I spent some time today getting to know my new XL Denali, specifically taking out the jack equipment, lowering the spare, making sure I could get it all the way out, finding the locations for jacking up the front and back, etc. It certainly isn't easy or clean work, but not terribly difficult either (although I didn't actually remove a wheel and replace it with the spare). One thing I noticed is that the crank bar assembly used to lower the spare tire doesn't quite clear the bumper while making the revolutions. If you're real careful, you can tug on it just as it's coming around to the bumper for each crank, however, it's best to use a towel or something soft on the end of the iron, so it won't damage the paint on the bumper. If they had just extended the length another inch, that would have taken care of the issue. I'm wondering if anyone has put together a custom spare rig that would allow a true full size (i.e. 17" or 20" setup) to be stored underneath the vehicle. I asked my dealer service advisor once, and he asked a tech, who said they had done it before. But now that I've spent some time underneath, I don't see how they could, unless they removed the spare winch and did some kind of welding of another cross-bar in order to properly center the location for the larger spare. Has anyone heard of anything like that? I ask because I've had true full size spares in the past, and they come in real handly. They can make a real difference, especially if you get a flat while on vacation, and you're in an area where there isn't an abundance of locations to get the tire repaired (e.g. up in the mountains enjoying the snow). It can really rob an entire day sometimes, and it's not good to drive on a wheel/tire that's a different size like that, particularly in winter weather conditions. Please let me know if any of you have heard of a way of mounting a true full size spare (in my case, 17"). Thanks. Mike |

Replying to: mikesocal (Jan 25, 2006 6:14 pm) I do know the owner's manual says that after you change the flat tire, you can store it where the spare came from. I also have 17" wheels. My guess is that the spare is close enough in size that you can drive on it safely for a long distance at any speed. Equipping a vehicle this big with a small spare would be too dangerous. It is probably the same circumfrence as the regular tires. |

Replying to: ahightower (Jan 25, 2006 7:00 pm) The supplied spare is 16". Specifically, it's a P245/75R16, Goodyear Wrangler ST, with rating of 109S. The OE tires on the Yukon XL Denali are P265/70R17 Wrangler HP, with rating of 113S. I think it's fine to drive on a spare that's slightly smaller and with a different rating for up to a day, as long as the roads are nice and dry, and the vehicle isn't heavily loaded or pulling anything, particularly if the spare goes on the rear. However, if the spare goes on the front, or we're up in the snow where the road conditions aren't so nice, then I think it could affect handling negatively quite a bit. By the way, I crawled way under to check the clearance of the tire all the way around with a measuring tape, and it looks like there's another 1.9", which should handle a full size wheel/tire combo after all. It didn't look like it had that much clearance when I glanced at it earlier, but the tape confirms it. I suppose the only issue is when mounting the flat wheel/tire, it would be good to have some sort of wheel cover that could be put in place, to prevent road debris/hazards from damaging the aluminum wheel (particularly if I upgrade to some really nice rims). They just need to make the jack handle extensions a little longer, so the jack handle won't slam into the bumper when cranking! Regards, Mike

I've got an 03 Denali with 58000 miles. at the 50k checkup flushed the tranny. Now, we have slipping in 3rd and 4th. Dealer says its a seal and could be whole transmission. Seems like this is a recurring issue with all Denali's. Also have bad bearing in front differential. Cost on tranny = $1200 to $2600. Cost on differential = $700 to $1000. I can't believe this happens on a $50k+ vehicle with only 58k miles on it. It really sucks. |
