    Looking at buying a yukon 100k miles
    have a few questions

    1] Should I be able to get 14-18 mpg on highway?

    2] What problem areas should I look for?

    3] Most I have seen have had push buttons for
    t-case. Is this as good as lever shift?

    4] There is a small knocking noise at front of
    motor,can not hear from inside cab.Could
    this be a bad idler or ?

    5] What axle ratios did these most often have?

    6] Is there any diferance other than appearance
    between gmc yukon and chevy tahoe?
    Thanks for looking

    1.Yes
    2.Coolant leaks from manifold, front axle engaging and disengaging correctly.
    3.In my opinion NO, I prefer the TC lever
    4.Idler,Alt,AC comp, use a piece of hose to your ear to isolate the noise
    5.I would guess 3.73 or lower numerically (ie 3.42), but it might have 4.10 with a tow package
    6.No
