rotational whoosing sound coming from wheel area, goes away when braking

[Lukey]

hey guys when i was driving home from work i noticed i was getting a rotational whooshing sound coming from my wheel well area, i noticed it coming from the RHF but it could be coming from LHF aswell. its there at all speeds and gets faster the faster i go, but the sound goes away when i use the brakes.

i rechecked everything i touched when i did my new torque mounts the other week, all tight.
i checked my wheel nuts on friday.
it isnt coming from my cv that has a split boot.
my brake pads still have plenty of meat, only about 30-40k on them.

i dont know the thickness of my rotors, ill bring a vernier caliper home from work tomorrow and measure the thickness, does anyone know the minimum? they are also are slightly glazed but i dont think that has anything to do with it.

ill recheck my wheel nuts again today.

ill check the hub nut tomorrow when i take my wheels off.

thats all i can think of at the moment. any suggestions?

thanks!

have you checked the brake pad shims? i had the same problem as soon as i put my foot on the brake the noise would go away...remove pads and chech the shims to see if touching?

Ill have a look when i pull the wheels off tomorrow after work.


I jacked my car up before i made my original post, and, i just drove down to the doctors and the sound seemed tohave gone away. Ill see if its there on the way home and tomorrow.

if its increasing and decreasing with road speed, my guess is it will either be a wheel bearing or diff

[Lukey]

I checked my rhf wheel bearing and it didnt have excessive play top to bottom or side to side. But if it was a wheel bearing wouldnt it still be there even if im braking?

Have u parked overnight during or after rain ? Might be surface rust on your brake discs ( surrounds where your brake pads sit on the rotor leaving a small sediment) a quick rebed of the pads might fix your issue

wheel bearing!!!! jack the car up and check for play inthe wheel affected by placing your hands at 12 oclock and 6 oclock and xchecking for movement

[Lukey]

no i havent ben, my car is garaged whenever im not at work or out n about.

ive already checked my rhf wheel bearing and its fine.

futher more to brake pad shims, i used anti squeal when i changed my pads so those suckers wont be moving anywhere but ill still check.

also regarding my 2nd post, after jacking my car up and checking a couple of things which were fine i let it down then drove to the doctors and back home without the noise being there.

staff carpark at work is gravel, maybe a small stone couldve been stuck somewhere and it fell out when i jacked the car up?

Sounds like road noise, what's the conditions of your tyres and have you potentially damaged your rim? Usually occurs on old wheels/tyres, take it to a wheel shop to get it checked out or inspect them when you take off the wheels

[stndrd]

you can get wheel bearing noises without having freeplay (I've just replaced x2 BA falcon RHF hubs & a Mazda Tribute lhf bearing kit in the last week with out freeplay)

if it comes back and your willing to make a trip to narre warren, let me know. otherwise take it to your local mechanic as you will never get an accurate answer from asking a question thru the internet about a sound from your car. it will only ever be people throwing up ideas

also side to side movement is freeplay in either your steering rack knuckle (tie rod) or your tie rod end

its not road noise. tyres are good and wheels are good.


ahok, ive only heard/felt bad wheel bearings being there constantly and with freeplay.


and im an apprentice mechanic lol, thought id try and get some opinions.


but sound wasnt there today so ill just leave it be and keep an ear open
