Hi , new on here but not to the Vauxhall scene ( my other car is Silver mk1 Astra GTE 4x4) i recently purchased a 3.0 cdti Signum Elite which has developed an annoying resonating rattle which I thought was an exhaust heat shield or similar, it has got worse and turns out to be the alternator bearings , on looking at it , it looks to be an awful job to get it off , could anyone tell me exactly what's involved ? Are there any shortcuts etc ? Also I believe it's possible to replace the bearings in the alternator once its removed, can you get a kit for this or can I go to my local bearing shop with the numbers ?

Cheers in aadvance ant
