    Default Grinding/winding sound when down-shifting

    Ok here's my story. I have a 99 tahoe. everything was fine until i went on a small trip to north carolina from south carolina. (about 100 miles) anyway it ended up snowing very heavily so i drove in 4WD for about 65 miles. I spent a day in NC then my U-joint broke going down the hwy, So i limped it to a shop and had it repaired. After that i headed home and noticed whenever the engine downshifted or i downshifted it manually there was a grinding/winding sound (Not constant, the sound would come and go)

    I changed the fluid in my transfer case and both differencials and i still have the same issue. Please any help would be greatly appreiciated.

    i just wanted to be more clear about the sound it's making. It's more like a scraping sound. It sounds like the the brake pads are worn down to the caliper, but they're fine.
