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

    5 years after installing poly body mount bushings (https://www.tahoeyukonforum.com/threads/body-mount-bushings.129520/ ) I finally got tired of the super rough ride and body noise (popping, etc). Bought a set of S&B body mounts and installed them this afternoon. Call it a placebo effect but the...

    Another unknown clunk thread

    That’s an interesting idea, more along the lines of my thought about the hub continuing to rotate just a hair. The hardware is present and was cleaned up about a month ago when I disassembled the front brakes to clean and re-lube the components. I had used the purple Permatex brake lube when I...

    Another unknown clunk thread

    I checked both manifold heat shields and there were no cracks and the bolts were tight. I had the exhaust replaced some years back due to a cat failure. I’ll check the heat shields on the new system just to confirm they are fine. And yes it’s very true that sound likes to travel. I had some...

    Another unknown clunk thread

    Been chasing a sound that has become an annoyance as of late on my 2005 tahoe. Sometimes it’s a light “tink” sometimes it’s a “clunk” but it always sounds like it’s coming from the driver’s front. Here’s a short video of it, I’ve got a 5+ minute video that I spent an hour looking at each...

    What brand for brakes!?

    I’m using the Akebono ProACT pads. OEM brand for a number of manufacturers.

    Dreaded front end clunk? Check your transmission mount!

    Long story short, I’ve been dealing with an occasional front end clunk on my Tahoe for MONTHS and it’s been getting on my last nerve (the wife complaining that I still haven’t taken it in to be looked at is my last nerve lol). One random POP while braking and nearly stopped, it seemed to...

    Testing Throttle Position Sensor (2005) - UPDATED (Injector?)

    update: Was sitting in the drive thru last night and was hearing this: I gave it some throttle and it cleared up and the idle went back to normal. This morning I went out and started the tahoe and let it idle while I was trying to get some other things in the back. By the time the engine...

    Michelin Defender Alternatives

    Yes, another tire thread. I know tires have been beaten to death on here but I am posting [yet] another one to get an update for 2025. Long story short, I have the Defender LTX M/S on my tahoe now and am down to 5/32" - 6/32" after only 30k miles. Maybe just a bad batch, but needless to say...

    What's left?

    I did say that there may be more. I haven't looked too much in NM personally so I couldn't vouch for them. I've had some friends that lived in the area over the years and they talked as if everyone out there beat up on them hitting the trails, etc. and accrued a lot of mileage driving between...

    What would you buy if you had to replace your GMT800/900 SUV and couldn't buy a GM product?...

    If money was no object and I could find a true mint vehicle: - 100 series Land Cruiser - 3rd gen (or 4th gen) 4Runner - second gen Sequoia (post face lift) I love my GMT800, but she'll be 20 this summer and I have limited / near zero interest in anything newer that GM or Ford made. They may...

    What's left?

    I live in eastern NC (ENC) and there are tons of tahoes and suburbans, and their GMC equivalents, in this area. You have to do some digging to avoid the "fake country boy" specials i.e. 380k miles on its third rebuilt transmission with a destroyed interior and a crappy lift and wheel lights as...

    EVAP System.... found an o-ring where is it from?

    I believe he referred to this connection, between the spring and the main fuel filler hose (disconnected in this screenshot). Fuel filler neck vent. This is the only good option I could think of when the question was originally asked, noted in my first comment.

    HVAC control unit rebuilder?

    It's almost 2 months later, but I got a rebuilt one (digital control) from "pro-rebuild" on Ebay back in October 2023: https://www.ebay.com/sch/i.html?_ssn=pro-rebuild&store_name=prorebuild&_oac=1&_trksid=p4429486.m3561.l161210 Installed it and had no issues for a couple weeks, then had the...

    Testing Throttle Position Sensor (2005) - UPDATED (Injector?)

    went and checked some live readings on my lunch break. I did notice that at the midway hashmark on the temp gauge (between 160 and 210) I was getting a loud tick / knock. This is not my video but it sounded just like this: It was raining and I didn’t have a screwdriver or my stethoscope to...

    Testing Throttle Position Sensor (2005) - UPDATED (Injector?)

    The fuel filter is integrated into the sending unit for my model year. I may go out in a bit and see if I can read live fuel data on my scanner and report back. I did go back and look at my most recent oil analysis and trace fuel amounts were detected in the oil. I had 0.8% (under the 2.0%...

    Testing Throttle Position Sensor (2005) - UPDATED (Injector?)

    fuel pressure test results: KOEO: 49-50 psi. Held steady for the 5ish minutes I had it on while I was doing other stuff in the garage Running at idle: 59-60 psi. No noticeable drop or rise in pressure when pressing on the accelerator pedal (both slow, steady pressure as well as “foot to the...

    EVAP System.... found an o-ring where is it from?

    I know this is much later than you would have wanted, but it looks like the size of the purge valve o ring, though you said you already looked there. I don't recall any red o rings that small in the EVAP system where the lines connect, though there may be one in the female end of the small line...

    Knock Sensors

    To piggyback this, when I replaced my intake manifold gaskets I also did the knock sensors and harness. I did OE for the knock sensors and harness but immediately got a CEL. Knock sensors tested fine but had an issue with the harness. Ended up going with a Dorman harness and surprisingly didn't...

    Testing Throttle Position Sensor (2005) - UPDATED (Injector?)

    2005 Tahoe, 5.3, gas, ~223k miles. I’ve noticed recently (who knows how long it’s been going on) that when leaving for my daily commute that when pulling out of my neighborhood (wheel turned) that when I press the accelerator there’s usually a latent period between me pressing and the engine /...

    Chasing Down Oil Leak – 2005 Tahoe 5.3L

    Probably not everyone else’s preference but I’ll start at the top of the engine and work down until I see oil or residue. You might get lucky and it be valve cover gaskets, it may be more of a PITA repair. Have you double checked the oil dipstick area? Where the tube meets the block. I usually...

    AC clutch 2006 Yukon XL- loud squeal

    Did this only start after the water pump replacement? If so, are the other pulleys clean / has there been any transfer of residual coolant from another pulley onto the new belt? There is also the idler pulley. One way to test the clutch is to remove the AC belt. Spin the pulley by hand and...

    Wheel Bearing Failed, last bolt holding it on..

    I can’t help with the bolt removal personally at this point, but have you considered taking the loss and replacing the whole knuckle assembly? It’ll require the removal of the ball joints, tie rod, and CV axle (if equipped) but would likely take less time and effort than what you’ve been...

    2005 Tahoe Radiator PN confirmation

    Just an update. I got 21650 delivered just now and while it is also 34” for the core length, it’s only 1.10” thick. My current radiator (which would be 21647, aside from the length discrepancy in the part description) is 1.37” thick.

    2005 Tahoe Radiator PN confirmation

    I learned that lesson a while back with a blend door actuator I needed for the rear HVAC. It felt like every number I kept pulling up was superseded by another GM #. It doesn't help that the vehicle is > 20 years old now and parts have been reused across generations but it is what it is. I'll...
