Has anyone experienced rear axle problems with this model falcon or know of any reason that would cause it to break?

rear axle as in drive shaft ot the axles that go from the diff centre to the hubs / wheels.

if the latter then yea after i put in the LSD i smashed the cv join in the left one.
too much right foot i rekon. but when i got it replaced ay WA diff centre the guy said they are fairly common. especially the left one for some reason or another.
