Noises when steering in 4WD

Hello everyone, 
So I’ve recently been hearing noises and they’re getting worse whenever I turn almost the maximum, I’d say anything above 70% steer. 
I don’t know how to describe it but it sounds like something is grinding with ticking. 
When I steer in 2WD it’s ok even when my lockers are on 4x4. 

Any ideas? Thanks 

Sounds suspiciously like a cv joint. It being quieter with the hubs in 4x2 suggests the when the wheels are turning the cv joints they are not running on the worn parts of the joint balls.

i agree with Lambert also would advise fixing it soon
cos when it breaks you will struggle to turn making it almost impossible to drive home

A clicking or even a sort of cracking sound at full lock is a sure sign of a cv joint on the way out. Is it coming from both wheels or just one?

The only other thing, are you running bigger tyres, they might be catching on the wheel arch, especially if like me the front bumper was pushed back after dropping in to a rut whilst off roading, usually the sound of a cv is different?

Checking the obvious, are you on a loose or slippery surface?

The thing is that I have fixed hubs so they’re always on 4x4 and it makes noise only when I’m actually in 4WD but when the lever is on 2H and I steer it doesn’t make the noise even with the hubs locked

I believe its only the left one but I will lift both front wheels up and check

Normal tyres, just bigger engine which I believe contributes to wearing CVs right?

I heard it many times on asphalt, I’m not entirely sure about slippery surfaces, if I don’t hear it on slippery surface what does that mean?

I see, hope I can find a CV joint without having to buy the whole rod

Thanks everyone
