucks.

    Keys + Bilsteins Front, 2" Spacers + Extenders on OEM Nivomats Rear

    Do you have any pictures of the truck without a trailer on it and the rear shock extenders/spacers? I have a welder and access to machine tools, so I might just fabricate rear spacers and extenders. This is what I want to do to my Tahoe. Nothing big, just making it more usable off-road.

    Battery seems to drain too quickly

    You can get a duralast gold with similar CCA, CA, and RC as a Optima Yellow Top for around $100 less. Same electrical performance, you just can't invert it or beat on it like a yellow top. But you don't need a bomb proof battery for a DD/tailgate rig. I like to get the batteries with both...

    Battery seems to drain too quickly

    Take the battery into the parts store, have them charge and test it. Make sure they test it for cranking amps, cold cranking amps, and reserve capacity. If it won't take a full charge or the CA, CCA, and RC won't meet the numbers printed on the battery, replace it. This test will take a...

    If you give a mouse a cookie or choices, choices, choices.

    I'm the new owner of a 2001 Storm Grey Tahoe LT w/ a Delco H/U 9 speaker system and remote tape deck. The system is completely stock and doesn't sound bad (though I am half deaf), but the lack of an auxiliary input is killing me. I thought about adding one of these...

    Towing and lowering

    The only way to lower a vehicle without affecting ride quality or load handling, you will need to move the spring mount points on the axle and frame to lower the vehicle while using the same springs as factory. Even then, you may need stiffer springs to account for the lessened travel to the...

    rear wiper stopped working 03 Tahoe

    I'm having a similar issue. Wiper will pop up but the motor makes a horrid grinding noise when you try to use it.

    The 4 Hi mod for a 2000

    So does anyone have a circuit diagram for the low beams, high beams, DRLs, and fogs? Are they all on relays and are all relays sinking (provide ground) like the low beams? I want to make a switched harness that when the switch is off, all the lights behave stock. Flip it on and activating the...
