    Transfer case cracked?!??!

    I'll be honest, this truck has been a cancer on our family since we got it.. I've dropped over 5k into this truck and Its been more headaches than it's worth. I bought a toyota because I enjoy driving my vehicle, not working on it. I hate saying it on this forum but this truck had been the...

    I understand, the cenex by me has 93 for that price... I didn't intend for posters to read it as a sams fuel, just that the cheapest 93 top tier is 2.67...,:cool:

    Won’t start when colder than 25 degrees

    Now the difference in price is 34 cents per gallon...(87 to 91) .34 x 27 gallons= 9.18 difference every tank My mpg gos from 13.5 to 14.5/8 using 87 to 91... avg 1 mpg... so 27 extra miles= roughly 2 gallons of gas= $4.66... 9.18 - 4.66= roughly 4.50 more per tank after adding in extra miles...

    Throttle body acting up

    I had a whole new pigtail that connects to the throttle body rewired, and sanded my big 3 grounds, and my reduced engine power went away all together... Would do it at low throttle, sometimes before the engine even started , it would right into it... have to wait and restart it and it would be...

    BELT TENSIONER, IDLER, ? CHATTER

    Yes, that's why they put 2 belts in my opinion, so if the a.c. went put somehow you could cut the belt and still have a serp belt to drive on... If the defroster is on, the ac kicks on at any temp, its trying to blow dry air... I had that chatter and it was a bad compressor that wouldn't the...

    Advice on Yukon XL Denali

    Service history is very important on denalis... If they did not take care of them, the diffs, t- case, even the trans, could need more than just some new fluid... If you buy it, plan on doing a $300 tune up.. fuel filter, air filter, radiator flush, engine flush, plugs, wires, diff fluid...

    Best $150 mods

    I feel it adds a little more throttle response from a stop, it's responsive and snappier when towing, and it adds a audible growl letting you know it's there.. Layman's, it's more awake... not 'tuned' awake, but it's a start...lolz
