    Driving my '09 LTZ it felt like i had driven into a sinkhole pulling into a parking spot.

    I looked at my right front and everything looked fine. Hmm. Felt weird again when I pulled out. Next stop was the same thing pulling in. Hmm. I was able to pull through the parking spot leaving and it felt less weird. Back on a highway it was fine but it occurred to me that I had used 4WD last...

    2009 Nav stereo XM ready

    Wanting more I replaced the Nav radio in my 2009 LTZ Tahoe with a whiz-bang Pioneer unit. The radio I removed works perfectly and is cosmetically perfect. I'm not sure how to go about removing the XM unit or I'd throw that in. $100 and you pay shipping from 37890 zip. Baneberry, TN.

    Traction control off --> better drive ability

    My Tahoe has been slow to respond to the throttle in turns and curves for a while. Recently I turned off traction control on a friend's bumpy gravel driveway because I was fighting that problem just going straight. Note that no lights flashed telling me it was active. It drove much better. No...

    Locking and unlocking.

    This was a year or so ago but I wonder if it's normal. I jumped out of my Tahoe and as usual hit the lock button on the door. As I was walking away I realized I didn't have my keys. I turned back to beat the timer and heard it lock. Hm. I had my sunroof wide open so I went up and over to get in...

    Window limiter?

    To fix wind noise on several of my windows and more issues on my right rear I want to change where the windows stop. My right rear clunkers loudly when I roll it down. I took the door apart expecting old fashioned mechanical stops with a missing rubber bumper. Nope. What I have learned is the...

    Electrical gremlins multiplying 2009 Tahoe LTZ

    For a while now I've been having problems with the HVAC in my Tahoe. If the Tahoe sat for more than a week the selections would "default" to 74 degrees, Rear on, Passenger on, and Auto off. Normally it's set for 72 degrees and Auto on but the other two things off. As time has gone by the length...

    Replace ltz rear vew replace with fancy camera mirror

    I'm starting to consider a nicer rear view mirror with full time camera that offers different views like wide angle or normal plus dash cam function. My issue is I don't know what all my mirror does. Self dimming, OnStar, some light sensor, what else? I guess I could talk to Crutchfield...

    HVAC and dash lights being funky 2009 Tahoe LTZ

    Many mornings after i leave my dark garage the dash stays in night mode sometimes for nearly an hour. Lately it's added switching to night mode at random times driving in bright sunshine. I've disconnected the battery in the past and had the HVAC blow heat from the dash vents. Disconnection...

    09 Tahoe why don't I see my RPO codes on RockAuto's site - suspension redo

    I've decided to bite the bullet and redo the suspension on my '09 Tahoe LTZ. I went to RockAuto and started looking at shocks. I went down and took a picture of the RPO codes for my truck; As near as I can tell my front suspension codes are 6H3 and 7H3. Nowhere in the list of available shocks...

    Who's in Atlanta? Look at a diesel 3500?

    I found an ad for a 2005 3500 diesel pickup I'd love to get but it's a "mechanic's special." Carfax says the long block was replaced, seller says it isn't running right and won't go far. I'm East of Knoxville and had hopes of riding my bike down to bring the beast home. It would be nice to have...

    Use 2009 5.3 in 2005 to replace blown 5.3?

    I can get a 2005 Silverado 1500 cheap with a blown engine. I have the 5.3 I took out of my 2009 Tahoe that's a known engine I'd like to swap in. Given that I can swap some of the parts from the 2005 onto the newer engine what will I run into? Planning to use the 2005 ECM and eliminate the AFM...

    Starter Struggles Solved

    When I swapped the 5.3 out for a 6.2 I didn't realize that the 6.2 needs a different starter. My 5.3 starter was struggling especially when things were hot. I bit the bullet and bought a starter for the 6.2 and made sure to get AC Delco. I've been dreading changing the starter with images of...

    Upgrading 2008 Tahoe LTZ

    A fellow firefighter's 2008 Tahoe is clearly having AFM failure. In looking for best solutions I've seen some 2011 Tahoes with issues going cheap. Can a 6L80e trans along with the engine and computer be used as a donor? His wife loves her LTZ and wants to keep it forever. The body and frame are...

    2009 5.3 engine

    Removed and replaced with 6.2 due in part to mistaken fault diagnosis. Engine was running strong with 220k miles just prior to removal. I mistook loss of oil to be failed AFM and bought a replacement engine to swap in to minimize downtime. Issue turned out to be completely clogged exhaust due...

    Another 6.2 for 5.3 swap going on.

    My 5.3 suddenly started blowing large clouds of blue smoke on startup. After a mere 220k miles I think it's done. I walked into the cloud to smell and I think it's got a tinge of coolant too. Whether it's getting coolant into the cylinders or not fixing the cylinder heads is enough expense...

    Left rear window hits bottom with a thump

    I'm guessing I've lost some kind of rubber bumper in the window track. Is this something folks here deal with? Is there an easy fix? The same door has a switch issue where the window switch won't go up but it works fine from the driver panel. Searching shows maybe I can just take the switch...

    Yay! I've been searching for something else to spend money on. :boxed: I've gotten the P0230 code for a while and cleared it several times. It comes back fairly quickly when I start driving.

    Is there a quality forum for Avalanche

    I've come to realize I should have bought a Chevy Avalanche for my needs. It won't happen soon but I think I'd like to swap into one. I see that bed flipping feature as a potential problem area and I'd like to hear what people are saying. This forum has been fabulous with very low noise to...

    New rear axle bearings and seals.

    Backstory... When I bought my 2009 Tahoe LTZ I went over it looking for things to fix. Found back then that the right rear axle seal was bad and that corner was messy. I cleaned it up with brake cleaner spray and left it alone. It's a fairly involved job and I wanted to see what else was going...

    2009 Tahoe LTZ 4x4 Parking Brake sudden failure

    I was trying to get my Tahoe to hold on a fairly steep hill and SQUASHED the parking brake on. As I stepped down on the pedal it popped and slammed to the floor. No more parking brake at all. I looked at the cables figuring I had popped the end off one. Nope. All good. I just forgot about it...

    Clunk when leaving a stop.

    When I accelerate from a stop I feel and hear a clunk. Also while driving down the interstate I notice it is twitchy. Every now and then it will change trajectory slightly requiring a correction to keep going straight. I was pretty confident that I had a bad bushing in the rear suspension that...

    Oil pressure sender '09 5.3 just venting

    Mine went out. Saw the CEL and noticed the gauge at 80 psi. Later it showed 0. Getting in a position where I could reach that part of the engine was tough enough. Getting the trick wire connection off had me searching the Internet for an hour. Nobody showed that connector, just descriptions. I...
