does this sound like a dodgy alt bearing?

[steveo29 0]

my g60 has stated to make a dodgy bearing noise that seems to come from the alt/charger area and is an random short grrrr while the idles

 

if i put a load on the alt, i.e put all the lights on at once the noise appears straight away and goes when i turn off the lights

 

the long screwdriver stethescope doesnt seem to pin point it...does those symtoms sond like a dud alt bearing?

Have you tried removing the belt & "feeling" the bearings by turning the pulley with your hand ?

no i havent...the noise is intermitant, so im not sure if it will show by hand

 

i will try though :)

steveo29, check the cambelt tensioner!!!!

Like Supercharged said ^^^^

 

However, if you're sure it's the alternator you'll definitely be able to feel/hear a dodgy bearing by removing the belt and spinning the alternator pulley by hand.

it has had a tensioner a while back...similar noise though

 

i wondered/hoped it was the alt beacuse it does it when i load the elec system
