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!
Rear end whining when on the gas, quiets out when you let off... getting repaired by a local transmission shop.
front end making a winding noise
The front wheel drive sounds like it's making all kinds of cranky noises grinds when I turn when I take off really hard it's just not a good thing
Left front differencial is making old noise
front differential went out after I was initially told it was a bad axle. Repair cost quadrupled
Actually mine is a SLT but anyway on a recent vacation i drove from MN to VA & back to MN. Over this time some of the gear oil leaked out i assume due to a failed seal. On the way home the front differential became louder and louder especially when de-accelerating. Still driving it this way (it hasnt been quite a week ) but looking into get it repaired within the next few days.
R front differential shot -
Expensive to fix....
Repair or replace
sounds of crackling or like popping rocks under truck when started up and on acceleration but then on idle you cant rerally hear it
front wheel bearings replaced because of bearing noise. Problem not fixed. Fluid change on front differential revealed alot of metal on magnet. Front taper bearing worn.
waiting on diagnoses. It definitely seems to either be differential bearings or the transfer casing
