Outer Limits 4x4 Board

this is my drama.
i have a solid axle 100 series petrol full time 4wd.
last weekend while on the beach i engaged the central diff lock it started making horrible crunching sounds when the front wheels were at or almost at full lock.
no noises when driving in a straight line, my first guess was the rear lsd or front cv's.
i changed my diff oils and it made no difference.

if it was the cv's i thought they would make the noise all the time as it is a full time 4wd.

it pretty hard to tell where the noise is coming from, i can't tell if it's front or rear but it sounds horrible, the car has done minimal off road until i got it 8 months ago. i have probably done between 50-100km with the CDL engaged.

it's off to the mechanic later in the week but any ideas in the meantime would be appreciated.

Thanks
Jeremy

yes probably the CV's, in a full timer they get a groove worn in them in the straight ahead position, and they only really load up when you lock the centre diff.

it's in the shop today getting operated on, mechanic said most likely cv's aswell
