Knocking noise from rear

[VYruckus]

Hey,
I've got a knocking noise coming from the left hand side when i accelerate going left. It is getting louder and louder. My boot over the CV shaft is broken and l'm thinking it might be the bearing. it might be that but i want to make sure it is before i order parts.
Does anybody know anything about this?
It is a common thing?
Does anyone know what else it could be?
Cheers

do you notice it alot when in paky lots?
it sounds like the cv, if you can jack the rear and and have it out of gear and just grab the wheel and ty to "roll" it, you will notice if theres any play in the shaft
