    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    This is the first I've heard of an airbag recall for our vehicles. How does one check if it's been done?

    Autoride bypass

    The specifications are the details. Search on "25 watt 3.9 ohm resistor" and look for a finned body with mounting tabs.

    Took The Oil Pan Off Again

    Am I reading the TSB correctly that engines built after October 2010 already have the AFM valve shield in place?

    Fishing camera wire?

    I pulled the roof center console and the upper right windshield trim down, and removed the over-the-door trim (front and rear), B-, C-, and D-pillar trim, and the rear door's inside top trim piece. I ran the wire outboard of the airbags, through the rubber body-to-door conduit, drilled a 3/8"...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Having the same experience working inside doors and the inside of fuel tanks, I finally got a "cut protection sleeve." This is the one I have, but there's a wide selection of others.

    It's not "just" butyl, and in fact butyl makes up less than a third of it. A substantial portion is filler to make it more substantial (i.e. give it "body"), so it's not interchangeable with the variety you'd use for glass. See the MSDS excerpt I've attached.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    If you need to fix something quickly and already have it on hand, silicone is serviceable, but something that's good to have around is 3M Strip Calk (yes, that's the correct spelling). Imagine if a Tootsie Roll and a glob of grease had a baby, that's what Strip Calk is. It can be quite messy...

    How do you power your dash cam?

    I ran two 18-AWG TXL power wires (one constant, one retained accessory power) from the under-dash block above and to the left of the brake pedal, up the A-pillar, and across to the upper console.

    Is there something wrong with the suspension on this 07 Yukon?

    That jumped out to me immediately upon seeing that pic.

    Phone Mount Location?

    I am going to do a full(er) writeup in its own thread when I'm done with my setup, but for now here it is. I fabricated a couple of brackets using my hobby-size CNC machine to hold my phone and tablet. In short, these mount through clearance holes in the trim piece and are fastened to the...

    Dang, that is indeed quite different! Thank you for all the pics of the setup & components.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Can this arrangement be retrofitted to our GMT900s? I've already got a brand-new OE spare on hand, but it'd be good to know if this would be an option.

    Is There Any Data on The Weight of OE GM Full-Size Truck/SUV Wheels Out There?

    Y'all, My Tahoe with the 20" Style 5416 wheels is probably going to need new tires within a year, and I'd like to change over to lighter OE GM wheels, assuming there are some that are notably lighter. The only wheel I've ever seen discussed here as being "lighter" are the 18" Style 5355/5356...

    Any Advice/Experience with Cleaning A Jittery Volume Knob Encoder?

    Thanks, I'm sufficiently skilled in such endeavors!

    NIB 2002 Sierra 2500HD 'Winterfront' front end cover - $100

    It is, but the distinction between this and a regular protective bra is that it has adjustable grill airflow-blocking sections, hence the "winter" part of the name.

    Highway driving - do you make constant corrections or can you relax?

    ... or hunts back-and-forth in ruts in the pavement, even if they're so mild they can't legitimately be called "ruts" and are imperceptible to the eye. Case in point, my '86 BMW 535i when I was stationed at Fairchild AFB near Spokane, WA and would be traveling on the concrete portions of I-90...

    Highway driving - do you make constant corrections or can you relax?

    An underdrive pulley is what I suggested against doing. You'd want to use the pump modification I linked to, if it can be applied to our pumps. Past that, there are "hot rod" type in-hose bypasses, but that involves modifying the hoses themselves (i.e. cutting and crimping on at least the...

    Highway driving - do you make constant corrections or can you relax?

    The problem is how you get to the "2x less-assisted." If you reduce what the steering box/rack is getting via the valve, the pump volume is not affected, but if you reduce the pump output by reducing pump speed, volume is affected. Why does this matter? If you reduce pump output volume, you...

    Highway driving - do you make constant corrections or can you relax?

    Increasing pulley size is possible, but there's the risk of lowering the output enough at idle that low-speed steering could be negatively affected. The preferable way would be to use a kit like this, which I've done on other GM pumps. It's not clear if this will work on our GMT900s, though.

    Highway driving - do you make constant corrections or can you relax?

    My '13 LTZ 2WD with ~195K, on 80% worn stock-size Defender LTX M/Ss, and all-original suspension (AFAIK) does not have the issues you're describing. I wish it had more caster, though, as the return-to-center force is much less than my preference (I always increase it on my vehicles).

    Sensitive steering on highway

    I'd check the condition of the rear suspension bushings. A static alignment wouldn't necessarily catch wear that allows movement under dynamic conditions.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    The spring harmonics and the weights of the springs, retainers, pushrods, and valves would only matter to the tune if you're increasing the rev limiter RPM, and the valves would only affect tuning if their edge profile and/or stem size changed the flow more than a few percent.

    Assuming they're not knockoffs, they're available on Amazon.

    Looks like a case for prophylactic use of a metal cable tie for backup!

    To Change or Not Change my Transmission Fluid & Filter

    This is a really common error, but it's Dexron -- no "t" in the name.
