16v - Alternator bearings

[Shorty434]

mk1 ph2 Valver, I think my alt bearing's on the way out. But, how easy is it to diagnose it really is that and 2. How easy is it to sort?

It makes a really loud whistle/ squeak and I've had my head in the engine, and its coming from the drivers side, it seems to speed up a little when I put some revs on which is why I thought it was associated with the alt. It's definitely a bearing noise. Just wondered if anyone had ever done one? If the parts are easily accesible...

Cheers

peice of piss, start it up, get yourself a long screwdriver and put it on the alternator (not on rotating parts obviously) and put your ear to it.
dead easy to pinpoint sounds this way, and if you really want to double confirm whip the belt off wrap a long bit of electrical wire round the pulley and pull it off as fast as you can, will spin the alternator quick enough for you to hear the noise and this can be done with all pulleys

Spot on. Cheers. I'm like 99% sure it is that....
