    Transfer Case Swap - MP3010 to MP3023

    Yep, definitely possible on the 900s - I'm one of the lucky ones that's done it. Plug and play on that platform. Change T-case, module, and dash switch. No wiring or module programming required. Here's my thread...

    To level on not to level?

    That does look nice. I will definitely consider Bilsteins for the next strut go-around.

    To level on not to level?

    Yep, I'm definitely going to at least see what it looks like with the new wheel/tire combo first. Almost surely will leave it. New axle is doing great. No issues so far. I am thinking in the next year I will do rear wheel bearings. One thing interesting, both were G80s, but the 9.5 seems...

    I need your opinion. GMT800 vs GMT900. Which to buy?

    900 all the way from me. I've owned two, '09 LS Tahoe and '13 LT Tahoe. (but admittedly, no 400s or 800s). Also, my vote is colored by my preference for the 6L80 vs 4 speed, and the '08 makes that a moot point. Some notes on my 900 experience: - both were high mileage when I bought them...

    To level on not to level?

    Yeah, not much of a rake now. the 2" kit may be too much, and it would definitely be too much with my trailer hooked up, even with a weight distributing hitch. The rake was more pronounced before I redid the front suspension. I took measurements before and after I did that, and it brought the...

    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...

    Considering L96 6.0 Swap - Initial questions

    Thanks for sharing your swap story! So not being able to "drive comfortably" - is that just driveability issues? Bigger cam/headers/loud exhaust, higher stall TC, etc? One option I've considered off and on is boring and/or stroking my 5.3 to somewhere in the 5.7 to 6.2 range. BUT... I've...

    RIP old friend (Hwy crash and totaled 07 Tahoe)

    Thanks for sharing and so glad you are here to tell us about your accident. Your story brought up a lot of memories. My "Tahoe Saved our Lives" story happened in Aug 2023. ( Literally the name of my thread. :) ) We had no front impact, just lateral rolls, so no front air bags. But all the...

    Occasional front end pops/clunks - CV Axle?

    I'll go through everything and re-torque. I did drop the oil pan recently and had to lower the steering rack to do so. But I also remember looking up those torque values and torquing to spec. LOL, my driveway is so sloped the back end would probably be higher doing it your way! I have a...

    Occasional front end pops/clunks - CV Axle?

    Thanks for the responses. Yes definitely thinking about the CV axles. With what though? It seems like there are a lot of horror stories with aftermarket (any brand) CV axles. OEM is a possibility, but would be a big chunk of change, when I'm not 100% sure there's anything wrong with the...

    Considering L96 6.0 Swap - Initial questions

    ah yes, should have gotten that reference. My Tahoe is tuned, both engine and trans, just not from Black Bear.

    Considering L96 6.0 Swap - Initial questions

    Which Y-pipe did you use? I'm thinking of one from a denali/escalade with 6.2. But am also wondering if one from a pickup with 6.0 would work. When you refer to BBP, is that actually BRP Hot Rods? https://www.brphotrods.com/?srsltid=AfmBOoosYQgePMIA1hicggFy-DQNOxLD0RR3mWlguLtZYdUFQTxMWj9E

    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

    Yeah, I took my first Tahoe ('09 Flex Fuel) on a rockies/midwest trip in 2023. I remember seeing E85 in at least a few of the states we went through: both Dakotas, Minnesota, Wisconsin, Iowa, etc. I think I even tried it out a few times on that trip. But I've never seen it anywhere in WA or OR.

    Considering L96 6.0 Swap - Initial questions

    I’m pretty set on a truck motor, L96, iron, stock cam and heads. Iron 6.0 should weigh about the same as my LMG. As for cost, from the little I’ve researched, L96 is going to be way cheaper and easier to get than a 6.2. I’ve seen L96 with 150k for around $2k, some I think even shipped. I’d...

    Considering L96 6.0 Swap - Initial questions

    Thanks, James. All good info, will help me with planning. So you’re planning this same swap? Thanks, good fuel injector info. Yeah I’ve seen some threads where the advice was to run the 5.3’s injectors. Mines flex fuel, so sounds good. My tuner use Tuner Cats, not HP, but it still sounds...

    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...

    Random P219A (Fuel Trim Cylinder Balance Bank 1)

    Just a quick follow up on this issue: no CEL since I added the clamp to the PCV intake hose. Fingers crossed that it's resolved. Drove it on vacation to BC last week, 500 miles each way. Previously it was only long trips (100+ miles) that would trigger it.

    2007 Suburban 1500 totaled, shop another 10th generation or go older/newer?

    In 2023 my son rolled our 2009 Tahoe 3 times, going 70 mph, with me and my two daughters in it. We all walked away with nary a scratch, so I soon after bought another GMT900 - 2013 LT Tahoe. I'm a big fan of the 900s, delete AFM, do all the preventative maintenance suggested on this site, and...

    upgrade air intake tube

    Yes, 2 45s and one 90. And then two sch 40 couplers for the straight sections. No actual pipe in the entire thing.

    Crazy transmissionn temps

    I'd consider going with the OEM-style external trans cooler. My 2013 Tahoe did not come with enhanced cooling, but I've since brought it up to that standard by adding an OEM external cooler AND replacing the radiator with the OEM-style one that has built in engine oil cooler. The benefit of...

    Random P219A (Fuel Trim Cylinder Balance Bank 1)

    Well now the CEL is off. Just a few in-town drives after the weekend's road trip and it went off on it's own. Last night I noticed I didn't have a clamp on the PCV intake hose that comes off the main air intake. I installed one there - just maybe I have a slight leak there, but I doubt it...

    Random P219A (Fuel Trim Cylinder Balance Bank 1)

    Well the Dorman clamp worked as intended, no more exhaust leak, but the P219a code came back after 100 miles or so of driving on the road trip this weekend. Time to move on to looking for vacuum leaks in the PCV and evap hoses. In my thread from a year ago that I linked to above, I was...

    Random P219A (Fuel Trim Cylinder Balance Bank 1)

    Dorman clamp came overnight, so I installed it today. I thought I’d knock it out in a couple hours since I installed one on my ‘09 Tahoe a couple years ago, but nope - all afternoon. And a lot of scraped skin on elbows forearms and knuckles. But got it on, and no more audible exhaust leak...

    Random P219A (Fuel Trim Cylinder Balance Bank 1)

    Could P219A be caused by an DS exhaust manifold leak? I had this code show up a year ago on a 1500 mile road trip to CA to pick up my daughter from college. That time the light came on a few hundred miles into the trip and then went out on its own several hundred miles later. Stayed off for...
