Rear factory locker

my pinion bearing is noisy i think ,well something is making some bad noises in
there so im going to put a diff rebuild kit through the rear diff because i have
the factory rear lokka and it works well just wandering if anyone has pulled a locker
centre out before and is there anything to look out for obviously being different to
a normal lsd centre is the actuator or anything need to be disconected
thanks ross
