Whiney whistle noise from car at lower speeds?

Take it to a car park, drive full left lock in circles, then right - and listen, it'll given you an idea of whether a wheel bearing is going.

I'm not sure but I think I may have a rear wheel bearing going..... What will spinning round in a car park do? Just make the noise louder and more obvious?

sparkychris the lock to lock in opposite directions will highlight the clicking of a cv joint on its way out on a fwd car, not a wheel bearing. On the front if you hear a louder groan when you put it into a right hand bend, it will point to the left hand front wheel bearing, and vice versa. You are throwing the weight of the car on to the weak bearing and exaggerating the fault.
On the rear, you might be able to narrow it down by having an astute passenger sitting in the back and listening intently to where the noise is coming from, but in reality, jacking up each corner and spinning and rocking the wheel, listening and feeling for play is the best route.
The OP might like to narrow down the whining to his insistent, ineffectual trolling of this board.

Lock to lock turning will pit more weight and stress on one side and can most certainly be used to listen out for wheel bearings!.


Is it disc or drum rear brakes? If the latter I've seen certainly clips break and rub slightly against the drum causing such a noise

The rears have discs. Could the discs be warped? There is no shaking at the steering wheel whilst braking.

Could it be a cracked spring?

Ask a garage to look at it.

That is the usual way of finding out which one, but it can work against you.
If the inner bearing is going then it works opposite ie, going round a left hand corner increases the noise you'd think it was the RH bearing, but it could equally be the inner bearing on the LH hub loading up as weight is transferred onto it.

I'm not nit picking with you Colino and i would do exactly as you suggest, but once a while it will be an inner bearing on the opposite side failing, some of which inners are notoriously difficult to diagnose without some weight on the bearing, which is impossible to add when you jack the thing up to spin it freely for confirmation.

Your right G&S, if a bearing goes beyond the early stages, wouldn't be the first time a pro has been caught out and changed the wrong one!

i had to go on the bus to my local factor to get a new bearing and on my return i inadvertantly left it on the bus
have i lost my bearings?
also i had a new battery delivered today but i warned the van driver not to start anything
