Glad you got it fixed

I don't believe your 6.2L would have the same part number since it's a different engine. The CV boots are the "rubber" boots that cover the constant velocity joint upfront.

No offense intended but maybe your right.

Did you read any of the posts above You can figure it out in 2 seconds if you look under the front for a Differential housing. If you want to run your vin number, you can do it here http://www.compnine.com/vid.php It will tell you every option your Denali has including AWD or not.

Also, it's the 6.2L... turn traction control off and see if you can lite up the tires? I know mine will on command, but its not AWD. I wanted the SLT so I had selectable 4x4 and could get the 3.73's.

Look under the front, If you have a front diff, then it's all-wheel drive and if you don't, then you have a 2wd

NA4 - 8600 emissions NP1 - Electric transfer case NP5 - steering leather wrapped NT9 - ?? Look for N23 - 22 gallon tank, or N03 - 36 gallon tank Also, you can run your Vin thru this website and it should tell you too. http://www.compnine.com/vid.php

Thanks, I sometimes miss it. I was very proud how it turned out. It was no street queen either. I used it off road for work. It went thru a few "re-mods" but in the end I was very happy. I wouldn't have changed a thing once I was done.

Hey Steven, what rims are these?? I like em! I was afraid someone would ask... It took some diggin.. but they are Akuza 359's 16x8. If they had the correct offset, I would of had them on my 2007/2011 truck. They fit great on the GMT-800's. They held up awesome in the weather. They were also sold under the name panther. They also had the nicest looking chrome of any wheel I've owned.

Yes it did come with 4.10 gears. In 2003, most of the Z71's on the dealers lot were 4.10's

Shocks wouldn't of caused that issue, I think its a coincident. Have you tried disconnecting the neg side of the battery to reset the ECM?

I had the exact same issue one time. Lack of use causes them to "seize" up. Some WD-40 or similar product will fix them, but I can tell you it does take a little time to work. Just don't bend the key while trying. Just spray and let sit for a few minutes, then start working the key back and forth. Might take more than once.

You sure its not spark knock? What grade fuel are you using. You could need to run 91 octane or better.

You might need a little leveling kit but thats easy enough. If you go with 9-9.5" wide wheels, you'll need 5.5" of backspacing. If you go with 8-8.5" wide wheels, then 4.5" of backspacing works just fine. Steven
