    Remanned Alternator Whine

    2005 tahoe Replaced alternator with a reman unit from NAPA earlier this year under warranty I got out of the tahoe to check the mail and heard this whining sound and wasn’t sure if this is cause for concern or if it’s “normal” in remanned units. I figured it shouldn’t make any noise but just...

    PSA: Check Those Torsion Bar Crossmember Bushings

    I’ve been chasing a popping sound coming from the driver’s side while turning in/out of parking spaces and while accelerating from a stop with the wheel turned. Replaced a bunch of suspension parts as part of a pre-planned overhaul project and was half hoping the issue would have been resolved...

    Moog Dust Boot Question / Clarification

    Long story short, I overhauled the front suspension on my 2005 tahoe when I hit 200k miles. I had torn lower ball joint boots, etc. so I figured I would just go at it all and give the front end a new start. When I installed the lower control arms (Moog CK620380/CK620381; purchased from RA), only...

    New GM ISS = more slop?

    Recently replaced my intermediate steering shaft with a new GM (19329330) part and this thing has way more slop in it than the beat up one it replaced. I read around on the forum and saw the ISS design was updated at one point in time but wasn’t sure if this was considered the new “normal” with...

    Repeat Vapor Canister Issues

    Long story [not so] short my original vapor canister blew out on my tahoe about 2 years ago and threw carbon throughout the EVAP system. I went ahead and replaced all EVAP lines, the fuel pump (preventative), purge valve, purge canister, and vapor canister and all was good for about 6 months ...

    Soft Brakes, New Day

    2005 Z71 tahoe with hydroboost Issue soft brakes for the first 2-3” of pedal travel then I finally start getting bite. When did this start? It started earlier this year after I replaced the hydroboost unit (new GM) and master cylinder (new GM). Why? I flushed my power steering pump and ended...

    New Tires Soon, Gauging Interest in Other Brands

    I hate to post yet another "what tire should I get" question, but here I am. I am looking for input regarding tire options for my 2005 Z71 Tahoe, bone stock. I have close to 50k miles on my current set of tires (Cooper Discoverer AT3 4S, standard load) and I'm just about to my wear indicators so...

    Alternator Bearing Question **Noise Solved**

    I’ve been dealing with a whistling sound on cold starts coming from the engine bay. The sound increases as the RPMs increase but then go away at operating temp. I spray everywhere there could be an air or vacuum leak to test and no engine response was noted. Then I pulled the belt and checked...

    UPDATED* Carbon in Purge Valve = just do extra PM?

    2005 Z71 Tahoe, 186k miles all stock Long story short, I got the “tighten fuel cap” message on my cluster again and decided to just change the purge valve and vent valve. When I pulled the purge valve fitting, carbon pellets fell out and I saw the solenoid was packed full of pellets as well...

    Another Battery Light Question (sorry)

    2005 Z71 tahoe, about 186k miles. Bone stock. Twice in the past week when I start my Tahoe from a cold start, my battery light comes on and stays on during driving. The gauge in the instrument cluster appears fine, given that it bounces around a little anyways thanks to the on-demand charging...

    Thoughts on play in tie rods?

    I’ve been dealing with an intermittent popping sound from the front end. I took it to a shop awhile back and they said everything was tight but now the popping is more prominent. Thinking that the part that may be causing the issue is going to be noticeable this go-around I jacked up the front...

    Body Mount Bushings

    I’ve been dealing with a random popping sound from the front end of my 2005 Tahoe (Z71) and everything is tight with the suspension. It’ll do it when getting out of a parking space as I turn the wheel, which made me thing tie rod or ball joint. Then I came across the two front body mount...

    Bad Catalytic Converter?

    https://youtube.com/shorts/iM4LKnp44ow?feature=share I’ve noticed that after getting my exhaust manifold bolts replaced that I’m getting a little rattle from the passenger side with the engine running. I checked all the heat shields and everything is tight. When I bump the catalytic converter...

    Soaked Floorboard Fix (Hopefully)

    Well, thanks to this rain NC has gotten from Elsa I was able to finally figure out where my wet passenger floorboard issue is coming from (I hope). Lots of downpours over the past few days left my carpet soaked. Beyond pissed off that I thought it was still the EVAP condenser issue, I pulled...

    Afterblow Module Install Questions

    I ordered the AC Delco afterblow module to help with my moldy AC condenser issue, and had some electrical questions. Looking at the wiring diagram, it seems straight forward but I do not have enough electrical experience with GM products (Jeep is another thing…) so I want to make sure I’m...

    Water under passenger floor mat (yes another thread)

    I got tired of my AC smelling like mold so I installed a cabin air filter using the retrofit kit. I spent a lot of time cleaning out the HVAC box to ensure it was good to go, and that the drain line was clear. I drove around with the fan only for two days to make sure the box was dry. Installed...

    Afterblow / Electronic Evap Dryer module install

    With the summer temps brings back the dreaded “musty AC” in my 2005 tahoe. After reading, I found I can do a cabin air filter retrofit. I got the hole cut out and am just waiting for the filter and panel to arrive so I figured I’d ask about afterblow now. I also ordered the afterblow module but...

    Transmission Oil Pan with Plug

    Went out this morning to do a drain & fill on my 2005 Tahoe (Z71 if that matters) and noticed that the pan didn’t have a drain plug. Go figure. What do you all recommend for a replacement pan that has a drain plug? I’ve read that some people use the Silverado pans because they are deeper and...

    New Pitman arm?

    Long story short, I’ve been hearing a popping sound when backing out of parking spaces and after checking everything, I found a little play in the pitman arm. I took it to a shop and they said it was fine, but that I could take it to another shop for a second opinion. I’m thinking they just...

    Clear coat peeling around door handle

    see attached pictures. The door handle is the passenger rear. What is my best course of action with this? It’s a 2005 Z71, with the Bermuda blue metallic paint. I’m debating on using a straight edge to cut the loose bits of clear coat so it doesn’t peel up too much but am open to other ideas...

    Double Checking Myself on Sunroof Alignment

    Just so I feel better about it, does the alignment of the sunroof in the attached pictures look normal? I did not take a picture of the glass from the outside and now I am thinking that the back is sitting higher than it probably should be. I took out my sunroof yesterday so I could drop off...

    Antenna Cable Grommet

    Tighten Fuel Cap + No Codes + Random Starting Issues = Fuel System?

    2005 Z71 Tahoe (non-flex) Within the past month I have had the following happen, which suggests to me that they are all related: - "Tighten Fuel Cap" message on dash - no codes stored - random starting issues; sometimes the starter will crank 2-3 times as normal and it the engine will fire...

    Oil Cooler Block Off Plate Delete?

    Long story short, my OEM gasket (with rubber o ring built in) went bad and I replaced it with a FelPro gasket (flat metal, no o ring) and am still having oil leakage. Got pissed off and went with the black RTV instead but am still getting a slight seepage. Now, I couldn’t tell for sure but it...

    Service TPMS + Battery Light

    I have had three instances in the past month or so when I have gone to start my Tahoe (2005 Z71) on cold mornings and get the "Service Tire Pressure Monitoring System" notification on the instrument panel and the battery light stays on after starting. The TPMS light (or, should I say the low...
