    Bearing noise I can't seem to find

    I have a bearing noise I can't seem to find, Denali has about 144k on it now. I thought was in the rear end, so I pulled the axel's and replaced the outer bearings, no change. The noise doesn't change when turning or putting it in neutral when driving. The noise starts about 30 mph. I also...

    2008 Yukon Denali 6.2 fuel pump and module part number

    I'm getting codes P069E, P0700 & U0073. I think the P0700 & U0073 is related to the transmission hunting for gears sometimes. But the P096E is new, and I want to get my ducks in a row incase I need a fuel pump and or a module. So, can anyone give me the GM part numbers for both of these? I...

    Any point in changing the rear 02 sensors?

    I just replaced the two fronts with NTK at 135000, just wondering if I should replace the rears, or just wait till they fail. As far as I know they just tell you if your cats are doing their job.

    2008 Yukon Denali Pressure relief valve deflector

    I'm getting ready to do my oil pan gasket, then replace my oil pick up tube O-ring while I'm there. I'm thinking my car does not get the pressure relief valve deflector, because I do not have DoD. Should I go ahead and put it in there anyway? I am also replacing the oil cooler block off plate...

    Rear Main leaking, vented oil cap?

    So it looks like I have oil inside my transmission inspection cap, meaning I have a rear main leaking. I called around to see how much to replace, and one garage said that when they looked it up, there is service bulletins saying to clean the PCV system and change to a vented oil cap. She...

    Oil cooler block off plate gasket

    Looks like mine is leaking, and from what I've researched online, the original is metal. But the replacement AC delco is not (12611384), the felpro doesn't look any better (72462). Anyone have any suggestions? Would be nice to have an original metal one.

    My clock quit displaying on the navigation, then came back but would not display the correct time. I found the secret screen online. You have to go to Menu, display, then hold your finger on the lower left screen, a menu pops up, and you put in code 295660. I did all this, set the year and...

    2008 Yukon Denali P0442

    I got this code, so figured it was a loose gas cap and I checked it and cleared the code. Code came back so I replaced the gas cap with an AC Delco one. It looked ok, but I figured it was 11 years old. I also ordered an AC Delco purge valve from amazon #214-1680 ($11.63), and I'll throw that...

    This sound like a bad brake hose?

    I noticed the car kind of laboring on the way home, like it was heat soaked or something. Didn’t pull, didn’t smell anything, I pull in the driveway and it feels like the brakes are sticking a little. I get out and the passenger front wheel smells of brake lining material if I get up close to...

    Trans free spinning on 1600 mile trip.

    So, I did a 1600 mile trip in my 2008 Yukon Denali, and with the hammer down when passing at 70 to 80mph it will rev like it missed a gear or something up to 6000 rpm. Doesn't do it every time and no codes. It has 120k on it, and I've owned it from new. I've changed the fluid about three times...

    2008 Yukon Denali alarm going off for no reason?

    Has anyone had this happen? It happened twice over the weekend in single digit temperatures. One FOB was hanging on a hook, and another in my wife's purse, so no chance in hitting those on accident. When she started it later the horn honked a few times I assume to tell me the alarm was...
