As i was driving to youghal today as i slow down i sometimes hear a dunk noise out of rear left wheel so when i got home i went to have a look i jacked up the car and the drive shaft going into the diff there is a bit of play if you move it up and down i checked the diff oil and its full i see no oil leaking either would it be the bearing on the diff or the splines on the drive shaft??? do these diffs give any trouble? anyone around cork who can have a look at it any advise or help please thanks lads oh ya its a 00 wrx bugeye
