Altenator whining

[rey]

Right, when the bearings go in an altenator what kind of noise does it make?

And when the pulley needs replacing what kind of noise do they make? Like a high pitch whirring?

Need to know, as I want the noise to go, really winding me up now!

the thing to do is get a long screw driver put it in the alt and to your ear and see how loud it is shouldnt be 2 loud works every tym do it at wrk

High pitch noise could be the fan belt needs tightening or replacing.

at present my car is whining and need a new thrust bearing.

when the bearing went in mine it wasnt overly loud but it did whine but there was a smell of burning an the battery light would flicker but that was just before it died

belts due a replacement soon, was wondering if it was worth doing the pulley at the same time to see if that cures it..

but the noise has been going since i stuck this one on, about 6/7 months ago! :wall:
