I spend 5 hours replacing the driver's axle! Worse job I've had to do so far. Turns out the noise I was hearing was not the axle, the bearings are bad too!!!! The CV boot had leaked most of the grease anyway and was rusting inside. I don't think the bearing will be a DIY though. Sick of buying special tools every time I work on something.
