No locker in the front axle, so I will check the gears. As for symptoms, being my daily driver I noticed slight grinding, which i thought was the brakes and clicking while turning was obvious after engaging and disengaging the centre difflock. The wheels had been wobbly before but never like this. I could usually tighten the wheel bearing bolts and the wheel would be solid.
Thank you everybody for the help it has really made my life alot easier.
