Title: Whining Noise
Post by: scott.eden on 03 February 2012, 17:06:11

Hi guys,

I have a very slight whining noise when going in a straight line, But a soon as i get up over 45mph it goes off or not so bad.
Could this be a wheel bearing ,or would a wheel bearing noise be there all the time,  Seems like coming from back but not 100% sure.
Any help guys.

Is the whining noise there for a specific time even though its only until 45mph or its constant throughout the journey?

Hows your brake pads? seized caliper maybe? and are you getting some sort of vibration?

I would expect a failed bearing to be continuously noisy when in use, although if it is only just starting to go then it is possible that once you reach 45mph you are creating enough road noise to mask it.
The only surefire way to check the wheel bearings is to jack it up.

Generally speaking, if its a wheel bearing, you should be able to ascertain which side is faulty when driving by loading one side at a time i.e. going round a bend.

If you steer right it puts load (weight of the car) onto the left side.  If the noise increases whilst steering right then the fault is on the left side.  Conversely, if the noise goes away when steering right then the fault is on the right.

I've also seen instances when driving straight ahead even slight - and I do mean slight - movements of the steering wheel can induce said whine and give easy diagnosis.

You then need to find out if its the front or the back.

Jack up one corner and secure on stands.  Hold road wheel at 6/12 oclock position and rock assembly gently in and out.  By that I mean push with one hand and pull with the other.  You are feeling for any possible play in the bearing and movements are minimal.

Try the same whilst holding at the 3/9 oclock position and repeat.

If free movement is felt then get someone to sit in the car and apply the footbrake and keep it applied whilst you repeat the test above.

If the movement disappears when brake applied then its a faulty wheel bearing.  If its still there its a fault in the suspension bushings.

Hope that helps a bit.   :y

Just reread you original post.  If the noise is constant dose it get louder/higher pitched as you speed up?  I'd be inclined to diff or propshaft bearing though the latter tends to give vibration through the seat into your harris when driving.

hi,
Thanks for the help guys,

There is no vibration at all when driving. but the noise is very minable buts its there, and only at very slow speeds.

Will check Wheel bearings today and see if any play .

Thought i might mention that i have had for new michelin tryes fitted.
