I'd also like to add that patience is key.

I have a 2009 Suburban. I left it in to tackle it another day. Whoever designed this vehicle should be taught a lesson as it were. That said, I'll try taking the fender liner out and the wheel off. The thing is, the AC lines and the firewall make it a real tight fit. It's a very stupid design.

Yep...fender liner out, a couple swivels and extensions, patience and focus is key. It's a huge PITA to do. I did mine last spring. Too me a half hour to do 1-7 and about 2 hours for #8....

I'd imagine you've got it out by now, i have a 07 Yukon XL with the 6.2L and i was able to get mine from underneath, burnt myself a few times on exhaust as it was still hot

Tahoe Spark Plug #8 Tip
Like others I struggled to figure it out - but here's what worked quite well.
Problem: My 3" socket extension was too long and I just couldn't reach that bugger from the underside, and I was determined not to take off the fender liner.
So here's what worked -->
I started with a 3/8" drive spark plug socket, then "attached" a 3/4" shallow socket to the hex top of the spark plug socket. I used some electrical tape to fix them together. This gives you a very short "extension" that actually fits between the A/C components and the exhaust manifold. It takes some reaching, but you can get the socket onto the plug first, then attach the rachet onto it and actually have room for about 1/4 turns.
I did the other 7 in about an hour, #8 using this method only took about 15 minutes. No crawling underneath, no wheel removal, no skinned knuckles.

I just bought a 07 Yukon with 99000 miles on it so Ill be changing the plugs soon. I was wondering if this tool - http://www.amazon.com/GearWrench-81...UTF8&colid=6PGR3QB234A2&coliid=I2HGMKUK65T4GD would make it easier to get the #8 plug out?

So it was worth the $60?I need to change mine.
Hello Everyone, New here.
Just wanted to add to Monolith092068's post..
First of all I didn't feel like yanking the wheel and inner well so my stubborn self had to try my own way... (FAIL,OUCH,My arms hurt now from the cuts)
So I Saw Monoliths Post and taped a 3/4 short to my 5/8 SPARK plug socket.. (Perfect length) ..
Now here's my two cents..
If you have meat hooks with five sausages for hands then this may still be too tight... So just pop the bolt for the dipstick and slide it out, and that will increase the room enough to get your meat hooks in there...
Great idea, thank you. Just wanted to add to it... Now next time maybe I'll come here first.. Haha
Sorry I see post is old but maybe someone will benefit..
Edit.. Thanks to my wonderful organizational skills couldn't find my swivels... So I was limited in positioning also..

Take that heat shield off and that little bit of room helps a lot. 3- 10 mm nuts and it's off.

I went in the right wheel well. Took down the fender liner and it took me less than 5 minutes to change it.

Do the first seven and plug wires at home then go to best friends house for BBQ and birthday party and ask him to do #8 since he is better at it and doesn't have "girly" hands like you do.
Note: I am a software developer and systems engineer which is why I have "girly" hands. It still took my friend about 45 minutes to do them and the only reason I did not try it myself was because I saw how much of a pain it would be and we were already late for the birthday party.
