wheel bearing or Brakes?

[sudz]

Hi guys,

Just switched over to my summer tires this morning, and confirmed a sound I was hearing was not in fact my shitty, hardened, poorly wearing winter tires.

When I turn Left There is a very audible "rubbing" sound that I can feel through the car as well. It goes away during straight driving or right turns. It comes from the passenger side (fairly sure front passenger side tire)

it has been getting gradually worse.

At first I figured it was brake rub, but now i'm not so sure.

I have a few theories, just wondering if anyone can tell me if I'm in the right direction:

Worn Wheel Bearing,
OR
Dragging brakes
OR
Rotors worn in so that little "lip" is rubbing when things flex a bit when I go around corners.

What gets me is it can be the slightest bend in the road that causes the sound to appear, however it sounds/feels stronger the more lateral G force is applied. a sharp turn at creeping speeds in parking lots is virtually inaudible.

I swapped the tires over this morning, nothing obvious hanging down unfastened that would be rubbing.

Thoughts?

Car has 236,000km on it.

Also, Probably not of consequence - I was hearing this a BIT over the past month, but the car sat outside unused for 2 weeks until a few days ago (was on my honeymoon!) - I feel like it got worse after that, but at the time I figured it was just rust on the rotors. First time its ever NOT been driven for more than 2 days.

if it sounds like sheet metal rubbing could be the front brake shield. If it's more of a grind i'd probably say wheel bearing. I had my front right bearing go at about 90k. When turning left going downhill was the only time i could hear it.

could a CV joint make this symptom?

[nepal1344]

possible...it's been years since i've had to deal with one of those so i don't remember the sound that makes. If i remember right thats more of a clicking sound as the 3 bearing go around in the socket.

Sounds like a wheel bearing to me.

Not a CV joint symptom. CV joints will click as you turn the wheels either way, (very light click)...(but not counting it out)

If it was a bearing you would hear it even during straight line driving, a humming or whining sound, (but not counting it out.)

Since you notice it mostly during a turn I'd check out the lower ball joint and/or brakes, and /or strut mounting.

Anyway have it diagnosed asap....if it's a ball joint it could lead to dropping a wheel at the worst time.

Just my thoughts. : )

The front bearings on the 3s are quite beefy. They have an inner bearing and an outer. If just the outer goes like mine did you only hear the problem when the turning Gs pull the weight to the outside wheel. The inner bearing is enough to handle the car in a strait line so no noise until turning.

Never say; only or always when it comes to automotive problems ; )

You may be right in most cases, but I had my front outter bearing go early in my warranty period...and it whined like a bitch. They Chocked it up to a defective bearing from build.

I did not say in ALL cases I said if it fails the same way mine did. Please read my whole sentence before trying to correct me.

now now...

Its getting gradually louder. However I got it appraised - Trading it in for a new honda accord. They documented the noise during the test drive - So I'm assuming i'm fine to trade it in with that and the value given was including that "issue" whatever it may be.

Old thread.. but i had the same problem with my car. Dealer diagnosed it as the wheel bearing. Replaced under warranty (luckily) and problem gone now.

Hey everyone.. I'm wondering if anyone can help me out on here... I am going crazy trying to figure out my car keeps shaking while braking.

I know the first thing people will say is that it's the Rotors. However, I have changed my rotors 3 times in the last 15000kms and I have used all Premium Rotors. Raybestos rotors to be exact. The car is fine for about 5000kms and then it starts to shake violently when I brake again. It all comes mainly from the Front Passenger side.

I have also changed my springs to Tein H Tech, it has a new Brake Caliper, a new Wheel hub, and a new Wheel Bearing..... and the shaking still continues... I'm going crazy.

I am going to change my front brake rotors and brake pads for the 4th time this weekend hoping it will go away forever.... but for some reason, after 5000kms it always comes back.

Has anyone experienced this before on the 3 at all or is my car just cursed and I need to get rid of it?

thanks for your help.

Maybe that new caliper is dragging slightly and it takes about 5k or so before your new rotor is cooked and shaking?

After you've 'fixed' it again constantly check your wheels after driving and see if that front passenger side is any hotter than the rest.

If it's shaking and then when you replace the rotor the shaking is gone, somehow you're cooking that rotor.

I would be looking to that caliper, and maybe re bleeding the brake system if there was any chance that it wasn't done properly when it was replaced. You should be able to tell pretty quickly if it's dragging.

Make sure that youve installed the new caliper correctly too. Make sure the guide pins are fully screwed in to the knuckle, and make sure they move freely.

If one is binding up and the other isn't, it would alwso cause you to shake n brake.

[bukjoe]

thanks for all the tips everyone!

I have replaced both pads and rotors once again.... I also re-bled the brakes and changed the Brake Lines just to be sure again. I have been checking to see if one side is hotter than the other, but in this weather everything is hot.

Anyways, for now everything is running smooth and new again. Although its only been 2000kms I will post again once I hit 5000kms and hopefully come back with good news.

Good luck!
