    Squeaky pass side front suspension - SOLVED

    2013 Tahoe LT 4x4. As title says I'm getting an annoying front suspension squeak going over bumps at low speed and, to a lesser extent when steering at low speed. All front suspension components are no more than 1.5 years old/10k miles: struts, sway bar d-bushings and end links, tie rods...

    Build thread - LMG 5.3 to L96 6.0 swap

    Say hello to my new engine - L96 6.0 from a 2014 2500 Silverado. Bought it from B&R Auto Wrecking, Portland, OR yard. The truck had 197k on it, but engine has a 6 month warranty and compression values 190-200 psi in all cylinders. Plus I'm wondering if it's a crate replacement, see later in...

    GMT900 Engine removal options

    I recently saw a thread like this, but it was for 2015-2020 so I'm starting my own. Starting to plan engine removal for 6.0 swap on my 2013 4wd Tahoe LT. What's the preferred method for 900s - up and over core support, or remove core support and pull it forward? I was always thinking up and...

    Considering bare long block 6.0 LY6 for swap

    I just saw this LY6 for sale on FB marketplace. Is this a good candidate to swap out my 5.3 LMG in my 2013 Tahoe? I’d like to keep flex fuel capabilities, but it’s not a requirement - I never see e85 in my area. Would I have to use a l96 cam to do that, or are l96 and LY6 the same? Is...

    To level on not to level?

    I’m torn on whether or not to install a 2” Rough Country leveling kit on the front of my 2013 LT 4wd. I’m upgrading to 18” stock wheels from a 2016 era truck (from 17”) and going with 275/65/18 (essentially 32”) from 265/70/17 (essentially 31”). I don’t expect rubbing to be an issue with the...

    Occasional front end pops/clunks - CV Axle?

    2013 Tahoe, LT, 4wd. I'm getting occasional front-end pops or light clunks during low speed turns. Both left and right - I can hear it at the respective wheels. More likely to happen if it's a full lock turn, like getting in or out of a tight parking space. I recently replaced inner and...

    Considering L96 6.0 Swap - Initial questions

    I'm in the very preliminary stage of planning an LMG 5.3 to L96 6.0 swap for my '13 Tahoe. I'm hoping to move on this sometime this coming winter or spring, but it could be a year from then, too. Rig has 210k with AFM tuned out. Runs good now, but I think I'm starting to hear a little lifter...

    Squeaks, rattles and vibrations - SOLVED!

    Thought I'd share in the hopes that this post may help preserve other owners' sanity. I've had my 2013 Tahoe LT (Leather, bucket front seats/console, etc) for a little less than 2 years now. Off and on during that time I've been annoyed by a lot of rattles and just a generally noisy, creaky...

    New Travel Trailer

    Picked up this 2006 19' Northwood Nash a couple weeks ago. Maiden voyage for us this coming weekend. A few projects for me in the coming months, but it's in pretty good shape. Microwave appears to not be working, so may need to replace that. Anxious to see how the Tahoe (2013 LT, 5.3) does...

    Speedo (suddenly) reading high

    This is a weird one, my speedo is suddenly reading high. Or at a minimum, I suddenly noticed it. About 14% or so. It'll be reading 50, but according to phone GPS (I have a speedometer app) I'm actually going 44. Similar percentage change across the range. I did a gear ratio swap last...

    hum or howl in 4wd

    Vehicle: 2013 Tahoe LT. 207k. I'm getting a hum or slight howl in both auto 4wd and 4-hi. Noise goes away (at least most) when letting off gas to coast or brake. Most pronounced when accelerating. noise stops immediately after switching to 2wd. I've only heard it in the driver's seat so...

    Melted mega fuse holder near positive battery post

    On a long road trip, taking daughter to college. Within a few miles of final destination tonight, smell burning rubber. Turns out the load side bolt on the mega fuse holder was loose, thereby causing arcing at that connection and generating a lot of heat. It melted the red cover, but more...

    Oil pressure drop after addition of OEM Oil Cooler?

