    Post DoD delete ticking

    @rachealae has the engine ever overheated that you are aware of? To the point the coolant needle was at or near pegged at 260? If this has happened, could very well be a warped head, but I would expect to possibly see coolant in the oil also..but not always the case.

    AFM delete kit 13 Yukon Denali L94

    Congrats on the purchase! Well, fwiw, and I hope I don't jinx you, but I was thinking the same when I was in the hunt for mine. It seems that GM improved the AFM/DOD system after 2010.or 2010.5. To what extent, I'm not exactly sure but keeping a religious OCI of synthetic should treat you...

    '12 Denali AWD RH motor mount replacement

    I have recently replaced the LH side, was tight but the RH looks worse. If anyone can provide some tips and tricks please chime in. Does removing the RH CV shaft gain any usable clearance or working room?

    Another UOA = Used Oil Analysis, 07 Yukon Denali 6.2L w183k miles, Amsoil 0w-20 w/8.5k miles

    Or maybe compliment the Yukon with it....:cool:. Those are definitely at the right price currently. Love the C5 Z06.

    Another UOA = Used Oil Analysis, 07 Yukon Denali 6.2L w183k miles, Amsoil 0w-20 w/8.5k miles

    I would agree. I was more or less adding to Dustin's inquiry on where iron would be found in an aluminum engine.

    Another UOA = Used Oil Analysis, 07 Yukon Denali 6.2L w183k miles, Amsoil 0w-20 w/8.5k miles

    Yes, I was just reiterating that point. I was basing my iron statement of the Blackstone comment of your 0W-20 OCA, about the increase of iron. They basically said don't be too concerned and I trust that, again, over my pay grade. Again, I think the OCA looks ok, I was just giving my $.02 on...

    What is the hub and bearing of choice?

    2012 XL Denali AWD, 120K, just starting to get the faint grit feeling in the wheel and barely noticeable tire noise like the infamous worn bearing, mud tire sound but again..barely perceivable. Tires are good, Defender LTX, this sounds like a bearing starting to show it's bad face. RA has the...

    Another UOA = Used Oil Analysis, 07 Yukon Denali 6.2L w183k miles, Amsoil 0w-20 w/8.5k miles

    I don't know enough about an OCA to determine what is good or bad, but I'm curious why you chose a 20wt oil for a 180K motor over the OE spec 30 wt? Does the manual say a 20wt is ok for that year engine? I know Amsoil is good stuff, I'm just thinking on the shear over time by beginning with a...

    2011 Suburban - Front end shakes

    Meant to add this... You should be able to rotate the tie rod ends with a good amount of force, they shouldn't be super easy to rotate..but they do need to move up and down with the wheel in many different positions. A good way to check is have someone turn the steering wheel back and forth...

    2011 Suburban - Front end shakes

    How mechanically inclined are you? Reason I ask, since yours is RWD, the front hub and bearing is an easy swap. I would replace both if they are original, if one is bad, the other isn't far behind unless you smacked a curb or nasty pothole with one. A suburban is a heavy vehicle, I would want...

    Z55 front shocks bad?

    I wanted to clarify, the strut cartridge does not come with the sensor....should it? He said the top of the cartridge is hollow to accept the sensor, and is a BWI unit.

    Z55 front shocks bad?

    So here's the update, the GM 19420494 is the OE part and is a Z55 cartridge. Found one at a dealer and the parts manager put his hands on it and verified one of the #'s I have on mine, 22273763, also has the provision on the top for the sensor. I looked at GM Parts and the price is good, but...

    PLEASE HELP!! Second Row Bench seat won't flip up.

    My bench has done this but it was self-inflicted which gives me an idea on what's going on. My base is worn at the hooks so I have a new one waiting to go in, but in the meantime I have placed one wrap of electrical tape to take up the tiny amount of wear causing a rattle. If I use too much...

    Z55 front shocks bad?

    Possibly, but this another topic for later but I changed my rear shocks already for the Arnott and I have recently discovered they don't use the auto damping system of the Z55 system but only a resistor? if that's the case then I will likely swap those out. Anyway, here's what I have and my RPO...

    Z55 front shocks bad?

    Thanks for the link, that's the one I keep ending up with also. However like @91RS mentioned, there are many variables. If you take the last two digits, ie..580-4xx and change them by one number, to 32 or 31, etc, you get a different 8-digit cross reference to the OE BWI number on the strut...

    Z55 front shocks bad?

    I definitely won't blindly order the struts....good tip. I've called multiple dealers, all say the same thing, my VIN comes back to Z55 with computer controlled damping....and the only part# they have is the 19420494. I do want to keep the Z55, so the aftermarket units that use a resistor in...

    Z55 front shocks bad?

    I have no idea if this is the correct part number, but this looks exactly like the one I have, identical stickers as well. https://partshawk.com/sale/acdelco-580-433-shock-absorber.html

    Z55 front shocks bad?

    Thanks. My only guess, is this Yukon was originally sold to the State Dept, could be why it has the 2nd row bench as well, who knows. My VIN comes back to the non-Z55 shock, however the dealer shows Z55 as the option. :hmm: Is there a GM part# for this front cartridge? Is OE the only or best...

    Motion sensor constantly setting off alarm

    Sorry for the delay, I was thinking I had to pull panels down so I put it off due to extensive yardwork and some weather. Low and behold, it's in plain view.. lol. Yes, it is on top of the air duct, I have it removed now and will relocate. It seems to have a liquid inside so I agree...

    Z55 front shocks bad?

    My update on this, I cannot find anything in the Tech 2 on the health of the suspension, I will chalk that up to user error at this time. Secondly, I'm trying to locate the front strut cartridges, based on my VIN, the 2 dealers I called gave me: 19420494 and they also verified I have the...

    Motion sensor constantly setting off alarm

    It was on the vehicle when I bought it. I learned about it when I first used a floor jack on it with the doors locked..lol. Tech 2 display: Note, I did have my hood open when I took this pic. DIC message when turning key off: So I do...:) Didn't get a chance today to crawl under...

    Motion sensor constantly setting off alarm

    2012 XL Denali Unless I turn off the motion sensor when prompted upon shutting engine off, the alarm will go off not too long after I lock it up. The Tech 2 also shows that the alarm is triggered by the "Inclination" , no other triggers. Can this be adjusted or should I just replace the...
