Question about 2000 Chevrolet Silverado 1500

1 Answer

Fluid leak on or around rear hub

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.

SOURCE: humming noise coming from left front tire, just started two days!

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.

SOURCE: Recently noticed when driving over 40mph, I hear a

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.

SOURCE: rotated & balanced tires. new

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?

Will the front driveshaft cause humming if it is free wheeling


The noise your hearing is most likely a hub bearing It will look like axle shaft is moving because the bearing is what the axle sits into if the noise changes when driving and turn wheel to left and right if so if you turn left and noise changes then your right frt bearing is bad and vise a versa.

How much in ny to replace front end differential, horrible whaling hum from front end. did local shop cause this when seals were done last year, i heard they have to torque it properly or this damage will...


only if seals leaked out the gear lube.
you need to check the fluid level first,
and make sure your not hearing a front wheel bearing going bad,does it make the noise only in four wheel drive?
before you start worrying about price of front differential you need to locate for sure what is causing it.

Unbearable humming vibration in rear of car


It sounds like one of your rear wheel bearing hub has gone bad and needs to be replaced before you lose your wheel. I am thinking to pay attention to the right rear wheel hub bearing than needs to be replaced, they go for around $170.00 at Auto Zone and they can give you the step by step instructions to get the job done with common tools or you can use there loner program if you need to borrow a tool you may not have. With the car parked walk to the rear wheels and push and pull on the top of the tire (Side to side), feel and listen for any play. You should not hear or feel any play at all unless the wheel hub has gone bad. It take less then 1-1/2 hour to change the wheel hub and less if your good with tools. Good luck and keep me posted friend. Be safe.

"Humming" or "bearing" type noise in left front at highway speeds


That's a hub bearing. Replace the one that's doing it. I'm assuming this 'roar' is coming from the front, NOT the rear.
