    2007 Denali whirring/whining noise with RPMs

    I got the same thing going on, not sure yet if it's the power steering pump. I checked the fluid and it was lower than in my other (non-whining Denali). Added some and will report if it gets better.

    2013 Yukon Denali XL gas tank question

    Have you identified the source of the problem? Could it be the low fuel warning is bogus and in actuality you have a lot more gas than it says you do? The gauge says the tank is full when the 21 or so gallons are added. Is that an error and it's not really full? It's either that, or it's...

    Which alternator for 2013 Yukon Denali XL? ACDelco 145 Amp?

    I can't figure out what Amps my old one had. It's not charging. At idle, it barely makes it to 13V. My other Denali at idles generates almost 15V so I know something is wrong. The vehicle has 180K miles. I get all the classic signs of a failed alternator. I am looking at this ACDelco on Amazon...

    2013 Denali XL rear springs

    How do I test that the rear suspension is OK? Does it have auto-level? When I put something even moderately heavy, I notice the rear noticeably sags. 2013 Denali XL, 180K on the body. Upgrade rear shocks and springs with something stiffer? What are the springs and shocks that come with it?

    Got a second GMC Yukon Denali, 2007

    Ah, got it. You are right. There is that M mode which can select the gear. It's for my son, his first car. Wish I had a car this nice when I started driving. My first ride had a 3-speed tranny and an AM radio. I wanted parts and knowledge base compatibility between two vehicles and that does...

    2013 Yukon Denali XL gas tank question

    So I know the gas tank is 31 gallons. Yet when it's flashing you are low on fuel, I can only add something like 21 gallons, like yesterday, or 26 gallons if it's completely empty, on zero. Either the sending unit is not right, or .. what? If I added 21 gallons, why it was saying you are low...

    Got a second GMC Yukon Denali, 2007

    2013 and a 2007, Both have 180K miles Got the 2013 a few months ago, am pretty happy with it. The ideal SUV. Lots of room, sold the 3rd row seats. One owner, garaged, well maintained. Well the front ends needs lower ball joints but while at it, will replace other front end components. Just...

    180K miles - do O2 sensors?

    Have 2 GMC Yukon Denalis.. both have same mileage, 180K. One is a 2007, the other 2013 XL. The 2007 one recently spat out a O2 sensor code, on one sensor. Got it replaced, code cleared. But this raises the question, should I replace the other O2 sensor which never threw a code. And on the...

    AC Delco or Moog front end rebuild kit for 2013 Yukon

    Also, how do I test rear shocks / compressor system? I have never raised the rear, or is supposed to be auto-level? When I load something heavy in it, the rear noticeably sags. Maybe upgrade the springs to something with a heavier rating? and shocks?

    AC Delco or Moog front end rebuild kit for 2013 Yukon

    2013 Yukon Denali XL, with 180K miles on it. This is the kit I got. Am I missing anything? Does the Moog stuff in the yellow box represent their HD line or is it the cheapest stuff? Thinking about adding wheel hub and bearing assemblies to the list. Does the Moog HD line have good wheel...

    AC Delco or Moog front end rebuild kit for 2013 Yukon

    I have 175K on the 2013 Denali, is it worth doing the hubs and axles? Is your 2007 Denali AWD? I think all Denalis are, just making sure.

    AC Delco or Moog front end rebuild kit for 2013 Yukon

    2013 Yukon XL Denali, 6.2L AWD Nothing impressive on RockAuto, the best kit they have is MevoTech 8-piece and based on the reports, it's mediocre. Is there a similar kit based on Moog parts or OEM AC Delco? The rearch revealed nothing on Ebay, Amazon, this forum, etc. I do not want to buy all...

    Which tuner to disable AFM?

    These are one-purpose devices. The DiabloSport has the capability to modify performance. Make it run on mid-octane only for a considerable performance boost. Did that on a 5.3L and was impressed. Got mine i2 for $200 used on fleabay. Now it seems to be broken. I would need another license anyway

    Which tuner to disable AFM?

    The 2013 has the 6-speed.. are you saying you can't bump it up to the 6th ? I can deal with 5th, will get a tuner shortly anyway.
