i have this weird noise that only occurs when doing 50mph or more. it sounds as if i got a SC whine, at the same time it also sounds like my belts are dry. i checked the belts and they seem to be looking good still. i just wanted to see what you guys think it is before i take it to the dealer for diagnosing.

 

Any shaking? Sounds like maybe a wheel bearing is bad.

 

VERY light shaking

 

How positive are u that its a wheel bearing?

 

I had my wheel bearing replaced because at high speeds (50mph +) I could literally hear my wheel spinning. High pitch sound.

 

turn the wheel if the pitch of the sound changes it's a bearing if it doesn't keep guessing.

 

if you can turn the rear wheel at speed you have a MAJOR PROBLEM!!!

Try jacking car up-use jackstands- have friend spin REAR wheel as you use mechanics stethascope and listen to bearings from backside

 

guess you never change lanes on the interstate then? never go around a corner at speed where you have to turn the F'n wheel to stay on the road.


jacking up the wheel is a waiste of time you completely unload the bearing and it's not going to do dick squat.

 

turn it while parked or driving? and if at driving, at what speeds?

what do you mean turn the rear wheel at speed?

 

I was being sarcastic and forgot to go red ink -
the visual I got of turning the wheel (tire) at speed- the rear wheel turning out quite far- like it was a front wheel,,,and it being the rear wheel bearing you are looking to test,,,If the wheel goes in and out several inches- you may have a bearing problem

cking the rear wheel bearing can be done by lifting the car, cking for lateral movement and listening with a mechanics stethascope while the wheel is spun by a helper
If there is anything bad going on it should be audible

Yes you could swerve on the road to load and unload bearings, but IMO starting with a safe inspection rather than discover the customer has waited a lonnnnnngggg time to report this funny noise..bearing fried burnt etc etc...
Not something I want to put under stress test when non-destructive testing exist

Must be part of gettting older-caution is exercised over bravado

 

thanks, i will make sure to do the movement test tmrw. i dont have a stethascope but i will try to move it in and out. is there any chance its the front wheels?

 

noises travel well in the car- have to drive it and listen to it besides cking the parts all around
rear wheel bearing is a common failure

If its front brearings/cv then with wheel at full turn, move slowly forward listening for click click click

mechanics stethascope 5-10 dollars at harbor freight or any parts store

 

i think im gonna have to hold this off til next week or maybe tmrw. it feels like 9 degrees out today

 

an alignment shop can raise the car and ck the bearings for you, or a small private import shop put it on the lift,,you can even use floorjack and jackstands

PLEASE anyone using floor jack `always use jackstand(s)`

You would be surprised how painful that crushing 3400 pound weight of a car really is when the jack hydraulics leak down pressure..or car falls of the jack---I've seen it all
The bad part is you cant always lift the weight off without killing the patient
