    Large gray relays under hood fuse box some 180 deg off from rest

    Sunday, 1/19/25, 03 Denali was fine for about an hour of driving. Stopped at friend's house, wouldn't start. Crank but no start. I am not sure if it fired with ether sprayed into air cleaner box. Will check if he remembers it catching. While looking for wires not connected, I noticed some of the...

    Random music playing when Tahoe started

    o3 Denali here. Radio mode started changing to Sirius on me after starting and up to 1/4 mile driving. Not sure if button on wheel is stuck or gremlin that has me using the 2 wires through dash hot start procedure is part of this. It came with a 'hold to start' button then that didn't work and...

    Service stability c0455

    Have the 3 interlinked errors, stability, traction and brake service showing up, 30 chimes to let me know about them and not a one is stored in error codes. The only stored code is misfire on right bank that moves between cylinders. Scared the not out of me at first, now going through starting...

    Tahoe LTZ chrome wheels - nasty marks - help needed

    Clean surface thoroughly and try silver polish? A lot of work with finish permeable. ReaperHWKs suggestion simplest as long as it doesn't cause slight tint to this one.

    Hold on there, y'all discussing Case 580 backhoe/4in1/extender or automobiles? Some days, particularly Monday, this born blonde get easily confuzed. Yep, I do.

    2018 GMC Yukon XL - Heavy Rain issues

    I found a new pothole on one of my ranch roads. THUMP! and carry on. The next day the dash starts throwing blinking lights, 30 chime noises and 2 solid red lights. One for AntiLock braking, another for Traction control and CEL. The only stored trouble code is for MAF but these other codes worry...

    Sold the 2019 Yukon XL SLT 4x4: 86K miles...guess how much?

    Wagons, BIG wagons but not trucks. Granted, I'm old and stuck on the labels. Peace and Out.

    Coming from Navigator...what should I buy? Denali Ultimate vs escalade??

    Yukon Denali approaches the luxo cocoon my 98 Land Rover Discovery wrapped me in. It never left me stranded but did pour water through both sunroofs in the ride along car wash.

    24' Maroon RST - lowered ??

    Mine is a white 2003 Yukon Denali that came with 24" rims/tires. Yep they helped handling but OMG the replacement cost. I'll get a pic to the forum but it will be with stock GMC 17" rims/tires. I cannot undo their welding on rear axle but it rarely bottoms out on ranch roads. And I don't have to...

    What would you do? Truck Needs Engine?

    I'm sure they are more now but we got 2 German made crate 350s that amazed me with so many parts already attached. One went in my 80 Chev truck and the other in Dads 72 GMC 4x4 that my brother and I got to drive around the USA in 72 summer. The motors cost 850usd each if memory serves.

    Traction control locking on from a stop

    Replaced passenger front bearing/rotor assy. Misplaced new sensor and plugged old back in. Could this have caused the 3, or more, amigo issues? Service Brakes, Service Stability Control and ABS error light. A few days before the 3 popped up Check Engine Light came on solid. I'd thought it...

    Suggestions for removing frame ground bolt that spins but won't unscrew

    If you can get a drill to it put a hole through and attempt to pry or crack the nut off. Alternately drill a hole close to this one and move ground to new bolt in new hole. Something I did on a John Deere loader/scraper (1975 and runs great) was add 2 new grounding points. Cleared up the, 'turn...

    Service Stability System Warning

    Nothing like a good cornice jump. If it breaks drop into tuck and go, go, GO. Was not meant in any bad way. Been skiing for 65 years now and hit 70 last month. Hoping to get some days on my 223cm Super G boards this coming season.

    Advice on purchasing a used 2003 with 100k miles

    I bought an 03 Yukon Denali with 175K on it and it has been pretty good for age/miles. Living on a ranch means dirt and gravel roads, some with ground squirrel holes. I hit one the other day doing about 20mph and the bonging started. The errors point to Stability Control and ABS errors. All of...

    making the steereing firmer

    GM power steering has always felt disconnected(?) from the road. Lol, can't think of a good analogy here; Tugboat going downstream with the barge it is towing doing the steering comes near how Chev, Buick, Pontiac, Olds and GMC power steering feels. Had a new 88 Delta 88 2 door, front wheel...

    Front Strut bottoming out after MaxTrac 2" drop

    My 03 Denali came with 22" rims/tires. Some rock rash on one rim with a torn sidewall. Other than the one they are in very good shape. 500usd if you are looking for wicked handling. They worked fine but not the best setup for ranch roads daily. Sorry if this is going to the wrong responder in...

    2005 gmc yukon xl 1500 4X4 hub nut

    Try 1" 1/4 or 1" 1/8. Use 6 sided SAE and keep pressure centered as exactly as you can while starting the nut to move. Some times a cheater pipe and tighten it a touch. Reverse direction and it should move. If not use penetrating oil and push it into threads with stiff paint brush. Let it sit...

    Expedition Max to Yukon XL?

    Dad had a 91 F350 4x4 'cowboy Cadillac' 4 door with 360 gas. We had no idea the transmission (auto with OD) and transfer case were poorly designed and figured the low mpg was size/weight related. Ford was forced to fix it at no cost. They did argue the year, 91, put it past their responsibility...
