Question about 2000 Chevrolet Silverado 1500
Hearing a humming (or airplane) sound while driving, thinking it was the right front wheel, I replaced the wheel bearing. Still hearing the airplane sound, after looking more carefully found that the inside of the left rear tire is completely black. After pulling the hub found a oily substance on the parking brake pad. Anyone know what this could be? I was thinking it could be the seal.
If not the rear wheel cylinder, it will be the axle shaft seal.
if you are still full up on brake fluid, it's axle.
Use a 1/2" ratchet on the check plug on the side of the rear diff and get a pinky finger in there to see what the level and color of the gear oil is.
If you don't get a sample on your finger, you know you are too low on fluid.
Hope this helps.

If the tires are wearing normal then its not the ball joint. If it worse while turning one way and quieter turning the other way it a wheel bearing. A ball joint does'nt make a constant noise.

yes.this means the left wheel bearing is bad, because when you turn right the pressure is pushing down on the left wheel causing noise and when you turn left the pressure then pushes down on the right side removing pressure from the left side causing noise to stop.. this is why when you turn one way or the other the noise stops and starts.

You will need to check things logically. Run the truck in the air and note where the vibration is at. Take the wheels OFF and put a few lug nuts to hold the rotors on, take the truck to 45mph or whatever the vibration is the worst. is it still there? if its gone, check wheels/ tires. if its still there, check rotors, axles. A drive shaft will make a rapid vibration at low speeds since it turns 3 to 4 times faster than the wheels. does it vibrate on or off the gas? Can you power through the vibration like go 60 and then coast back through? You have replaced a lot of parts that would not cause vibrations. Are you just changing parts willy nilly or is someone actually checking and verifying that these parts really bad?
