GTV alternator - bearings or new unit?
As the title suggests I have seem to have a squeaky alternator. It's my own diagnosis using a length of tube to locate the noise.
A couple of months ago I had the cam belt, tensioners, etc replaced along with the water pump (hence i don't believe it's these). The garage used all of the locking tools, so a good job!! He told me that the aux belt, tensioner and pulley also could do with replacing. Being a semi-keen home mechanic i have changed all of these bits myself.
However....... there is something on the aux belt system that is still causing a sqeak and i seem to have narrowed it down to the alternator (rear lower pulley). If i back the tension off the belt slightly using a spanner on the tensioner it goes away. Likewise if i drive for a bit it goes away.
My question is can i replace just the pulley to stop the squeak, as the alternator charges and seems to be working ok electrically or is it a duff tensioner?? I have heard the alternator replace is a 'mare.
