Hello there. (galaxy tdi 1.9 v-reg) I'm after the name of the shaft that runs behind the alternator (it may be part of the alternator bracket? but i'm not sure, its hard to tell). If you were looking down on it, the shaft has a tension-er on the right hand side (which is on the right hand side of the alternator), and the left hand side has a pulley bolted to the shaft (which is on the left hand side of the alternator-but underneath). This shaft has worn, making the belt squeak all time. My garage has informed me that this was a common problem with these vehicles, would anyone here know if thats the case? (i hope i'v sort of made it clear on what i'm after). Regards-Ben.
