    After 30 or 40 miles on freeway, whinning sound from front end. Gets louder but levels off. When you slow down, sounds like metal grinding, REALLY bad. If you turn at low speeds, gear skipping feeling, wheels shake. If I let the truck sit and cool for a few hours, its ok, until 30 miles of freeway, even at 60mph.
    This is the second time with this issue. Replaced differential twice; at 63,000, then 90,000 before, and here again at 98,000. Hate this truck. $50,000 piece of junk. My 98 Pontiac was 3500 bucks, and I drive it instead. I will never get 100,000 miles on this Denali, because I can't drive it!

    front differential went out after I was initially told it was a bad axle. Repair cost quadrupled
