I have a 2001 Chevy Tahoe. I purchased the vehicle 2 years. For the year I have heard a clicking noise and a knocking noise when I turn and then the noise starting getting louder. Four months ago I was pulling out of my drive way and the noise turned into a scratching sound. I parked the vehicle for 2 days took it to dealer ship and they said nothing was wrong with it. Well little did I know that nothing turned into the rear end gear differential going completely out. Now I am with out a vehicle. This is while I have my 4 children in the vehicle with me on our way to the doctors office. I broke down on the side of the road. Could not go forward what so ever. Every time I would put it into drive it would make this horrible loud noise. I am not sure if I should contact the manufacturer or what. Can some one tell me anything if it has happened to you and how much it coast to be fixed. I have an extended warranty but it will not cover it.

Defects: ABS light on at 43,600 miles. When car is turned off a loud noise is heard beneath the drivers side of the vehicle my independent mechanic said the ABS unit is purging. At 20 miles and regularly there after, when the fog light power button is pressed, the rear window wiper briefly makes noise as if it had been activated. At 3000 miles and regularly there after, all four doors squeak at the hinges and must be lubricated weekly. At 10,600 miles the rear differential began to leak. Both driver and passenger seat squeak and do not firmly lock into position. The driver and front passenger seats do not lock into position. The parking brake has not worked since I purchased the vehicle.

Immediately after application of the anti-loch brakes at low speeds in 2 wheel high mode, the vehicle seems to "lock up" the wheels as if it were in 4 wheel drive. We get severe wheel hop and when we stop the vehicle, then restart it there is a very loud clunking sound. After that the vehicle preforms normally. The problem also goes away if the vehicle is turned off. The vehicle goes into 4 wheel auto, 4 wheel low and 2 wheel high normally at all other times. Again, the problem only happens when the antilock brakes are activated at low speeds (no problem from high speed stops) and it has happened twice in the past 5 minths.
