    Front seal replacement question

    2012 Yukon Denali 6.2, I believe the harmonic balancer does not use a keyway? Can I use the teeth on the flywheel to hold it or is there a better method? Is the balancer bolt RH or LH thread, torque value? I figure others can use this reference as well. Thanks

    Need help debating new wheels

    I love the optional OE 22" wheels on our 2012 Denali, but.....after replacing 2 already, I have the other 2 leaking air at the bead, forgive the dirty wheels, been cold and nasty here. Maybe if I can find 2 more I will keep them, but they aren't cheap, IF I can find them. Bead sealing...

    Liftgate supports

    What liftgate supports are people using without issues? I tried a pair from Amazon, can't think of the name, but when I snapped it on the ball socket, it was a hard push, which made me nervous to install the other side. So I tried to remove it....not happening...I had to cut it off (not the...

    Which aftermarket running board motor & bracket is reliable?

    2012 Denali, I need the LH motor and bracket due to some corrosion in the mechanism. I debated changing just the motor but it looks like a pain to swap the bracket. Unless using a shop press can accomplish this...seems tricky, I am likely going for the motor/bracket combo. I have seen them from...

    3 transmission codes on startup

    2012 Denali 147K miles Yukon drives perfect, no shifting issues, I drove home from work and parked it. Came back 8 hours later I did a remote start and the engine started then immediately shut off, I figured a fresh CEL. I restarted with the key then pulled these codes. Does this sound like a...

    Performing ALC for Z55

    I want to ask this just to be sure, but with the Z55 suspension, you only perform the ALC and not the bumpstop correct? I have read you perform ALC and bumpstop after replacing components but the bumpstop is only for Z95? I see on the Tech 2 the bumpstop option is under the Z95 code, but want...

    Resistor value for rear Z55 shocks

    2012 Yukon Denali with Z55, if I wanted to place a resistor on the rear connections, is it the same 3..9 ohm as the fronts? Mainly for troubleshooting, just don't want the CEL.

    Steering rack bushings worn?

    2012 Yukon XL 1500 140K miles The front end is tight, ball joints, control arms, tie rods, no leaks on the rack. When turning the wheel I can see about 1/4" of moment, curious if this is excessive. If so, are they replaceable, do the bushings just press in and out? Quick vid.

    Question about replacing fuel lines

    This is on a 2012 XL Denali, 140K miles. While replacing my upstream O2 sensors, I noticed a small amount of rust on the fuel line under the black plastic retainer that also secures the O2 sensor. Doesn't look too bad, but I have been debating replacing my fuel pump as preventive maintenance...

    New Akebono pads squealing

    I swapped out my rear Wagner fleet pads as they were nearing the last 25% for the Akebono 1194. I did not realize the new pads came without hardware...(sigh) but my old hardware seemed good. I needed the 1194A. When I installed them, I noticed the fit was a little sloppy in the hardware. My...

    Is my front strut cartridge bad?

    Roughly 10 months ago, I replaced my front strut cartridges with the OE BWI 19420494, also used new coil spring insulators. I had a reputable shop swap the springs and all has been good. About a month ago I started hearing and feeling a light "thunk" or "bump" in the LF when backing from a...

    Did Michelin discontinue the Defender LTX in 22"?

    Need torque specs for front diff and crossmember

    2012 Yukon XL Denali. Don't want to trust the google web on this. I have a slight clunk a few months after the front diff swap, I think it's the cross member bolts, but want to go over all of them....thanks.

    Looking for MDI to replace Tech 2 for pass through device.

    I will likely keep the Tech 2, but for reprogramming and flashing modules, need to get with the times. I have no idea where to look, what to get, would like to keep the price under $500 if that's an option. Will be used with a windows laptop on vehicles older than 2016 (for now). All input...

    Single Bridgestone Dueler H/L Alenza

    Bridgestone Dueler H/L Alenza 285/45/22 This was a replacement tire the previous owner installed before I bought it. I removed all of them for a set of Defenders. Has less than 2000 miles. No repairs and it shows between 10- 11/32 to the bottom of the tread, so about 9/32 usable. Would like...

    Are the valve body seals a culprit with converter failures?

    So I'm still thinking about replacing my converter as preventative maintenance. I spoke with a couple local shops and they mentioned one area of concern are the valve body seals. For those that are in this business, does the converter fail mainly from an inferior clutch or from pressure loss...

    Occasional light lifter tick starting

    2012 XL Denali, 130K miles. Some history, long-winded but bear with me. Oil pressure sensor and screen was replaced last year due to cluster gauge going wacky. I bought this with about 82K miles, maintenance history was good, dealer oil changes every 5-7K. I changed the oil when I bought it...

    Any good shops that re-chrome wheels?

    I have a couple extra 22" CK916 wheels I would like to get refinished. Seems there aren't many, if any on the east coast, least I haven't found any. If anyone knows of a reputable shop, please chime in, looking to hopefully find one closer to the eastern half of the nation, mainly for shipping...

    Cleaning carpet without leaving residual odors

    What have others used to clean the carpets in the GMT 900 without leaving it smelling like a wet dog or carpet cleaner? Mine are tan if that matters, harder to mask any stains when not black carpet. I have an upright carpet cleaner with hand attachments, also a drill brush which works great...

    Easy mod to stop door lock tabs from rattling

    Not only the occasional rattle, but when you lock/unlock it's not a "slamming" up and down effect. I used some JVCC 1MM thick polyester felt tape. It's a large roll for this task but I have other uses for it. https://a.co/d/68bVBRB I cut 3 pieces, 2 small ones on the sides, towards the rear...

    Front differential bearing replacement

    2012 Yukon AWD After rebuilding the rear diff, I would now like to address a possible LH output shaft bearing that might be worn. I don't think I will mess with the ring and pinion, this time, but I have noticable up and down movement where the CV shaft enters the case. Does the front diff...

    8.6" axle ABS tone ring installation

    If you don't have the Kent Moote tool to install the tone ring, what is the trick to not damage the tone ring when installing? Looks like I boogered up two of them and I was being careful. I used a bearing install tool and made sure I hit the outside edge of the cage. I guess I must have missed...

    Noise in driveline, pinion bearing?

    2012 Yukon XL Denali AWD. I have had this driveline noise for a little while, seems to be slightly more noticeable and I'm not sure what it is, my guess is maybe the pinion bearing. Short history, it has 120K miles, bought it with 90K, all service is documented at dealer. When I bought it, I...

    Debating replacing torque converter as preventative maintenance

    This is for my 2012 XL Denali, for the sake of discussion, I currently I have no issues with my transmission. Going back....I was aware of the issues with the 6L80E in general before I bought this 2 years ago, so my plan was very likely to replace the converter in whatever I bought. Dealer...

    With a 2nd row bench, I can't use a floor console, so curious if anyone has had good luck with any of the hanging cup holders. If so, what has worked? Thanks.
