    Cyclonefanatics are the source of all knowledge, so I'm hoping there might be car expert among you all who can help me with a car problem.

    I have a 2000 Honda Accord with a regular knocking sound in the back that speeds up as the car goes faster. As soon as press down on the brake (even very lightly) the knocking sound disappears, and then it immediately comes back the second I take my foot off the brake. Anyone have a diagnosis?

    That hooker in the trunk might have something to do with it.:shocked:

    You could just constantly ride your brakes...

    Accord is FWD. Said it was coming from the back. I'm guessing wheel bearing.

    Not a driveshaft on a front wheel drive vehicle...unless you're missing the ...:jimlad:

    Obviously something to do with the brakes most likely. Does it have drum brakes or disc?

    and can you further explain the knocking sound? Usually when the pads are about gone on a disc brake you will hear squealing or grinding when pads are gone, but knocking would tell me the car has drum brakes and one of the tension springs came off. Need more information

    i had this on an 03 honda element, turned out one of the back brake pads separated from the pad plate. pull off the wheel and u might be able to see without pulling off the caliper. Other guess is rattling exhaust or bearing

    fyi , i work on software/computers, not cars for a living

    Clear all the ice from around the wheel well if you haven't. Mine was causing something that sounded like this.
     
  13. hub bearing assembly or drum brake (assuming it is a drum)

    best to get that looked at. your wheel (rim and tire) can and will fall off if you don't take care of it. (ask me how I know)

    Accord was available with drum brakes in 2000. Now that I think about it that sounds most likely.

    The knocking sounds like someone knocking on the door. It speeds up and slows down as the car speeds up and slows down. But it continues whether or not I press on the accelerator. As soon as I press on the brake pedal, even very lightly, it stops and then it starts again as soon as I take my foot off the brake.

    The rear brakes are disc, not drum, but I'm thinking it has to be something associated with the brakes.

    My money is on a wheel bearing. I have a 2000 accord that had almost this exact same issue 3 years ago.

    COULD be the brakes, rear pads are pretty cheap and one of the easiest self maintenance items you can do (also fairly cheap to have a shop do). However, it could be a rear wheel bearing and when you apply a load to the rear hub through the brakes, the clearance between the bearing and spindle is taken up and it quits knocking.

    Dad had this on the front of his pickup. I told him to stop driving until I could look at it, he didn't listen and it finally seized. I spent an afternoon with a torch getting that thing out, then had to clean the bore up and put a new bearing in. Would have cost quite a bit at a shop to do that instead of replacing a $20 wheel bearing with an hour of labor.

    Also, as Rab said, snow and ice impacted inside your rim are hell on cars, so a car wash might be in order.

    OK, it is a disc brake..... Have you checked to see if the parking brake is partially engaged. The parking brake is a drum type brake on the inside of the rotor so it could be something with them but most likely not. Check that first.

    I would next jack up one of the rear tires and spin the tire by hand and see if you can get the noise to repeat. Make sure the lug nuts are tight on both the back tires. Try to see if there is any play in the wheel by grabbing the tire and trying to shake it to see if there is any play.

    report back....

    It could be a wheel bearing but most of the time with wheal bearings it will not be a knocking sound but a whining sound that gets louder and more intense the faster you go and braking wouldn't affect the sound unless you are really pushing on the pedal. Jacking the tire up up and checking for play will give you more info on that.

    Also when you are spinning the tire see if you can sense anything other than smooth turning of the wheel.
