    2012 Yukon Denali AWD driveline bind in turns

    This took me by surprise, was getting fuel today and I felt the distinct 4HI bind in a turn but mine is AWD. Front and rear diffs have about 30K miles on Amsoil 75-90 Severe Duty fluid, transfer case also has 30K on the Valvoline Maxlife ATF. It felt and sounded like the rear tire was skipping...

    Would like to address slightly soft shifts with HPT

    I posted this issue on HPT but haven't had any replies yet, but it's still early. Some history so bear with me, I bought this used with about 80K and was very well cared for, Carfax had the trans service done at 50K and I did a 75% fluid change at 100K but no filter change. No issues driving it...

    Is this the normal front wheel stance/offset?

    2012 Yukon XL and I bought this used with the dealer upgraded CK916 22" wheels, which have the correct 31MM offset. This hasn't really bothered me too much but I want to get clarification before I get new tires and maybe different wheels. I wanted to try some 18's a while back and those were...

    Replacing torque converter without a lift and using floor jack/trans jack, what is needed?

    Slightly long-winded but....I have been wanting to do this for a while, at least a year. I have a spare front diff in the vehicle now and want to rebuild my OE front diff, I also have a spare transfer case I want to rebuild before swapping into the Yukon and when I do rebuild the transfer case...

    Trans fluid flow direction for 6L80E

    Before I make a mess, i forgot which cooler line at the radiator is in and out. I assume it enters through the bottom of the radiator and leaves through the top?

    Dashnoard extension panel in cocoa for 2012 Yukon

    Still available new but the prices are naturally insane. Mine finally developed a crack on one end and some of the hold down tabs are broken.

    Where is the ground wire under the radiator?

    I want to verify the integrity of this ground connection, but I cannot find it. I have the lower splash guard off, headlight out, and the fender liners pulled back, no sign of it. I'm sure it's there, if anyone has a pic or a better description of it's location please chime in. Thanks.

    Removing running board motor from bracket

    Has anyone replaced just the motor? If so, how did you remove it from the bracket? Is this done with a press or does it just R&R easily? I have a new motor but don't see how it comes out of the bracket. Thanks.

    LF door hinge spring detent issue

    I didn't want to detour the other hinge thread, not sure if this is the same for all NNBS, but with my old hinge, and my new hinge, the 1st detent is not as pronounced as the RF door hinge, meaning it doesn't hold well or stay put. I find myself needing to keep it from opening fully on slight...

    Projector headlight conversions for Yukon

    I've been looking to perform this for a couple years, have found a few options and one was the Morimoto XB Hybrid but are only available with the black interior. For me, I think they look great, but I would want the silver/chrome for the lighter colored vehicles, especially for my diamond...

    How much play in steering wheel is ok

    2012 XL Denali I'm assuming no play is allowed between wheel and rack output. Within the last year, I have replaced the front diff mounts, steering rack bushings, and in the last 6 months, power steering lines, inner and outer tie rods, upper and lower control arms, so all 4 arms and ball...

    I'm going to rebuild the Borg Warner 4485 TC in the Yukon and I'm curious if I need this tool or what other methods work to seat the seal to the correct depth.

    Wheel offset question

    TPMS sensor compatibility

    Are the OE TPMS sensors from a 2021 Silverado compatible with the 07-14 vehicles? Are they dual-frequency? I'm looking at a set of wheels/tires and they have the TPMS sensors but unsure if I can get them to sync with my 2012 Yukon.

    Can I switch from OE 22" wheels to 18" with Z55?

    I think I'm going to try switching to the OE 18" wheels and tires from my OE 22". I currently have the Z55 suspension package, will that negatively affect the ride quality if it's originally damped for the heavier wheel and tire setup, or will it not even make a difference except possibly being...

    Front lower control arms for non-police vehicles

    The parts stores state the Moog RK620888 LH) and RK620889 (RH) are the correct control arms for my 2012 XL 1500 Denali. They also state they are for the Police Pkg...are these iron lower arms the same? Just want to be sure as mine are iron also.

    Transfer case driveline lash, how much is too much?

    I've seen a few threads on this, I am also noticing more clunking when driving and transitioning sometimes from coast to load. Rear shaft is not moving, also most or all of this clunk noise in the video is from the TC itself. Debating rebuilding myself or just swapping it with a reman unit...

    Rear brake pad recommendation

    I tried the Akebono ceramic, now the Wagner fleet for their good bite, but I'm after a set of pads that grab well when towing or just repeated use (lack of fade) and don't give that slight vibrating, grabbing sound when nearing a stop. The calipers push back easy, I'm on my 2nd pair of Napa...

    Engine oil cooler line removal question

    Can these lines be replaced without lifting the motor on the 4WD models? I have the lines loose, front driveshaft out, but the metal hold down bracket seems to want to fight around the front diff. Maybe loosen the front diff and lower slightly? What are the success stories?

    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...
