    Need ATF exchange information for 2015 Tahoe

    I'm about to do an ATF exchange, pan drop, filter change, etc. on my 2015 Tahoe. I've done this before on this vehicle (4 years ago) and my 2010 Avalanche, but didn't take any notes or pictures along the way. Now I can't remember which line I pulled to do the exchange. I have the brass adapter...

    Torn cv axle boot, 3" lift, replace with OEM or extended travel axles?

    Went to do the front brakes on my 2010 Avalanche today and found the driver side cv axle boot completely torn. So I decided to wait on the brakes until I fix the axle so I don't get grease or whatever all over the new brake parts. So, my question is if I should go with OEM or extended travel cv...

    Bad alternator?

    Think I might have a bad alternator on my wife's 2015 Tahoe. Had a slight whining noise show up about a week ago. I couldn't find anything right off the bat and it didn't affect the drivability so I was gonna wait until this weekend to troubleshoot further. Today she sends me a picture of a...

    P/N for 2015 Tahoe LTZ sway bar links?

    Anyone know how I can find the exact part number I need for front sway bar links for my 2015 Tahoe LTZ? I tried RockAuto, but they list 2 different part numbers: 23237268 and 25918049. Is there some sort of VIN lookup somewhere?

    Rear driver side brakes making awful creaking sound

    Our 2015 Tahoe has a terrible creaking sound from the rear driver side. Doesn't appear to affect anything, but just sounds awful. I cannot figure out what is causing it or how to fix it. I ran across another thread here with a similar problem that turned out to be the parking brake cable. Not...

    Considering Nitto Terra Grappler G2 265/70/18 vs. Falken ATW4 275/70/18

    Need to get new tires for my 2010 Avalanche. I've got a 3" lift and currently have Pirelli Scorpion AT+ 265/65/18 (they suck, bad decision). I've run this size tire forever bc anything larger rubbed against my automatic running boards. I've since been able to shift the running boards a little...

    Do I have a stuck caliper?

    2010 Avalanche 4x4...So I've definitely got something going on with my right rear brakes. I had a good squeal going on so I was prepared to change the rear brakes. After getting everything apart, the pads had plenty of life on them but the brake hardware was broken. So I cleaned everything...

    Lifter tick?

    Got home from about a 7 hour trip in our 2015 Tahoe and my wife said the car sounded weird. Is this lifter tick? I have one of the Range devices to keep it from going into 4 cylinder mode, but this sound worries me. My 2010 Avalanche had a stuck lifter a while back and it took me a few weeks...

    Blend door actuator won't fully go into last position

    I finally got around to replacing the blend door actuator that controls where the air is going. Did the calibration procedure and cranked things up. However, it seems like it will not go fully into the last position (defrost/foot). When it's in this position, air is still coming out of the...

    2015 Tahoe new tires rubbing sway bar

    Just got a new set of tires for my 2015 Tahoe LTZ with the 22" factory wheels. I went up in size to fill out the wheel well a little better. I went from a 285/45/22 to a 305/45/22. It looks great and rides fantastic, but I just noticed a little rubbing on the sway bar last night. It doesn't...

    RESOLVED - Stripped out the cylinder head bolt hole while replacing valve cover, what now?

    Murphy's law strikes again. Was out doing the valve cover replacement on my 2010 Avalanche. Job is a breeze. Putting the new valve cover on and the two middle bolts literally stripped the threads out of the cylinder head. WTF?!?! How in the world does that happen? When I took the cover...

    HVAC mode blend door actuator not working properly

    2010 Avalanche - I can't get the mode on my heat/ac to change anymore. No matter where I set it (feet, defrost, upper vents) it doesn't really change. I got down and looked at the blend door actuator and think it's malfunctioning. When looking at it while changing the mode, I can see it turn...

    Plugs dirty after 800 miles

    2010 Avalanche - Had a rough idle problem that was solved with new plugs a while ago, but now I feel like it's coming back after only 800 miles. Pulled a few plugs (1, 2, 3, 7) today to check them out. I could be wrong, but I don't think they're supposed to look like this after 800 miles...

    2015 Tahoe - P0306 and truck shaking badly

    Merry Christmas to all! Creeping through a local neighborhood light show last night when all of a sudden the engine started running extremely rough. Truck was shaking and jerking and felt like it was gonna shut off. CEL eventually started flashing and traction control light came on. We were...

    Oil cooler line bolt or part #?

    Replacing my oil pan gasket yesterday and ran into a snag. When attaching the oil cooler lines back to the pan, I managed to shear off one of the bolts. I was able to remove the broken bolt, but now I need to find a replacement and can't figure out a part number or size to look for. It's one...

    Do I need to replace my oil pan? (picture inside)

    I'm doing the dreaded oil pan gasket replacement procedure and have my truck completely torn apart. Now that I finally have the oil pan out, I'm wondering if I should replace it. It looks like it's cracking all over the place. I can definitely feel the cracks, but don't know if that's a...

    Stumble/Hesitation AND stalling continuation thread

    Starting a new thread since the thread I started the conversation in was marked as solved. I have a rough idle on my '10 Avalanche as well. Been battling it for a long time now with no resolution. No codes, no stalls, but it sure feels like it's just a smidge from stalling when I'm sitting at a...

    Just lifted in the front?

    Is this a new fad? I was looking at Tahoes online and ran across probably a dozen of these that are just lifted in the front. Anybody know anything about this? I'm just curious.

    Need transmission replaced, anyone done this somewhere other than dealer?

    Transmission is going out on my '15 Tahoe LTZ and I'm starting to research replacement options. Talked with a mechanic buddy of mine today who agreed that it's going and needs to be replaced. He did his own on his '03 Avalanche and said he would help me if I wanted to do it myself. He...

    Anyone have a stock ride and can take some measurements?

    Curious if anyone has a stock ride and could provide some height measurements? Trying to find the right height for my wife's 2015 Tahoe and I would love to hear from someone that has the same thing but with stock/OEM parts. Would be great if a couple people could take measurements from the...

    '15 Tahoe LTZ - suspension - all four corners bad?

    My wife's '15 Tahoe LTZ has gotten very "springy" lately. We feel every bump riding down the road now. It's not stiff at all. It's bouncy. It's so bouncy it feels like we're riding in a boat. I did the "push down on the bumper" test and it literally oscillates or bounces a few times until...