    I just finished a build of many replacements and upgrades - documented here. One of the upgrades was the addition of an OEM-style engine oil cooler. I.e. I removed the block off plate, added a set of Dorman replacement lines, and replaced the radiator with a new Denso OEM-style that had the...

    Build thread - 3.08 to 3.42 front and rear gear change

    Starting a thread for my gear change. This week I purchased a GU6 14-bolt, Gov-lock rear end from LKQ. Came from an '09 Yukon. I've taken the cover off and removed the axles so far. Everything looks pretty good. No silver in the oil (although it was pretty black) and the parking brake...

    On road trip - getting P219A code

    On the front end of a 1500 mile road trip - going to pick up my daughter from college for the summer. (from Vancouver, WA to San Jose, CA, various side trips included) A couple hundred miles into the trip, MIL came on. Stopped at O'Reilly and got a scan (I don't have my Tech 2 with me)...

    Remote Start Troubleshooting - SOLVED

    Hello all, My remote start is not working. I've gone through the usual and obvious items that one can find on generic and GM sites. I have two remotes, both work normally except neither does remote start. No CEL. I've done diagnostics with my Tech 2 and I have just three codes: 1) radio...

    Need opinions: 3.42 vs 3.73 GR

    I know I want to change out the 3.08s in my '13, 5.3, 4wd Tahoe, just not sure if I want 3.42 or 3.73. Some factors I'm considering: - I don't tow anything heavy yet, but my wife and I are considering a small travel trailer. Upper weight limit would be about 5K. - Would like to stay with...

    Ready to pull trigger on Derale trans cooler - need advice

    I'm a little overwhelmed with all the different Derale options. And their website is not super helpful to gain understanding of nuances between model numbers. I've seen many instances of users here, including @Geotrash, using the 13960 kit. Amazon gives me a Does Not Fit warning with that...

    Front suspension rebuild - a couple questions

    I'm doing all four front control arms, new struts, and sway bar links/bushings. Done with driver's side, passenger side to go. For the control arms, I'm using Delphi for all four. Looks like the same castings as my original, just about every ridge and casting mark identical. Quality seems...

    Tech 2 showing multiple DTCs - Related?

    2013 Tahoe LT, 5.3. 198K miles. I've posted previously about a DIC message I repeatedly get on "Service Parking Assist." The system consistently works fine - all four sensors are triggering when appropriate, but the messages are annoying and I'm still wondering if there are underlying...

    SOLVED: Troubleshooting 2013 rear park assist

    Short story: I have always gotten a "service park assist message" since I've owned the rig (sept this year) but after replacing sensors, and more recently, taking the bumper off a second time and inspecting the wiring harness, it seems to be working as it should. Perhaps I will just live with...

    TPMS Relearn Problems

    I recently discovered my sensors were not mapped to the correct positions, so I bought one of the el cheapo Amazon relearn tools. I've spent a couple hours with it trying to get it to work. Out of many attempts, I've gotten it to to trigger a single sensor twice. I got frustrated after trying...

    Got my Tune On!

    Took it to the local tuner here in Vancouver, WA I've used for years. Old School EFI - he's big in the OBD I world, but also does a great job with the newer stuff, too. GM only. Did minor mods to both ECM and TCM. ECM: - DOD off - Axle protection via spark and via ETC off - Tip-In...

    Anyone have any experience with Paradox Mufflers?

    https://paradoxmuffler.com/ Their no-drone technology definitely has me intrigued. I'm looking to upgrade stock exhaust on my 2013 5.3, but will run far away from anything that has the least threat of causing drone. I had a single Magnaflow and resonator delete on my '09 5.3 - had great...

    Correct Tru-Cool 40k Trans cooler

    I bought the Tru-Cool Max LPD 47391 trans cooler, without thermal bypass. Hindsight, I'm thinking I should have bought the 4739 with bypass? I live in Vancouver, WA (weather same as Portland, OR) but I do use it for some cold weather / snow activities. Should I send the 47391 one back and get...
